GENERAL PRECAUTIONS FOR INSTALLATION/SERVICE/ MAINTENANCE FOR LARGE CAPACITY FEEDER MP-4003
1. When installing the Large Capacity Feeder MP-4003 to the Copier, be sure to follow the instructions
described in the “Unpacking/Set-Up Procedure for the MP-4003” booklet which comes with each
unit of the MP-4003.
2. Installed only by an authorized/qualified person.
3. When transporting/installing the MP-4003, employ two persons. The MP-4003 is fairly heavy and
weights approximately 40 kg (89 lb), therefore pay full attention when handling it.
4. Before starting installation, servicing or maintenance work, be sure to turn off and unplug the
copier first.
5. Supplied with power from the copier, requiring no additional power source.
6. Grounded to the specified positions on the machine frame.
7. When serving or maintaining, 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 reverse 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 disassembled.
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 recovery and disposal of used the large capacity feeder, consumable parts, packing materials,
used batteries, and RAM-ICs including litium batteries, it is recommended that the relevant local
regulations/rules.

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 feed unit from the copier to start the pre-
running operation. The tray motor (M2) starts to rotate forward to lift the tray.
The tray motor (M2) stopped rotating and lifting the tray when the tray has been lifted and the tray-up
sensor (S2) has been turned ON (H: Sensor light path blocked by the actuator sensor). Papers are
assessed to be present when the empty sensor (S1) is turned ON (L:Passing the sensor light path )
while they are assessed to be absent when the empty sensor (S1) is turned OFF (H: Sensor light path
blocked).
(2) When the LCF is not being installed to the copier (LCF set sensor (S7): OFF) or when the drawer is
being pulled out (Tray sensor (S5): OFF), the tray lifting operation is not carried out. In this case, the
tray starts to be lifted and the same operation which is until the detection of the paper presense or
absense is carried out when it is installed to the copier and the drawer is inserted.
(3) When the feed sensor (S3) is turned ON (L: Passing the sensor light path), that is, when the paper is
remaining at the transport path, the LCF detects it as a paper jam and cannot operate.
[B] Standby state
(1) When a paper is detected to be present by the above-described operation, the LCF gets into a standby
state.
(2) When the tray unit is pulled out, the tray is automatically lowered because of its structure, and when it
is inserted once again, it is lifted.
[C] Feeding/Transporting operation from the start to the finish of the printing
(1) The [START] key is pressed when the copier decides that the feeding from the the LCF. Then, the
transport motor (M1) starts to drive after the feed motor of the copier has been turned ON.
(2) The feed clutch (CL2) is turned ON and pickup and feed rollers start to drive to feed a paper from the
tray.
(3) After the feeding starts, the transport clutch (CL1) is turned ON and the transport roller starts to drive
to transport the paper.
(4) When the leading edge of the paper has turned ON the feed sensor (S3), the feed clutch (CL2) is turned
OFF and stops the feeding operation. The paper transported by the transport roller is sent to the copier
side, where it is transported by the feed unit.
(5) When a specified time has passed after the trailing edge of the paper turned OFF the feed sensor (S3),
next paper can be fed.
(6) When carrying out a continuous printing, the above steps from (2) to (5) are repeated as many papers
as printed.
(7) When the printing has been finished, the feed motor of the copier stops rotating and the transport motor
(M1) is turned OFF to finish the feeding/transporting operation.
JUNE 2002 © TOSHIBA TEC 3 - 1 MP-4003 GENERAL OPERATION
[D] Tray operation during printing
(1) When 10~20 sheet of paper have been fed from the tray, the pickup roller is lowered down to a
specified height. The tay-up sensor (S2) detects this and the tray motor (M2) rotates forward to lift
the tray.
3. 2 Error Detection
[A] Jam detection
In the following cases, the feed jam takes place.
(1) When the feed sensor (S3) is not turned ON in a specified time after the feeding has started.
(2) When each transport sensor of the copier does not operate (ON/OFF) in a specified time after the
feeding has started at the copier side.
[B] Call for service
(1) When the tray-up sensor (S2) is not turned ON in a specified time after the tray has started to be lifted.
