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.

3. GENERAL OPERATION

3.1 Driving System and Feeding Operation

The Paper Feed Pedestal (PFP) mainly consists of the drawer, pickup roller, feed roller, separation roller, transport roller, and drive systems for these components.

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

• Drawer tray system This system raises and lowers the tray.

GENERAL OPERATION

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.

(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.

3

(2) The state (1) is cleared by opening the drawer and solving the problems.

Note:

Make sure that the grease does not adhere to the roller surface. Wipe it off with alcohol if adhered.

* c2. Drive gears in the paper feeding section (teeth of gears and shafts)

Apply some white grease (Molykote EM-30L) to the teeth of gears and shafts of the drive gears.

Note:

Make sure that oil is not running over or scattered around as the gear is rotated coming into the clutch after applying Molykote to the gear which is located near the clutch. The quantity of Molykote should be smaller than that to be applied to the other parts.
