GENERAL PRECAUTIONS FOR INSTALLATION/SERVICING/
MAINTENANCE
The installation and service shall be done by a qualified service technician.
1. When installing the Paper Feed Pedestal KD-1025 to the equipment, be sure to follow the
instructions described in the "Unpacking/Set-Up Procedure for the KD-1025" booklet which comes
with each unit of the KD-1025.
2. The KD-1025 should be installed by an authorized/qualified person.
3. When transporting/installing KD-1025, employ two persons and be sure to use the positions as
indicated below.
KD-1025 is fairly heavy and weights approximately 21 kg (46.3 lb.), therefore pay full attention when
handling it.
4. Before starting installation, servicing or maintenance work, be sure to turn OFF and unplug the
equipment first.
5. Be sure to fix and plug in the power cable securely after the installation so that no one trips over it.
6. The equipment shall be installed near the socket outlet and shall be accessible.
7. Unplug the power cable and clean the area around the prongs of the plug and socket outlet once a
year or more. A fire may occur when dust lies on this area.
8. The KD-1025 is supplied with power from the equipment, requiring no additional power source.
9. The KD-1025 should be grounded to the specified positions on the machine frame.
10.When servicing or maintaining the KD-1025, be careful about the rotating or operating sections such
as gears, pulleys, sprockets, cams, belts, etc.
11.When servicing the machines with the power turned ON, be sure not to touch live sections and
rotating/operating sections.
12.When parts are disassembled, reassembly is basically the reverse of disassembly unless otherwise
noted in this manual or other related materials. Be careful not to reassemble small parts such as
screws, washers, pins, E-rings, toothed washers to the wrong places.
13.Basically, the machine should not be operated with any parts removed or disassembled.
14.Delicate parts for preventing safety hazard problems (such as thermofuses, door switches sensors,
etc. if any) should be handled/installed/adjusted correctly.
15.Use suitable measuring instruments and tools.

16.During servicing or maintenance work, be sure to check the nameplate and other cautionary labels
(if any) to see if they are clean and firmly stuck. If not, take appropriate actions.
17.The PC board must be stored in an anti-electrostatic bag and handled carefully using a wristband,
because the ICs on it may be damaged due to static electricity.
Caution:
Before using the wrist band, pull out the power cord plug of the equipment and
make sure that there is no uninsulated objects in the vicinity.
18.For the recovery and disposal of used the Paper Feed Pedestal, consumable parts, packing
materials, follow the relevant local regulations/rules.
19.Return the equipment to the original state and check the operation when the service is finished.

Feeding/Transport system
The PFP motor drives the pickup roller, feed roller, and transport roller which are located in the
feeding area.

GENERAL OPERATION

Download from Www.Somanuals.com. All Manuals Search And Download.
3.2 Description of Operations
[A] From power ON to ready
(1) When the equipment is turned ON, the power is also supplied to the feeder unit. And when the
power is supplied, the feeder unit detects and judges the clock frequency output from the LGC
board on the equipment to control transport speed of the unit.
(2) After that, the tray-up motor (M2)/(M3) is turned ON to raise the corresponding tray. When the
tray-up sensor (S4)/(S5) is turned ON correspondingly, the tray-up motor (M2)/(M3) is turned
OFF to stop the tray. If the empty sensor (S6)/(S7) is OFF (H) at this time, it is judged that there
is no paper in the drawer. If the empty sensor is ON (L), it is assumed that there is paper in the
drawer, and the tray stays in the raised position until the drawer is pulled out.
(3) If the power is turned ON when the drawer has been pulled out, the tray-up motor for that drawer
is not turned ON. The tray is raised as soon as the drawer is installed, and it detects if there is
paper in the drawer.
(4) If either of the drawer feed sensors (S2), (S3) is ON (there is paper in the transport path) when
the power is turned ON, that means paper jam has occurred and operation is disabled until the
paper is removed.
[B] Ready status
(1) Trays detect the paper as described above, and the equipment goes into ready status.
(2) The tray goes down automatically when the drawer is removed and it is raised as soon as the
drawer is installed again and checks if there is paper in the drawer.
[C] From the start to the end of copying
(1) When the [START] button is pressed, the feed/transport and exit motors of the equipment and
the PFP motor (M1) are turned ON at the same time.
(2) When the equipment judges that PFP is ready for feeding paper, it turns ON the feed clutch
(CLT2)/(CLT3) of the selected drawer. This clutches drive the pickup roller and feed roller to feed
paper from the tray.
(3) When the drawer feed sensor (S2)/(S3) comes ON, the transport clutch (CLT1) is turned ON to
drive the PFP transport roller.
(4) A fixed time after the drawer feed sensor (S2)/(S3) comes ON, the feed clutch (CLT2)/(CLT3) is
turned OFF and feeding from the drawer is completed.
(5) The paper is transported to the equipment by the PFP transport roller. A fixed time after the
leading edge of the paper reaches the drawer feed sensor (S2), if the trailing edge of the
previously sent sheet still remains at the copier feed sensor, the transport clutch (CLT1) is turned
OFF to stop the transport of the paper.
(6) A fixed time after the paper turns the resist clutch ON, PFP becomes ready for feeding the next
sheet of paper, and the procedures (1) to (5) are repeated.
(7) When the copying operation is completed, the feed/transport motor, exit motor, PFP motor (M1),
and transport clutch(CLT1) are turned OFF and the transport roller is stopped.

3.3 Error Detection
[A] Jam detection
(1) Paper jams (E150), (E160) and (E300 to E360) occur in the following cases.
•
Feed sensor (S2)/(S3) is not turned ON within a specified period of time after the feeding is
started.
•
The leading edge of the paper does not pass the feed sensor (S2)/(S3) in the transport path
within a specified period of time.
3
(2) Open the side cover of the PFP and remove all the paper remaining on the transport path and
close the side cover to clear the paper jam. If either of the drawer feed sensors (S2)/(S3) is still
ON when the side cover is closed, it is determined that there is still paper on the transport path
and the paper jam status is not cleared.
(3) When a paper jam occurs in the PFP during continuous copying, the paper that was fed before
the jam is copied normally.
[B] Call for Service
(1) The tray is raised when the power is turned ON or the drawer is inserted or pulled out. If the tray-
up sensor (S4)/(S5) is not turned ON within a specified period of time after the tray has started to
raise, a message that the selected drawer cannot be used is displayed on the control panel.
(2) The state (1) is cleared by opening the drawer and solving the problems.
