[ Case in the field ]
Description
In the field, the symptom occurred because the washer was returned to its original position after the new type compression spring was attached to the rear
side of the registration roller.
Field Remedy
The new service part compression spring has been offered to the rear side of the registration roller. With regard to the new service part, no washer is required
when attaching and color is also changed to gold. Therefore, pay attention to these points at time of replacement of the rear compression spring.
Note: No modification was made to the compression spring that is attached to the front side of the registration roller.
Type of service part compression spring and necessity of washer
Rear side: New type GOLD spring (FU6-2020) does not need the washer.
Rear side: Old type SILVER spring (FU6-2014) needs the washer (XD1-1106-219).
Front side: Existing spring (FU5-2611) needs the washer (XD1-1106-219).

[ Inspected by Canon Inc. ]
Description
Upon installation or when the drum unit is replaced with a new one, the following service mode item has to be executed to prevent white dots (sandy image)
from occurring: [Service mode > COPIER > FUNCTION > DPC > D-GAMMA]. Although rare in the case of a text image, however, the symptom may
appear in a limited degree when a fully black solid image is copied right after the execution of the item. This is because there is a lot of resistance in the
primary charging roller of the newly installed drum unit. In order to correct this symptom, follow the procedure below.
Field Remedy
Make the following selections in sequence: [Service mode > COPIER > TEST > PG], and then
1. In [TYPE], enter "12" (Halftone H60).
2. In [PG-PICK], enter the number of the cassette on which A3 size paper is loaded.
For example, If A3 paper is set on the cassette 1, enter "1" in this service mode item.
3. In [PG-QTY], enter "50" and press the Start key. (50 sheets of test print will be output.)
