Troubleshooting The whitest vertical line should be positioned in the 0 offset column with minor variations between +2 and -2 columns. If the offset is not positioned on the 0 column or between +2 and -2 columns and the whitest vertical varies greatly, the printer requires Paper Advance Calibration (Main Menu/Image Quality Maintenance/Paper Advance Calibration/Calibrate Paper Advance). NOTE: It is very important to check that the loaded paper is the same paper type as selected in the front panel. You can check the paper type selected through the Front Panel (Main Menu/Paper menu/ View loaded paper). The wrong type of paper selected will produce an offset error in the Paper Advance.

The following plot shows a bad paper advance, there is a straight white line positioned close to the -6 column, instead of the 0 column for the majority of the points. 14 Chapter 1 Troubleshooting ENWW
