2.3 Ribbon Path Alignment

If irregular voids extend intermittently, diagonally through an image printed with ribbon, the cause
may be due to ribbon overlap (wrinkling). However, other factors can be involved. Begin
troubleshooting by verifying correct adjustment of the Leveling Cam (Section 2.2.1), Printhead
Pressure (Section 2.2.2), and Burn Line (Section 2.2.3). Also, examine the platen for wear, debris
buildup, and excessive lateral movement. If all of these adjustments and components are in good
order, then perform a Ribbon Path Alignment as follows:
