Symptom
When making a copy of solid color image, a ghost image may occur.
Cause
When making a copy of solid color image, wax included in toner may be exuded and attached onto the fixing assembly.
As a result, a part of the image may be attached onto the fixing roller, possibly resulting in the ghost image.
This symptom tends to occur more frequently when the fixing assembly is replaced to new one.
Remedy in the Field
This service mode can be executed in user administrator mode as well. (For detail, see the user mode list shown in the product specifications of the introduction
edition)
Go through the following procedure:
1. Execute aging (print a image: 50 copies/total) using the following image.
- 10 sheets of A3 (2-sided) solid color (Green) image in full color mode
- 10 sheets of A3 (2-sided) solid color (Blue) image in full color mode
- 10 sheets of A3 (2-sided) solid color (Red) image in full color mode
- 10 sheets of A3 (2-sided) solid color (Black) image in monochrome mode
- 10 sheets of A3 (2-sided) solid color (white) image in monochrome mode
2. Execute the service mode (refresh of the fixing roller).
COPIER > OPTION > CLEANING > FX-CLN-E (Level12)
3. If the remedy above is ineffective, decrease the control temperature by the following service mode (fixing control temperature adjustment).
In COPIER > OPTION > BODY > TEMP-TBL, select "3" as a setting value and execute. (When selecting "3", control temperature decreases by 15 deg C)
By executing this service mode (fixing control temperature adjustment), there will be an improvement in this symptom, however, gloss will decrease.
