GENERAL PRECA UTIONS FOR INSTALLATION/SERVICING/
MAINTENANCE
1. When installing the Large Capacity Feeder KD-1010 to the Copier, be sure to follow the instructions
described in the “Unpacking/Set-Up Procedure for the KD-1010” booklet which comes with each unit of
the KD-1010.
2. The KD-1010 should be installed by an authorized/qualified person.
3. When transporting/installing the KD-1010, employ two persons and be sure to use the positions as
indicated below . The KD-1010 is f airly heavy and weights appro ximately 23 kg (51 lb), therefore pa y full
attention when handling it.
4. Before starting installation, servicing or maintenance work, be sure to turn off and unplug the copier
first.
5. The KD-1010 is supplied with power from the copier , requiring no additional power source.
6. The KD-1010 should be grounded to the specified positions on the machine frame.
7. When servicing or maintaining the KD-1010, be careful about the rotating or operating sections such as
gears, pulleys, sprockets, cams, belts, etc.
8. When parts are disassembled, reassembly is basically the rev erse of disassembly unless otherwise
noted in this manual or other related documents. Be careful not to reassemble small parts such as
screws, washers, pins, E-rings, toothed washers to the wrong places.
9. Basically, the machine should not be operated with any parts removed or disassemb led.
10. Delicate parts for preventing safety hazard problems (such as thermofuses, door switches sensors,
etc. if any) should be handled/installed/adjusted correctly.
11. 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.
12. Use suitable measuring instruments and tools.
13. 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 copier and make sure that
there is no uninsulated objects in the vicinity.
14. For the recov ery and disposal of used KD-1010, consumable parts and packing materials, it is recommended that the relevant local regulations/rules should be followed.

3. GENERAL OPERATION
3.1 Description of Operation
[A] From power ON to standby
(1) When the copier is turned ON, power is also supplied to the feeding unit to start the pre-running
operation. The tray-up motor (M2) starts to rotate forw ard and raises the tray. The tr ay-up motor (M2) is
turned OFF when the tray turns ON the tray-up sensor (S3), then the tray is stopped. At this time, it is
judged that there is paper in the feeding side cassette when the feeding side empty sensor (S7) is ON.
On the other hand, the absence of paper in the feeding side cassette is assumed when the sensor (S7)
is OFF, and the standby side empty sensor (S8) is subsequently checked. When the standby side
empty sensor (S8) is OFF, that means that paper is absent in the standby side cassette, and it is
therefore assumed that there is no paper in the LCF. When the standby side empty sensor (S8) is ON,
the paper in the standby side cassette is mov ed to the f eeding side cassette . The tray-up motor (M2)
is rotated in rev erse and lowers the tra y of the feeding side . The lowered tra y turns ON the tray bottom
sensor (S4), and the tray-up motor (M2) is turned OFF to stop the tray. The end fence solenoid and
pickup solenoid are then turned ON. The end fence motor (M3) rotates forward and the paper in the
standby side cassette is mov ed onto the tray of the f eeding side. The end fence motor (M3) is stopped
for a second when the end fence stop position sensor (S5) is turned ON, and the motor (M3) immediately starts to rotate in reverse to return the end fence to the position where the home position sensor
(S6) is turned ON. When the returning operation is started, the end fence solenoid and pickup solenoid
are turned OFF, and the tray-up motor (M2) is rotated forward to r aise the tra y . The tr ay-up motor (M2)
is turned OFF when the tray being raised turns ON the tray-up sensor (S3) and stops the tr a y. At this
time, the presence of paper is judged when the feeding side empty sensor (S7) is ON.
(2 ) If the power is turned ON when the cassette has been removed, the tray-up motor for that cassette is
not turned ON. The tray is raised as soon as the cassette is installed, and it detects if there is paper
in the cassette.
(3) If either of the feed sensor (S2) is ON (there is paper in the transportation path) when the power is
turned ON, that means a paper jam has occurred and the operation is disabled until the paper is
removed.
October 2000 © TOSHIBA TEC 3 - 1 KD-1010 GENERAL OPERATION
[B] Standby status
(1 ) T ra ys detect the paper as described abov e, and the copier goes into the standb y status .
(2 ) The tray goes down automatically when the cassette is removed and is raised as soon as the cassette
is reinstalled it then checks if there is paper in the cassette.
[C] From the start to the end of copying
(1 ) The main motor of the copier is turned ON when the START ke y is pressed. The LCF transport motor
(M1) are turned ON to drive.
(2 ) When the copier judges that the LCF is ready f or f eeding paper , it turns ON the feed clutch (C2) of the
selected cassette. This clutch drives the pic kup roller and feed roller to feed paper from the tra y.
(3 ) About 0.02 sec (DP4500/3500: 0.05 sec), after the feeding started transport clutch (C1) are turned ON
to drive the transport roller.
(4 ) The leading edge of the paper turns the feed sensor (S2) ON. These are located right ne xt to the e xit
side of the selected cassette. The feed clutch (C2) is turned OFF and feeding from the cassette is
completed.
(5 ) The paper is tr ansported to the copier by the LCF transport roller. If the trailing edge of the pre viously
sent sheet still remains at the feed sensor when the leading edge of the paper reaches the feed sensor
(S2), the transport clutch (C1) is turned OFF to stop the transport of the paper.
(6 ) The trailing edge of the paper turns the feed sensor (S2) OFF. These are located right next to the exit
side of the selected cassette. LCF then becomes ready for feeding the next sheet of paper, and the
procedures (2) to (5) are repeated.
(7) When the copying operation is completed, the main motor, LCF transport motor (M1) and transport
clutch (C1) are turned OFF and the transport roller is stopped.
KD-1010 GENERAL OPERATION 3 - 2 October 2000 © TOSHIBA TEC
3.2 Error Detection
[A] Jam detection
(1 ) A paper jam (E19, E33, E36) [DP4500/3500: (E19, E3C, E3D, E3E)] occurs in the following cases.
a. Feed sensor (S2) is not turned ON within 0.5 seconds after the feeding is started.
b . The leading edge of the paper does not pass the feed sensor (S2) in the transport path within a fixed
time.
(2 ) Open the side co ver of the paper feeder and remo ve all the paper remaining on the transport path and
close the side cover to clear the jammed paper. If either of the f eed sensors (S2) 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 canceled.
(3 ) When a paper jam occurs in the paper feeder during multiple copying, the sheet that was fed before the
jam is copied normally .
[B] Call Service
(1 ) When the tray-up sensor (S3) is not turned ON even through 8 seconds (DP4500/3500: 10 seconds)
have passed since the tr ay started to be raised, it is assumed that the cassette cannot be used (there
is no paper) and the corresponding message is displayed on the control panel.
(2) When the tray bottom sensor (S4) is not turned ON even through 8 seconds (DP4500/3500: 10 seconds)
have passed since the tray started to be lowered, it is assumed that the cassette cannot be used
(there is no paper) and the corresponding message is displayed on the control panel.
(3) When the end fence stop position sensor (S5) is not turned ON even through 8 (DP4500/3500: 5
seconds) seconds have passed since the end fence started to move the paper in the standby side
cassette, it is assumed that the cassette cannot be used (there is no paper) and the corresponding
message is displayed on the control panel.
(4) When the end fence home position sensor (S6) is not turned ON even through 8 seconds (DP4500/
3500: 5 seconds) ha ve passed since the end f ence started to move the paper in the standby side , it is
assumed that the cassette cannot be used (there is no paper) and the corresponding message is
displayed on the control panel.
(5 ) The states (1) to (4) are cleared by removing the cassette.
