in magnetic card reader allows fans to order directly from their seat. The order is radioed to  
the kitchen, filled and delivered right to the seat. Payment by credit card is made,  
authorization obtained over the radio network and on to the next fan! The system is so quick,  
additional kitchen space was added!  
§ Swedish Railway who introduced “the first computerized conductors in the world”  
equipped with a hand held computer and an Extech Mini Serial Printer enabling passengers to  
purchase their ticket on the train. A magnetic card reader, integrated right into the printer  
means the passenger can pay by credit card as well as cash. The magnetic card reader is set to  
read tracks 2 and 3 simultaneously, decode the data and transfer it to the hand held computer.  
Extech Data Systems — Ten Years On  
EXTECH Data Systems nowadays designs and manufactures battery operated, portable printers  
for portable and mobile computing applications. Powerful micro-controllers on highly integrated  
circuit boards manage all the features supported by the printers. Custom firmware and printer  
designs are provided to meet a wide range of application requirements including special graphics,  
simultaneous read of dual track magnetic cards, datalogging, etc. The user may choose impact or  
thermal print heads. A full range of communication interfaces is available: serial (RS232),  
parallel (unidirectional and bi-directional), infrared IrDA or ASK), and magnetic card reader. All  
data interfaces are DOS and Windows compatible. Integration with hand-held computers, PDAs,  
pen computers and notebook computers is easily accomplished by OEMs and their system  
integrators.  
The printers may be operated from a battery pack or from an AC power adapter. Battery  
operation provides up to 2 hours of continuous print time - more than sufficient for a normal  
shift’s work. A fast charge circuit fully charges the battery in 90 minutes. The high impact plastic  
housing encloses easily loaded, single or two-ply paper rolls. Connectors are placed for wearing  
comfort and to minimize exposure to the elements. Membrane switches with bright LEDs are  
easily reached when worn on a belt or placed on a desk. Typical applications include field sales,  
field service, meter reading, route accounting, ticket issuance, and more. Recent product  
developments include:  
§ Series 2000 (updated impact printer range) and Series 2000T (new thermal printer range).  
The new products incorporate a larger paper roll, a new IrDA wireless communication  
system, an improved battery charging system, large memory and a new body housing with  
built-in belt clip  
§ Built-in magnetic card reader version especially suitable for field applications where  
payment is preferred at the time of service delivery. Mobile point of sale applications  
(EPOS) can also benefit from use of this new printer. Integration with wireless systems  
makes credit card authorization possible (EFTPOS)

Section 1 … Preparing the Printer  
Introduction  
This guide summarizes the programming, operating and maintenance features of the SERIES  
2000T, Series 2000i and Series 3000T Extech printers. This section should be included in your  
operating guide for the final users of the printer.  
Initial preparation of the Printer  
§ You must charge the battery cartridge before you can operate the printer.  
·
·
·
To do this you must install the battery in the printer, or  
Use a separate battery charger (Part Numbers 767600 or 767700).  
You will need an Extech (9VDC/1.0A) power adapter normally provided with the printer.  
§ Insert the battery into the printer.  
·
To remove the battery door at the back of the printer, place a coin into the slot and  
push --- this releases the lock; (see figure 2)  
·
·
Remove the battery door by lifting away from the guide rails.  
Install the battery cartridge in the battery compartment located at the back of the  
printer (as shown in Figure 2).  
§ If the battery has not been previously charged in an external battery charger, you will need  
to charge it overnight in the printer.  
·
Place the power adapter into an appropriate wall socket; then plug the power adapter  
cord into the connector at the rear of the printer (see Figure 3). The yellow <Charge>  
light will illuminate.  
·
Leave the battery on charge for 12 hours.  
§ Select a serial communication interface RS232 or IrDA. (see figure 1)  
·
·
·
·
Dip switch #8 in the “on” position selects IrDA interface. In the “off” position, RS232 is  
selected.  
If RS232 interface is selected, connect the data connector and set the serial  
communication parameters: Baud rate, Data Bit and Parity.  
If using RS232 you also need a cable such as Extech’s part # 5892RJD9; this plugs into  
the serial connector at the rear of the printer (Figure 3).  
If interfacing to a PC, Set MS-DOS and Windows variables.

Section 3 ... Battery  
Battery Recharging Operation  
§ The Extech Printers features an internal fast battery recharge system. This system is  
designed to fast charge the battery cartridges in 90 minutes using 120V/9VDC/1.0A  
power adapter (PN# 152120). This adapter is designed for North American use. Both  
220V (PN# 152320) and 240V (PN# 152340) versions are available for international use.  
§ The battery voltage, temperature and maximum charge time are monitored during battery  
recharge cycle.  
Initiating Fast-Charge  
§ The battery Fast-charge is initiated, when the power adapter is applied to the printer.  
§ The battery's voltage and temperature are checked by the fast-charge controller before the  
start of the fast recharge process.  
§ If the battery voltage or the temperature is outside of the fast-charge limits, the charger  
defaults to trickle charge at C/64 rate.  
§ If the battery voltage and the temperature are valid the yellow <CHARGE> LED is  
illuminated and the fast-charge at the 1C rate is initiated. The battery temperature and  
voltage limits are as follows:  
Ÿ
Ÿ
Temperature: less then 50C  
Voltage: greater than 2 VDC or less than 7 VDC.  
Fast-Charge Termination  
§ The controller continues the fast-charge process until any one of the following charge  
termination conditions are encountered:  
Ÿ
Ÿ
Ÿ
Peak battery pack voltage is detected.  
Recharger Timer time-out (90 minutes).  
Battery temperature greater then 50C  
§ The yellow fast <CHARGE> LED is turned off at the end of the fast charge cycle and a 5  
minute Top-off charge cycle is initiated. The Top-off charge cycle insures full battery  
charge.  
§ Pulsed trickle charge cycle follows the Top-off cycle. The battery is trickle charged at  
C/64 rate.

Resident Character Sets (S2000i)  
§
There are 3 resident fonts for the 2000i.  
CHARACTER NAME  
MSP FONT  
International character set (Standard)  
Hebrew character set  
IBM compatible character set  
ESC+F+1  
ESC+F+2  
ESC+F+3  
§ The characters are formed using a 5x7 matrix. The first 127 entries in the font table are  
ASCII characters. Characters 0 through 31 are ASCII printer control characters, while 32  
through 127 are the 96 ASCII alpha numeric upper and lower case characters  
§ The alternate (extended) characters for each font type are from 128 through 255  
§ The printer defaults to Standard font on initial power up or upon receiving the CANCEL  
command (^X,18H,24).  
Character Size  
§ Four character sizes can be selected through the communication interface, by sending  
control characters to the printer  
Character Size  
Dot matrix size  
5x7  
Normal  
Expanded (Double Wide)  
Extended (Double Height)  
Large (double wide and double height)  
10x7  
5x14  
10x14  
Normal Character  
§ The Normal characters are formed using a 5x7 dot matrix. The printer defaults to 5x7  
matrix Normal character size upon initial power-up.  
Expanded Character  
§ Expanded size or double wide characters are formed by using 10x7 dot matrix.  
§ Expanded print is selected by sending the EXPAND character command (0E/14) to the  
printer, all succeeding characters are printed in Expanded form. Sending the EXPAND  
OFF character (0F/15) or Carriage Return resets the Expanded print to normal print.  
Extended Character  
§ The Extended or double height characters are formed by using a 5x14 dot matrix.  
§ Extended Print can be selected through the communication interface by sending the  
EXTEND command (1C/28) character. EXTEND (1D/29) or Carriage return resets the  
Extended print to normal print.  
Large Character  
Page 17  
§ The Large characters are formed by using a 10x14 dot matrix. Large character print is  
selected if both Expanded and Extended print is selected. To reset large print to normal  
print, Expanded and Extended prints must be disabled or Carriage return sent to printer.  
Dot Addressable Graphics  
§ The SERIES 2000i can print special symbols, graphs and characters if operated in the  
Dot Addressable Graphics mode.  
§ In the Dot Addressable Graphics mode of operation, the printer prints one dot line at a  
time. Each horizontal dot line is made out of (1x6) dot cells, and the total number of dot  
cells per line is the same as the maximum number of columns on the printer.  
§ Each dot in a (1x6) dot cell can be turned ON or OFF by sending specific ASCII  
characters.  
§ The graphics mode is invoked by sending ASCII characters 'ESC' (1B/27) followed by  
'G'. Dot line printing starts upon receiving enough dot cells to complete a dot line, or  
ASCII 'CR' (0DH) or ASCII 'LF' (0AH)  
§ The graphics mode is terminated by sending ASCII characters 'ESC', followed by 'A'.  
Graphic Character Set  
§ The graphic character set extends from the character '?'(3FH) to TILDA (7EH). Bits 1  
through 6 of the characters received are used to turn ON or OFF the dots in a dot cell.  
§ If a bit is set (=1), a dot is enabled, otherwise the dot is disabled.  
§ For example for ASCII '?' (3FH or 00111111B), bits 1 through 6 are set. Sending  
consecutive '?'s will form a one dot solid line across the paper.  
Page 18  
Section 6 ... S 2000T Character Sets  
Resident Character Sets  
§ The Series 2000T has two resident character sets, the standard international and IBM  
compatible character sets. For both resident character sets, the lower 128 bit values follow  
the ASCII standard. Characters 0 through 31 are reserved ASCII printer control  
characters, while 32 through 127, are the ASCII alpha numeric upper lower case  
characters. The extended characters are from 128 to 255.  
§ For the international character set, the upper 128 bit values code a collection of characters  
and symbols.  
§ The IBM compatible character set, the upper 128 bit values code a collection of block  
graphic characters and special characters for drawing frames and boxes.  
§ The printer defaults to the international character set on initial power up. To select an  
alternate character set the following command strings are recognized.

§ Both fonts are monospaced, meaning for each character pitch selected (cpi) all the  
characters are exactly the same width, making page layout easy to control. The MSP  
compatible dot matrix font are based on a single 6x16 font table. The printer modifies this  
table to yield various widths and weights.  
§ Four different font tables are used to generate the courier font typefaces. On initial power  
up, the printer defaults to 42 column, 21 cpi courier typeface. For the Courier normal  
characters, the individual lines or strokes of each character are finer, giving a more airy  
feel to the typeface. Courier bold characters have a heavier or thicker line width, putting  
more emphasis in the text.  
6-Bit Dot Addressable Graphics commands:  
§ The printer will operate in 6-Bit Dot Addressable Graphics mode on receiving the Esc-G  
graphic command. While in this mode the printer prints one dot line at a time on receipt  
of 64 graphic characters or LF command. The LF command advances the paper by one  
dot line.  
§ Each horizontal graphic dot is made from 1x6 dot cells; the total number of dot cells per  
line is 64, corresponding to the 384 total dots per line capacity. Each dot in a dot cell can  
be turned on or off by sending specific ASCII characters. For example, #F hex will  
energize all dots, while 40 hex de-energizes all the dots.  
Select 6 Bit Addressable Graphic Mode:

Section 7 ... Operating in MS-DOS World  
For proper operation of the S2000T printers in the DOS environment, the following are required:  
FOR SERIES 2000T - Serial Printer Version  
§ Use DOS print command to print, or Write Direct to printer port.  
§ Set the PC's communication baud using DOS MODE command: Printer and PC baud rate  
and parity have to match.  
Ÿ
MODE com1:19200,n,8,1  
§ Redirect PC's serial (COM) port to parallel (LPT)  
MODE lpt1:=com1:  
§ Set the printer port for infinite retry using the DOS MODE command.  
MODE LPT1:,,P  
Ÿ
Ÿ
FOR SERIES 2000T - IrDA Printer Version  
§ To operate the IrDA interface in MS-DOS environment, an IrDA device driver is  
required. IrDA.SYS device driver is available from Extech.  
§ Install the file IrDA.SYS to the boot fixed drive.  
§ Next, modify the CONFIG.SYS file to include IrDA.SYS as one of the device drivers.  
For example: DEVICE = C:\IrDA.SYS COM1 IRQ4 ADDR3F8 ; where C:\ is the path of  
where you copied IrDA.SYS to, COM1 is the comport you choose, IRQ4 is the interrupt  
request of that com port, and ADDR3F8 is the base address of that com port.  
§ Finally, modify the AUTOEXEC.BAT file to include a command to reroute one of the  
line printers to the com port, for example:  
Ÿ
MODE LPT1:=COM1:  
§ Re-boot DOS so that the modified CONFIG.SYS and AUTOEXEC.BAT take effect.  
From that point on, anything you send to the rerouted line printer will go through the  
IrDA.SYS driver.  
Operating in Windows  
§ To insure proper operation of the SERIES 2000 parallel version, in windows environment  
the following are required.  
§ Select Generic/text only printer driver.  
§ Use Windows printer manager.  
§ For the SERIES 2000 serial version, set the PC's serial port (COM1) baud rate and parity  
to match printer.  
§ Use printer Self-Test to verify baud rate and parity setting.  
Page 21  
Section 8 ... Supervised Mode Operation  
§ The S2000T printers can be operated in a supervised mode. A single byte supervision  
command <0x02> (^B), allows polling the status of the printer.  
§ The printer transmits the three types of status strings upon receiving the supervision  
request command byte:  
·
·
·
Print buffer status:  
Battery Voltage status:  
MCR status:  
<ESC> <B> <4 ASCII digits><CR><LF>  
<ESC> <V> <4 ASCII digits><CR><LF>  
<ESC> <M><4 ASCII digits><CR><LF>  
§ The four ASCII digits report the number of characters in print buffer, current battery  
voltage level and Magnetic Card Reader (MCR) status. These digits are in "converted  
hexadecimal" format. To reconvert these digits to hexadecimal form, subtract <0x30>  
from each digit received.  
§ In general, the printer can be polled as often as needed. The poll response is transmitted  
as one complete transaction with no XON/XOFF, ^D or AuxOff in the middle of  
response.  
§ The examples below illustrate the supervisory response strings.  
Print buffer status  
§ For Example if <0x04D2> characters are in the print buffer, the following string is  
returned upon receiving a <0x02> poll command.  
<0x1B> <0x42>  
<ESC> <B>  
<0x30> <0x34> <0x3D> <0x32>  
----<4 ASCII digits>----  
<0x0D> <0x0A>  
<CR> <LF>  
Magnetic card reader status  
§ For Example, if the following Magnetic card read command is issued (esc-M-9-9-1-CR-  
LF), the following is returned upon receiving a <0x02> poll command.  
<0x1B> <0x4D>  
<ESC> <M>  
<0x30> <0x39> <0x39> <0x31>  
<time out> <track>  
<0x0D> <0x0A>  
<CR> <LF>  
Page 22  
Printer battery level status  
§ For Example, if the printer battery voltage is at 6.58 volts the following battery status  
string is returned upon receiving a <0x02> poll command.  
<0x1B> <0x4D> <0x00> <0x36> <0x35> <0x38>  
<0x0D> <0x0A>  
§ The internal battery voltage can vary from 5.00 (depleted) to 7.25 (full charge) volts.  
Page 23  
Section 9 ... Auto Power Down Feature  
§ In order to conserve battery life the S2000T printer features a auto power down timer.  
The power down timer defaults to 20 seconds on initial power up.  
§ The auto power down timer can be set by sending recognized command string or disabled  
by activating the <RTS> input line or setting the auto power down timer to zero.  
§ The auto power down command string:  
ESC

§ The first two characters "ESC" and "M" are command header characters. The next two  
digits ASCII "01" through "99" sets the time-out in seconds, while the last two characters  
are the command terminator characters.  
§ Sending ESC-C resets the auto timer to initial power up default setting of 20 seconds.

6-Bit Dot Addressable Graphics  
The printer will operate in 6-Bit Dot Addressable Graphics mode on receiving the Esc-G graphic  
command. While in this mode the printer prints one dot line at a time on receipt of 64 graphic  
characters or LF command. The LF command advances the paper by one (0.25mm) dot line.  
Each horizontal graphic dot is made from 1x6 dot cells; the total number of dot cells per line is  
64, corresponding to the 384 total dots per line capacity. Each dot in a dot cell can be turned on  
or off by sending specific ASCII characters. For example, 0x3F hex will energize all dots, while  
0x40 hex de-energizes all the dots.

6-Bit Dot Addressable Graphics  
The printer will operate in 6-Bit Dot Addressable Graphics mode on receiving the Esc-G graphic  
command. While in this mode the printer prints one dot line at a time on receipt of 96 graphic  
characters or LF command. The LF command advances the paper by one (0.25mm) dot line.  
Each horizontal graphic dot is made from 1x6 dot cells; the total number of dot cells per line is  
96, corresponding to the 576 total dots per line capacity. Each dot in a dot cell can be turned on  
or off by sending specific ASCII characters. For example, 0x3F hex will energize all dots, while  
0x40 hex de-energizes all the dots.

Section 12 ... Magnetic Card Reader  
Introduction  
Ÿ An optional Magnetic Card Reader is available for the S2000T series printers. This  
option is designed to read Magnetic Cards conforming to ISO standards (ABA, IATA,  
MINTS and THRIFT), convert the encoded signals to ASCII format and transmit the  
information to the host computer or terminal.  
Ÿ Two Types of Magnetic Card Reader Heads are available. The part number, Model  
number and functional description of each type are summarized below.

Interfacing to the Magnetic Card Reader  
§ This section details the software steps required to access the Magnetic Card Reader from  
a computer or from a terminal.  
§ Select the printer  
§ The Host Selects the S2000T printer by activating the RTS input line or sending wake-up  
character to the printer.  
§ The Printer Sends the XON command to the Host to indicate ready to receive Command  
strings. The host has to wait for XON before proceeding.  
§ Select the Magnetic Card Reader  
Ÿ
The Host sends ASCII serial command string to enable the Magnetic Card Reader. The  
printer turns on the <READY> LED if the proper command string is received.  
§ Receive the ASCII Data Output from printer  
Ÿ
Once the magnetic card is swiped by the operator, the printer transmits in ASCII format  
<Track Data> or <Error Message>. A good read automatically turns off the reader. The  
printer turns on the red <ERROR> LED if an error is encountered.  
Page 42  
Recognized Magnetic Card command strings  
§ Six Magnetic Card command strings are recognized by the printer, these commands are  
summarized in the table below:  
Magnetic Card Command String  
ESC - M - nn - 1 - CR  
ESC - M - nn - 2 - CR  
ESC - M - nn - 3 - CR  
ESC - M - nn - 4 - CR  
ESC - M - nn - 5 - CR  
ESC - C  
Description  
Read Track1 only  
Read Track2 only  
Read Track3 only  
Read Track1 and Track2 simultaneously  
Read Track2 and Track3 simultaneously  
Cancel Read  
Turns off the <READY> LED  
(nn = ASCII "01" through "99" seconds)  
§ The command syntax is as follows:  
ESC n n Track #  
(1) ( 2 ) (3)  
§ Turn On the Card Reader  
The first two characters "ESC" "M" turn on the Card Reader.  
§ Set the Card Read Time-out  
M
CR  
(4)  
Ÿ
Ÿ
The next two digits "01" through "99" sets the time-out in seconds before the printer  
turns off the Card Reader. A good read automatically turns off the reader.  
§ Select Track number to read  
Ÿ
Ÿ
Ÿ
Ÿ
Ÿ
The Fifth character specifies the Track number's) to read.  
Sending "1", "2" or "3" enables read of single track 1, 2 or 3.  
Sending "4" enables simultaneous read of tracks 1 and 2.  
Sending "5" enables simultaneous read of tracks 2 and 3.  
There is currently no command to read tracks 1, 2 and 3 simultaneously.  
§
Terminate command string  
Ÿ
The S2000 waits for Carriage return character before start of the magnetic card read  
process.  
Track Data Output Format  
§ The <Track Data> retrieved from magnetic card is transmitted to the Host in ASCII  
format. The <Track Data> format is as follows:  
Ÿ
Ÿ
Ÿ
/1/ <TRACK 1 DATA> <CR> <LF>  
/2/ <TRACK 2 DATA> <CR> <LF>  
/3/ <TRACK 3 DATA> <CR> <LF>  
Page 43  
§ The first three characters (/,1,/) flag the track number. The track data follows the third  
character, CR-LF terminates the <Track Data> string.  
Read Error Messages  
§ All error messages are prefaced by <ESC><E> characters. Following these two characters  
is a comma, the error number in ASCII (01 through 99), another comma, English  
description of the error encountered and finally CR-LF terminating the <Error Message>  
string. The syntax is as follows:  
Ÿ
Ÿ
<ESC><E>, nn, Error text in ASCII, <CR><LF>  
Where nn is error number encountered.  
§ Nine (9) types of Read Error messages may be transmitted by the Mag card reader. The  
following messages terminated with CR-LF are returned by the firmware:  
Error #  
01  
Error Message Transmitted  
Parity Error  
02  
Checksum Error  
03  
End Sentinel Not Found  
Too Many Characters  
Time-out Expired  
04  
05  
06  
Invalid Character  
07  
Invalid Track Number  
Unsupported Track Selected  
Cancel Request  
08  
09  
Read Error Messages  
Error #  
Error Message Description  
01  
The Parity of the character read is opposite of the  
card default parity.  
02  
The Checksum calculated did not match the one on the  
card. The checksum is calculated by Exclusive-OR'ing  
all the valid data on the card including Begin Sentinel  
and End Sentinel, but excluding the checksum byte.  
03  
04  
End Sentinel must exist on all cards, Reader did not  
find the End Sentinel.  
The Maximum number of characters allowed for a track  
was exceeded. This may happen if End Sentinel is not  
found.  
05  
The command time-out has expired.  
Page 44  
06  
07  
08  
09  
The Track Reader Escape command string transmitted  
by Host contained an invalid character.  
Invalid Track Number is selected. Tracks "1", "2" or  
“3" can be selected.  
Unsupported Track is Selected. Tracks "1", "2" or  
"3" can be selected.  
"Cancel Request" error string is transmitted if Host  
cancels Magnetic card read in process.  
Magnetic Card Reader Operation in IrDA Mode  
§ The way we handle the magnetic card data is the same as for printing data. Esc-M is sent  
to the printer in the same way as any other data and the magnetic card reading data is sent  
back the same way (only that it is in the reverse direction).  
§ IrDA protocol has no knowledge of this at all, they are both "user data". Thus, at least in  
principle, there is no need to modify anything in the IrDA Stack.  
§ IrCOMM-3 wire raw is designed to deliver a single stream of "user data" in either  
direction. "User data" can be the ASCII code for "A", <CR>, Esc, or anything. In our  
case, "user data" happen to be Esc-M in one direction and magnetic card data in the  
other.  
§ IrLPT is almost identical to IrCOMM 3-wire raw, except that most people incorrectly  
assume that data flows in one direction only.  
§ Early printers were unidirectional; however, more are now bi-directional, like our Series  
2000.

Section 13 ... Extech IR-XMODEM Protocol  
§ This is a proposed protocol for bi-directional data transfer through an Infrared channel. The  
protocol is based on packet transfer utilizing checksum error detection. Format of the data  
packet is shown below:  
SOH (0x01)  
SEQ  
CSEQ  
...DATA [128 Bytes]...  
Checksum  
§
When powered on, the Extech printer will default to slave mode, requesting to receive  
packets (sending a NAK character every 10 seconds). After receiving a magnetic card reader  
request and the master closes the connection, the Extech printer switches to master mode. In  
master mode the printer waits to receive a transmission request (NAK).  
Summary of Extech IR-XMODEM transmission procedure:

Testing Power and Charging Circuits for MPP III Printer  
Test all printers, before returning to Extech, using the following procedure. This will ensure the  
fault is with the printer and not some other part of your system.  
§ Install a fully charged battery (measuring 5.45 VDC)  
§
To ensure a fully charged battery, we recommend you purchase a battery  
charger from us (Part # 767500, cost $150.00). The battery charger trickle  
charges 4 batteries at a time.  
§ Press <OFF> switch and wait until all lights are off  
§ Press and hold the <FEED> switch and then insert AC adapter plug into  
printer. The printer will print a self test receipt (similar to AC test strip below)  
Ÿ
To test the AC adapter use a multimeter and measure output (output  
must be > 12.5V)!  
Ÿ
If the amber charge light goes on the battery is not fully charged, but  
charge circuit is OK  
If the receipt is printed, AC power is OK  
§ Release <FEED> and remove the AC adapter plug from the printer.  
§ Press <FEED> switch and while continuing to press <FEED>, press <ON>.  
The printer will print a self test receipt (similar to DC test strip below).  
Release <FEED> and <ON> when receipt starts to print  
If a self test receipt is generated, DC power is OK  
§ Press <OFF> and wait until all lights are off  
§ Plug AC adapter into printer. Press <ON>; the green ON-LINE light  
illuminates and after 20 seconds the red STATUS light should flash, the  
green AC-ON light is illuminated and the ON-LINE light goes off. After 20  
seconds all lights go off  
Ÿ
If the CHARGE light is on, this will continue on through this test  
§ Remove battery and replace it with a low power battery (around 5.1  
VDC)  
§ Insert AC adapter plug into printer  
Page 49  
If the amber CHARGE light comes on indicating charge  
circuit is OK.
