1. General information  
The Lexmark™ 4200 Series All-In-One (4413-XXX) is a letter quality  
print, fax, copy, and scan machine. It is a standalone color/mono  
copier and fax. The printhead uses small heater plates and nozzles  
to control ink flow and the formation of characters on the print media.  
The printhead assembly and ink supply are combined into a single  
unit. Print cartridges are available as a customer replaceable supply  
item. Dual printheads provide color and true black printing without  
changing printheads. The number and size of inkjets or nozzles, in  
the printhead, determines the overall quality and capability of the  
printer. The black cartridge has a total of 208 nozzles and installs on  
the right. The color cartridge has a total of 192 nozzles and installs  
on the left. The printer is capable of printing in both directions from  
either cartridge.

Maintenance station service check  
The maintenance station has three functions:  
1. Wipes the printhead nozzles to clean them of dirt.  
2. Provides a place for printheads to fire all nozzles, keeping them  
clear prior to printing.  
3. Seals the printhead when it is not being used to prevent the  
nozzles from drying.

Maintenance  
Station Assembly  
As the carrier moves to the right over the  
maintenance station, a slot on the bottom of the  
carrier engages a tab on the sled of the  
maintenance station causing the cap to rise and  
seal the printhead. Carrier movement to the left  
uncaps the printhead. The wiper cleans the  
printhead nozzles as the carrier leaves the  
maintenance station. The wiper cleans the  
printhead only when the carrier is moving to the  
left. Do not wipe the printhead nozzles when the  
carrier is moving to the right. After the cleaning  
operation is complete, a tab on the maintenance  
station engages a tab on the carrier, causing the  
wiper to lower.  
Check the maintenance station for worn or broken  
parts. Replace if needed. Go to the “Maintenance  
station removal” on page 4-17.  
Worn wipers cause degraded print quality just after  
a maintenance cleaning. Check for loose or worn  
wipers.  
Worn caps cause the printhead nozzles to dry and  
clog. Check for loose or worn caps.

3. Diagnostic aids  
Theory of mechanism  
Scanner mechanism  
The scanner mechanism consists of components which feed, scan,  
and eject the documents that are to be copied or transmitted to a  
remote facsimile unit. These components and their functions are  
explained below.  
Drive feed roller assembly  
The drive feed roller assembly, consisting of various rollers, rubber  
pad, and springs, automatically separates and feeds the pages of a  
document over the scanning area and stacks them on the document  
exit tray.  
Documents up to 15 pages can be placed in the drive feed roller  
assembly for scanning. The leading edge of the document moves  
the document detect sensor lever when the operator slides the stack  
into the drive feed roller assembly. The scan motor starts to rotate  
when the document detect sensor detects the leading edge of the  
document. The roller feeds the first page of the document into the  
feeder.  
The scan motor stops when the leading edge of the page actuates  
the document scan sensor. The page is now in the scan position.  
The drive feed roller assembly rubber pad prevents multiple sheets  
from being fed. A spring provides force that the pad places on the  
document pages for proper separation.  
The scan motor is turned on when the machine is ready to scan the  
document and drives the feed roller at a speed determined by the  
resolution selected. The scan motor stops after a set period of time  
when the trailing edge of the page releases the document scan  
sensor. If another page is detected as the trailing edge of the page  
releases the document scan sensor, the next page feeds to the scan  
position. The exit roller pushes the page out onto the document exit  
tray where it is stacked.  
Diagnostic aids 3-1  
                 
4413-XXX  
Contact Image Sensor (CIS)  
The contact image sensor unit consist of LEDs, rod lens array, and a  
photo sensor. The LEDs illuminate the document to be scanned  
when the leading edge is detected by the document scan sensor.  
The LEDs turn off when the document exits the scanner mechanism.  
The LEDs illuminate the document to obtain an image from the  
document through the rod lens array, where the image is translated  
into voltage levels.  
Document sensors  
There are two document sensors in the scanner mechanism; the  
document detect and the document scan sensor. The document  
detect sensor, detects whether or not a document is loaded, and the  
document scan sensor detects the scan position of the document.  
The scanner mechanism consists of components which feed, scan,  
and eject the documents that are to be copied or transmitted to a  
remote facsimile unit.

4. Repair information  
This chapter explains how to make adjustments to the printer and  
how to remove defective parts.  
Note: Read the following before handling electronic parts.  
Handling ESD-sensitive parts  
Many electronic products use parts that are known to be sensitive to  
electrostatic discharge (ESD). To prevent damage to ESD-sensitive  
parts, follow the instructions below in addition to all the usual  
precautions, such as turning off power before removing logic boards:  
• Keep the ESD-sensitive part in its original shipping container (a  
special “ESD bag”) until you are ready to install the part into the  
machine.  
• Make the least-possible movements with your body to prevent  
an increase of static electricity from clothing fibers, carpets, and  
furniture.  
• Put the ESD wrist strap on your wrist. Connect the wrist band to  
the system ground point. This discharges any static electricity in  
your body to the machine.  
• Hold the ESD-sensitive part by its edge; do not touch its pins. If  
you are removing a pluggable module, use the correct tool.  
• Do not place the ESD-sensitive part on the machine cover or on  
a metal table; if you need to put down the ESD-sensitive part for  
any reason, first put it into its special bag.  
• Machine covers and metal tables are electrical grounds. They  
increase the risk of damage because they make a discharge  
path from your body through the ESD-sensitive part. (Large  
metal objects can be discharge paths without being grounded.)  
• Prevent ESD-sensitive parts from being accidentally touched by  
other personnel. Install machine covers when you are not  
working on the machine, and do not put unprotected ESD-  
sensitive parts on a table.  
• If possible, keep all ESD-sensitive parts in a grounded metal  
cabinet (case).  
• Be extra careful in working with ESD-sensitive parts when cold  
weather heating is used because low humidity increases static  
electricity.  
Repair information 4-1

Adjustments  
The user is directed, in the Printer Control program, to perform the  
bidirectional alignment adjustments after replacing a print cartridge.  
Removal procedures  
The following procedures are arranged according to the name of the  
printer part discussed.  
CAUTION: Unplug the power cord before removing any parts.  
Releasing plastic latches  
Many of the parts are held in place with plastic latches. The latches  
break easily; release them carefully. To remove such parts, press the  
hook end of the latch away from the part to which it is latched.  
4-2 Service Manual  
           
4413-XXX  
Removals  
General precautions on removals  
When you disassemble and reassemble components, use extreme  
caution. The close proximity of cables to moving parts makes proper  
routing a must. If components are removed or replaced, any cables  
disturbed must be replaced as close as possible to their original  
positions. Before removing any component from the machine, note  
the cable routing.  
When servicing the machine:  
• Check to verify that documents are not stored in memory.  
• Move the printer cartridge to far right to cap the nozzle.  
• Unplug the power cord.  
• Use a flat and clean surface.  
• Replace only with authorized components.  
• Do not force plastic-material components.  
• Make sure all components are in their proper position.
