J-110 Mis-Registration In Stapled Sets And Non-Stapled Sets Rap - Xerox WorkCentre 5687 Series Service Manual

11J-110 Mis-Registration in Stapled Sets and Non-Stapled
Sets RAP
Use this RAP to identify and correct the causes of mis-registration in stapled sets, resulting in
staples missing some sheets in the set, or poorly registered non-stapled sets.
WARNING
Take care not to topple the LCSS.
The LCSS is unstable when un-docked from the machine.
Do not show the customer how to un-dock the LCSS.
Procedure
WARNING
Switch off the electricity to the machine, GP 14. Disconnect the power cord. Electricity
can cause death or injury. Moving parts can cause injury.
The most likely cause of mis-registration is paper condition and/or damage such as curl, wrin-
kle, creases, dog ears, etc.
Curl, wrinkle and creases are probably caused in the IOT, go to IQ1 Image Quality Entry RAP.
For other copy/print damage and dog ears, go to the 11H-110 Copy Damage in the 2K LCSS
RAP.
Check the following:
• Check that bin 1 is seated correctly and the bin 1 alignment clip is in position, PL 11.2
Item 13.
• Turn over the paper stack in the tray in use.
• Use a new ream of paper in the tray in use.
• Paper type especially recycled paper can lead to registration problems. Try changing to a
different brand or type of paper.
• Ensure that the guides in the paper trays are correctly set and reported on the UI for the
paper size loaded.
• Check that paper type is set correctly. If heavyweight paper is used but not set in the UI,
the compiler capacity can be exceeded.
• Check for obstructions in the compiler.
• Ensure that the paddle roll operates correctly and that the paddles are not damaged. The
paddles should park completely inside the top section of the compiler, with the shorter
paddle in a vertical position. If all of the paddles are out of position, check the paddle roll
position sensor, PL 11.8 Item 11, the flag, PL 11.8 Item 7 and the paddle motor assembly,
PL 11.8 Item 10. If only one paddle is mis-aligned with the others, it can be re-positioned
by hand (they are not bonded to the shaft).
• Ensure that the tampers operate correctly, i.e. are not stalling or losing position during the
job. Inspect the tampers for damage, if necessary install new parts. PL 11.16.
• Inspect the bin 1 entry nips for roll damage. The idlers should be held against the rubber
driving rolls and they should be free to rotate within their support springs. If necessary,
install new parts, PL 11.23.
• Inspect the four spring loaded guides on the output cover, PL 11.2 Item 7. Ensure that
they are correctly located and are free to move up and down.

11K-110 2K LCSS Poor Stacking RAP
Use this RAP to find the cause of poor stacking in the 2K LCSS.
Procedure
Check the following;
• Look for sets that are not dropping back fully in bin 1 and therefore not operating the bin 1
level sensors:
– Large paper sizes should not be stacked on top of small paper sizes.
– Ensure that the paper stack in each paper tray has been fanned.
– Turn over the paper stack in each paper tray.
– Ensure that all paper or other copy stock being used is within the size and weight
specifications. Refer to GP 20 Paper and Media Size Specifications.
– Try using a fresh ream of paper.
– Ensure that the edge guides of all paper trays are adjusted correctly for the paper
size and that the trays are fully closed.
– Check that bin 1 is seated correctly and the bin 1 alignment clip is in position, PL
11.2 Item 13.
• Labels must not be fed to bin 1, but to bin 0 only.
• It is recommended that transparencies are fed to bin 0 whenever possible.
• Check that bin 1 is level front to back, if necessary perform ADJ 11.1-110 2K LCSS Bin 1
Level.
• Check that the bin 1 upper level sensor,Q11-332 and the bin 1 lower level sensor, Q11-
333 are working correctly. Refer to the 11-030-110, 11-334-110, 11-335-110, 11-336-110
Bin 1 Movement Failure RAP.
• Check the operation of the front and rear tampers. Refer to 11-005-110, 11-006-110, 11-
310-110, 11-311-110 Front Tamper Move Failure RAP and 11-007-110, 11-008-110, 11-
312-110, 11-313-110, 11-319-110 Rear Tamper Move Failure RAP.
• Check that the output device is not near an air conditioning or ventilation output duct. Air
flow across the output bins can cause poor stacking.
