[ Case in the field ]
Description
In the field, when a book or an original with creases was copied, the shadow caused by the gap between the book and the copyboard glass or the creases of
the original was recognized as fogging, and as a result, the contact image sensor was replaced with a new type one to improve the symptom. When the
symptom is pointed out, follow the procedure below.
Field Remedy
1. Take notes of the CIS label value (MTF-MG) affixed on the side of the new type contact image sensor unit (FL2-3000).
Note: Regarding the new type contact image sensor unit, its CIS label describes the parts number "FL2-3000-xxx", too.
2. Replace the contact image sensor unit with a new type one.
3. In service mode [COPIER > ADJUST >CCD > MTF-MG], input the CIS label value that was taken note of in Step1.
4. In service mode (Level 2) [COPIER > OPTION > BODY > CCD-TYPE], input "1".
5. Place more than 10 sheets of white paper (that has the highest level of whiteness among all types of paper the user uses) on the copyboard glass, and then
perform the CIS white level adjustment in service mode [COPIER > FUNCTION > CCD-ADJ].
6. When the DADF-M1 is used, place the paper the user often uses on the copyboard glass, and then perform the ADF white level adjustment in service mode
[COPIER > FUNCTION > CCD > DF-WLVL1/2].
7. Hold down the control panel switch for more than 3 sec. > press [Start] on the LCD > turn the main power switch OFF following the instruction on the
LCD > wait 10 sec. or more > turn the main power switch ON again.
