Paper-advance calibration
The purpose of this Service Calibration is to calibrate the nominal advance of the paper to compensate
for any irregularities in the drive roller, which is not a perfect cylinder. Calibration is necessary to
control the precise movement of the paper in order to avoid print-quality problems such as banding.
1. In the Service Calibrations submenu, select Paper Advance Calibration and press OK.
2. The Paper Advance Calibration submenu offers four options.
●
Check calibration status tests whether the current calibration values are valid.
●
Perform new calibration performs a calibration in order to obtain a new set of
calibration values. The calibration values are automatically set to zero when a calibration
process is launched.
●
Reset current calibration sets all the calibration values to zero.
●
Show current calibration values displays the current calibration values.
Check calibration status
This option tests whether the current calibration values are valid. The process is very similar to the
calibration process. The printer makes a series of paper advances, and the OMAS sensor registers the
distance covered in each advance.
