Adjustment of Image Registration
First, all Image Position Adjustments are referenced to Magenta. So, first make certain that Magenta
Image Quality is at its best in this regard. Next, the levelness of the floor can negatively affect the Image
Positon. If the engine is moved even a few inches it can affect Image Registration. The Image
Registration and Position Adjustments are executed based on the premises that the Media or Paper is cut
to the appropriate size and is square. It is also based on the foundation that the four (4) corners of the
paper are at a right angle.
The subsequent Medias are recommended for the Image Registration Adjustment: 1
•GF-C081 81.4 g/m2
•OK Top Coated + 128 g/m2
•Hammermill Color Copy Digital 28lb 105 g/m2
•CANON-OCE TOP COLOR 100 g/m2
It is also acceptable to use Media which an End User utilizes frequently to perform the Image Position
Adjustment.
When performing the Image Registration Adjustments Canon U.S.A., Inc. strongly recommends
performing the subsequent Procedures:
•Standard Value Of Left Edge Margin (Mechanical Adjustment for Cassette, Execute with all paper
sources)
•Standard Value of Leading Edge Skew
•Standard Value of Leading Edge Right angle (based on an assumption that right angle accuracy of paper is
correct)
•Standard Value of Trapezoid
•Magnification Ratio in Horizontal Scanning Direction
•Magnification Ratio in Vertical Scanning Direction
•Standard Value of Left Edge Margin/Leading Edge Margin (1st side/2nd side: Software Adjustment)
1For the detailed procedure for the Image Registration Adjustment, please reference the Adjustment for Image Registration
in the Appendix, or in the imagePRESS C800 Series Service Manual, 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.

Image Position Adjustment
The Image Position Adjustment 2is 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/m2
•OK Top Coated + 128 g/m2
•Hammermill Color Copy Digital 28lb 105 g/m2
•CANON-OCE TOP COLOR 100 g/m2
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
2For 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.

Use Care Removing /Mounting the Induction Heating Unit
When the Induction Heating (IH) Unit is inserted into the Fixing Belt Unit, E007 Errors can result if care is not
used. First, fit the Hook [3] into the Front Side []of the IH Unit to the Groove [A] on the Front Side of the
Fixing Belt Unit, and then fit the Hook [4] into the Rear Side []to the Groove [B] on the Rear Side. As it is
hard to see the Hook fit into the Groove, be careful not to let the Hook of the IH Unit come in contact with
the Fixing Belt.

Use Care Mounting the Fixing Belt Displacement Control Motor Unit
If the Fixing Belt Displacement Control Motor Unit [A] is not mounted properly, some likely issues that could
occur are E007-0001, 0011, 0021.
Mount the Fixing Belt Displacement Control Motor Unit by connection of the Posts [A] and [B] to the Hole
[C] and the Hook [D] of the Fixing Belt Displacement Control Motor Unit.
[B]

NOTE:
When mounting the Fixing Belt Displacement Control Motor Unit, use care not to touch the
Fixing Belt. When positioning the Hook [D], and the Post [B], move the Tension Arm [3]to
make it easier.

Fit the Post [B] of the Fixing Belt Unit into the Plastic U-Shaped Hole [D] of the Hook. The Post [E] on
the Fixing Belt Unit should insert into the Hole [F].
3) Place the Fixing Belt Displacement Control Motor Unit over the Boss on the Fixing Belt Unit and secure
them with a New Screw. Be sure that the Metal Plate [A] of the Fixing Belt Unit does not rest on top of the
Boss [B] on the Fixing Belt Displacement Control Motor Unit.
When attaching the Fixing Belt Displacement Control Motor Unit to the Fixing Belt Unit,
always use a New Screw. The Screw used to attach the Fixing Belt Displacement Control Motor
Unit should not be reused once it is removed!

Use Care Mounting the Pressure Belt Displacement Control Motor Unit
If the Pressure Belt Displacement Control Motor Unit [A] is not mounted properly, some prospective issues
that could develop are E007-0012, 0022, and 0102.
1) Mount the Pressure Belt Displacement Control Motor Unit by fitting the Posts [1], [2] and the
Positioning Boss [3] on the Pressure Belt Unit to the Hook [4], the Hole [5], and the Positioning
Cutout [6] on the Pressure Belt Displacement Control Motor Unit. When positioning the Hook [4] and
the Post [1], move the Tension Arm [7] to make it easier.

2) After positioning the Pressure Belt Displacement Control Motor Unit, fasten it with a New Screw.
Clearing the Fixing Belt Unit Counter
If the Fixing Belt Unit Counter is not cleared after component replacement, or if the Fixing Belt Unit is not
mounted properly, some potential issues that could arise are E007-0001, 0011 and 0021.
After replacement of the Fixing Belt Unit, performance of the Operation Check from Service Mode can
suppress failures due to inadequate mounting, etc. Navigate to Service Mode: FUNCTION > FIXING > FIX-
UHP and execute the operation check.

NOTE:
•Use care not to damage the Fixing Belt during mounting.
•After replacement of the Fixing Belt Unit, apply Grease (SE1107; FY9-6036-000)
respectively to the four (4) Gears [1] on the Pressure Belt Unit and the Gear [2] of the
Fixing Drive Assembly.
Amount of Grease to apply: about in an amount of five (5) grains of rice per Gear
(approximately 100 mg).
When attaching the Pressure Belt Displacement Control Motor Unit to the Pressure Belt Unit,
always use a New Screw. The Screw used to attach the Pressure Belt Displacement Control
Motor Unit should not be reused once it is removed!
IMPORTANT!

If the Grease on the moving Gears [1] of the Fixing Belt Unit is depleted, apply the Grease (SE1107) onto
entire circumference of the Gear [A] surfaces as needed.
After replacement of the Fixing Belt Unit, be sure to execute Counter Clear for the unit. Navigate to Service
Mode: FUNCTION> DRBL-1 >FX-BLY-U " to execute the Counter Clear. If a Count Clear is not executed,
the data history before replacement of the unit is resumed. This can eventually result in E007-0001, 0011 and
0021 Errors.
Use Care When Mounting the Pressure Belt Unit
If the Pressure Belt Unit is not mounted properly, the issues which could develop are Faulty Images and E004-
0101 Errors which result due to the breakage of the Halogen Heater.
1) Before mounting the Pressure Belt Unit, check if the Bearings at both ends of the Pressure Roller do not run
on the Support Plate. If they do, correct their positions.
