Stretching/Shrinking - Canon iR C3200 Series Service Manual

16.3.2.11.3 Color of output image is different from that of original: when thick paper is used
[ Manual-related ]
Field Remedy
Auto gradation adjustment has two different modes: for plain paper and for thick paper. If color reproductivity
is not stabilized with thick paper, execute auto gradation adjustment by selecting 'thick paper' mode.
16.3.2.11.4 Image is normal at 10cm area from image lead edge; however, right and left images
become interchanged on rearward area: paper size is A3
[ Case in the field ]
Field Remedy
There is a case in the field that the problem was solved by clearing the reader controller PCB's RAM. Turn the
power OFF/ON, and if the symptom still recurs, clear the reader controller PCB's RAM.
Before clearing the RAM, print the service mode setting values in service mode [COPIER> Function> MISC-
P> P-PRINT] in order to enter them as necessary after clearing the RAM.
Clear of RCON RAM can be done in service mode [COPIER> Function> CLEAR> R-CON].
16.3.2.11.5 PS-C1: Running 'ColorCAL' degrades gradation quality
[ Verified by Canon Inc. ]
Field Remedy
The quality of gradation may be degraded by running 'ColorCAL', as compared with the previous.
This symptom has been corrected with the PS-C1 system Ver.1.1.1, so upgrade it to Ver.1.1.1 and later if this
happens. Then, run 'ColorCAL' again.

16.3.2.12 Stretching/Shrinking

16.3.2.12.1 Image at trailing edge on 2nd side of A3 is distorted
[ Inspected by Canon Inc. ]
Cause
Since the rotation speed of the fixing roller is faster relative to the secondary transfer external roller, it is possible the
image can be stretched depending on the condition.
Field Remedy
In service mode level 2 [COPIER> Option> BODY> FX-SPD], set it to "-1".
As adverse effects of changing the setting, voids of 20mm-30mm long, image rubbing or voids along the trailing edge
could worsen. At that time, install the Spur (FG6-9657) to the ITB locking shaft. For the installation procedure,
refer to Service Manual [Troubleshooting > Correcting Faulty Images > Image Fault Case Studies > The output has
color displacement. > Mounting the Spur (FG6-9657)].
