Image Position Adjustment
The Image Position Adjustment

is very important and many factors are involved. As previously mentioned, all
Image Position Adjustments are referenced to Magenta. So again, first make certain that Magenta Image
Quality is at its best in this regard. Again, the levelness of the floor can negatively affect the Image Positon. If
the Engine has been moved, even a few inches, it can affect the Image Position. Furthermore, routine
procedures like removal and re-installing the Registration Assembly can negatively affect the Image Position.
The Image Position Adjustment should be performed if any of these situations are encountered.
The subsequent Medias are recommended for the Image Position Adjustment:
•
GF-C081 81.4 g/m 2
• OK Top 128 g/m 2
• Hammermill Color Copy Digital 28lb 105 g/m 2
•
CANON-OCE TOP COLOR 100 g/m 2
It is also acceptable to use Media which an End User utilizes frequently to perform the Image Position
Adjustment.
When performing the Image Position Adjustment, Canon U.S.A, Inc. strongly recommends performing
the subsequent Procedures:
• Adjusting the Image Position
•
Correct Image Misalignment
• Correct Distortion (Parallelogram)
• Correct Distortion (Trapezoid)
• Adjusting the Zoom Ratio of the Image
•
Adjusting Left Edge Alignment of the Image
• Adjusting Lead Edge Alignment of the Image
2 For the detailed procedure for the Image Position Adjustment, please reference the Adjustment for the Image Position in the
Appendix, or in the imagePRESS C800 Series Service Manual, Chapter 5 Adjustment > Basic Adjustment > Image
Position Adjustment > Checking/Adjusting or Chapter 9, Installation > Installing the Host Machine > Image Position
Adjustment > Checking/Adjusting.
IMPORTANT!
Do not use Recycled Paper, Textured Paper, or Vellum Paper. Variation in feed
performance is more likely to occur with these type Medias. Use of these type
media can result in a flawed Image Position Adjustment.
