Tray 3 and 4 Assembly
Run the following components:
• Open the left hand door. Enter dC330 code 08-045 tray 3 and 4 transport motor, to run the
tray 3 and 4 transport roll, PL 8.30 Item 18.
• Pull out tray 3 and let the tray drop, then push the tray back in. Enter dC330 code 07-030
Tray 3 elevator motor, to elevate tray 3, PL 7.20 Item 1.
• Pull out tray 4 and let the tray drop, then push the tray back in. Enter dC330 code 07-040
Tray 4 elevator motor to elevate tray 4, PL 7.20 Item 1.
Possible causes and potential solutions are:
• Knocking noise No drive or a knocking noise from the tray 3 and 4 transport motor.
Possible causes are:
– The tray 3 and 4 transport motor.
– Worn or stretched elevator cables.
– Worn or stretched elevator cables.
Solution:
– Check the drive belt and gears, PL 8.30 Item 8.
– Adjust and install new components as necessary, PL 7.15.
– Check that the paper trays are correctly position and that the tray moves freely
inside the tray assembly.
– Install new components as necessary, PL 7.15.
Tray 5 Assembly
Run the components as follows:
• Open the tray 5 door to lower the elevator.
• Close the door or actuate the interlock.
• Enter the dC330 code 07-373 to drive the tray up.
• Enter the dC330 code 07-374 to drive the tray down.
• Enter the dC330 code 08-046 to operate the tray 5 transport motor, PL 8.40 Item 2.
• Enter the dC330 code 08-117 to operate the tray 5 feed motor, PL 8.40 Item 3.
Check the associated belts, rollers, bearings, sensors and encoders for possible noise
sources.
Xerographics
Run the following components:
• Enter dC330 code 09-010 P/R motor, to run the photoreceptor drive motor, (32-55 ppm)
PL 4.15 Item 17 or (65-87 ppm) PL 4.10 Item 17.
• Enter dC330 code 09-071 Scorotron Cleaner Motor Forward or 09-072 scorotron cleaner
motor Reverse, to run the scorotron cleaner motor.
Possible causes and potential solutions are:
• A high pitched noise when the corotron is switched on.
Possible causes are:
– The detack corotron.
Solution:
– None, this is normal behavior.
• A clicking noise from the Xerographic module.
WorkCentre 5687 Family
Possible causes are:
– The scorotron cleaning mechanism. A clicking noise is made when the scorotron
cleaning brush reaches the end of its travel.
Solution:
– None, this is normal behavior. If the scorotron cleaning mechanism is the cause of
the noise, inform the customer.
• Knocking or clicking noise.
Possible causes are:
– Xerographic module drive gear is not correctly engaged, PL 9.20 Item 2.
– Developer module drive gear is not correctly engaged, PL 9.15 Item 2.
– Cooling fan blades catching on a harness, component or cover.
Solution:
– Remove the xerographic module. Re-install the module.
– Remove and lubricate the developer module support pins, REP 9.2. Refer to ADJ
4.1 Machine Lubrication.
– Ensure that the fan is secured correctly and the area around the fan is clear.
– Install a new fan:
Cooling fan, PL 3.10 Item 2.
Ozone fan, PL 9.25 Item 1.
Photoreceptor fan assembly, PL 9.25 Item 6.
Fuser
Possible causes and potential solutions are:
• Grinding noise.
Possible causes are:
– The fuser web motor not turning the fuser web, causing excessive loading on the
fuser drives. This will also cause toner contamination on the stripper fingers and
paper jams in the inverter.
– The fuser web drive dog, 32-55 ppm PL 10.8 Item 2 or 65-87 ppm PL 10.10 Item 2.
Solution:
– Go to 10A Fuser Web Motor RAP.
NOTE: Do not change the fuser module, because of the appearance of wrinkles on
the pressure roll. This is normal for the pressure roll, caused by the conductive
sleeve that stretches as the silicon rubber base of the roll expands. The pressure
rolls are more wrinkled due to the higher run temperatures on the 65-87 ppm
machines.
LCSS 1K
Run the following components:
• Enter dC330 code 11-000 Transport Motor 1, to run the entry transport rolls, PL 11.110
Item 2 and PL 11.110 Item 9, PL 11.110 Item 6.
• Enter dC330 code 11-001 Transport Motor 2, to run the entry rolls, PL 11.120 Item 13.
• Enter dC330 code 11-024 Paddle Wheel Motor Run, rotates the paddle wheel, PL 11.104
Item 4.
• Enter dC330 code 11-009 Tamp Mot Cycle, cycles the front and rear tampers, PL 11.112
Item 1.
