Checking Image Margin - Canon imagePRESS 1135 Series Service Manual

Checking image margin

1) Select the pickup cassette specified where you set either A3 (297 mm x 420 mm) or
11 x 17 inch (279 mm x 432 mm) paper in the following Service Mode.
CAUTION : Checking paper size
For image position adjustment, the following paper sizes are used as reference:
A3 paper: 297 mm x 420 mm
11 x 17 inch paper: 279 mm x 432 mm
In the case that the trail edge margin and the right edge margin do not meet the
specification of 2.5 mm after executing adjustment, be sure to check the size of paper
you used because the paper dimension may differ from the official size.

NOTE:
Use the paper which users are normally using when executing the image position
adjustment. However, take note of the following points.
• Do not use embossed paper or vellum paper because they may cause variation in
adjustment from feeding performance viewpoint.
• Always use the same paper to execute adjustment because this image position
adjustment (by Service Mode) executes adjustment for all the paper registered in the
management setting for paper type.
(Image position adjustment is also available by selecting the following: [Additional
Functions] > [System Settings] > [Paper Type Management Settings]. However,
adjustment in [Additional Functions] is executed on each registered paper basis.)
If there are many variations in position adjustment with user's paper, use the following
paper or equivalent paper.
