Explanation
The image contrast may vary, depending on the date and time when copying or printing is performed or the type
of copy/print job. To constantly maintain image quality, shorten the waiting period until image quality control is
performed.
Procedures
* The service technician must perform the adjustment in accordance with the procedures below.
(1) Enter setting mode [08]. Change the value for code [2505], [2507], [2508], [2509], [2677] or [9190] to
specify the best interval during which image quality control should be performed, according to use of the
MFP.
The MFP is installed in a place where the temperature and humidity vary widely:
Set "1" (value × 5%R.H.) for code 08-2505 to increase the frequency of image quality control, in response to
a change in humidity.
* Image quality control will be performed, when the relative humidity changes in accordance with the
specified difference from the previous image quality control. If the difference in the relative humidity
exceeds the specified value, image quality control is performed first. Then a copy or print job will be
performed.
