Re: Need some help on CLC3200 problem

Hello,

I've printed a new PG grid, taking care about directions. Accordly to the pictures you've shared, It's a displacement in sub scanning direction only.

I've now entered in the copier the values from the P-Print that differs from those displayed in the copier. (PVE-OFST +4, ADJ-REFE +9, MF-A4R 127, ....)

No notable progress .Color print is the same.

I've done a color copy to provide an example (see the two pictures below)

90% of the Paper feed direction registration issues are caused by the ITB BELT UNIT-

1- OLD stretched out ITB BELT (not visible to eye)/ removing and cleaning inside of belt not always successful
2- the interior unit has a BLACK RUBBER DRIVE ROLLER (not the foam primary rollers) that becomes slick, the belt interior slips over it causing paper reg issues> poor alignment of COLOR GRID LINES- USE A GREEN PAD TO CLEAN IT's SURFACE
NOTE: DO NOT REMOVE THIS ROLLER TO CLEAN IT ( SPRING LOADED)

3- OLD DRUMS CAN CAUSE SUB-SCAN ISSUES ALSO-
4-The Pattern Reader can be out of position__(see manual for removal,cleaning,inspections) or it's dirty interior sensors /
MOST IMPORTANT TO CHECK AFTER PRINTERS ARE MOVED FROM ONE LOCATION TO ANOTHER

5- If YELLOW DRUM is OLD,it will cause>start those SUB-SCAN ISSUES
The Y pattern is used as the reference. The machine identifies the degree of color displacement in sub scanning direction with reference to the timing at which other color patterns are checked after a check on the Y pattern.
Printer doesn't always do the proper correction
