If they are not valid, the front panel displays the reason (for example, the AMP1 parameter value is greater
than the maximum allowed).

Perform new calibration
This option performs a calibration in order to obtain a new set of calibration values. The printer makes a
series of paper advances, and the OMAS sensor registers the distance covered in each advance. When all the
paper advances have been performed, the calibration values are calculated based on the data obtained.
NOTE: Before starting the process, make sure that HP Coated Paper is loaded and ready to print.
1. The printer checks that there is paper ready to print. If there is no paper ready, the following message is
displayed. After a few seconds, the front panel automatically returns to the Paper Advance Calibration
submenu.
2. If there is paper ready, the printer performs the zero search for the Paper Motor. During this phase, the
following message is displayed.
3. When the Paper Motor has been initialized, the printer starts to perform the series of paper advances.
During this process, the front panel displays the current iteration number and the total number of
iterations.
You can cancel the calibration process at any time by pressing Cancel. In this case, the previous
calibration values are restored and the cancelled process has no effect on the printer.
