Status Indicator RAPs
11H-120 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.
Procedure
WARNING
Ensure that the electricity to the machine is switched off while performing tasks that do
not need electricity. Refer to
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 the IQ1 Image Quality Entry
RAP.
For other copy / print damage and dog ears, go to the 11G-120 Copy Damage in the 1K LCSS
RAP.
Check the following:
• Check that bin 1 is seated correctly and the bin 1 alignment clip is in position, PL 11.100
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 11.104 Item 11 , the flag, PL 11.104 Item 7 and the paddle motor
assembly, PL 11.104 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).
• Make sure the paddles are clean. If necessary, use formula A cleaning fluid, PL 26.10
Item 2 to clean the paddles.
• 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 11.112 .
• 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 11.120 .
• Inspect the four spring loaded guides on the output cover, PL 11.100 Item 7 . Ensure that
they are correctly located and are free to move up and down.
11J-120 1K LCSS Poor Stacking RAP
Use this RAP to find the cause of poor stacking in the 1K LCSS.
Procedure
WARNING
Ensure that the electricity to the machine is switched off while performing tasks that do
not need electricity. Refer to
GP 14 . Disconnect the power cord. Electricity can cause
death or injury. Moving parts can cause injury.
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
11.100 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 11.1-120 1K LCSS Bin 1
Level.
• Check that the bin 1 upper level sensor, Q11-332 is working correctly. Refer to the 11-030-
120, 11-334-120, 11-335-120, 11-336-120 Bin 1 Movement Failure RAP.
• Check the operation of the front and rear tampers. Refer to 11-005-120, 11-006-120, 11-
310-120, 11-311-120 Front Tamper Move Failure RAP and 11-007-120, 11-008-120, 11-
312-120, 11-313-120, 11-319-120 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.
• Check if Mod. TAG L-013 LCSS bin 1 kit is installed on the finisher.
– Machine that regularly process large stacks of A4/8.5x11 inch LEF paper should
have the LCSS bin 1 W/
TAG L-013 kit installed, PL 11.100 Item 10 .
– Machines that regular process small stacks of A4/8.5x11 inch LEF, A3/11x17 inch
and A4/8.5x11 inch SEF paper should have the standard W/O
TAG L-013 bin 1
installed, PL 11.100 Item 10 .
• Check the output copies for curl, refer to IQ5 .
