Section 8: Adjustment Procedures
RIBBON GUIDE PLATE ADJUSTMENT
Ribbon wrinkling has a negative impact on print quality and should be avoided. If ribbon wrinkling
is observed across the ribbon guide plate, adjustment may be necessary. Before adjusting the
ribbon guide plate, it is recommended that the print head balance be adjusted first, followed by
the guide plate if necessary.
The left side of the ribbon guide plate remains fixed and the right side is adjusted vertically. To
adjust the ribbon guide plate, follow the instructions below.
1 Load printer with media and ribbon as applicable.
NOTE: Figures 10-2 and 10-3 of the Diagrams & Schematics section
provides guidance on media and ribbon installation.
2 Connect the power supply cord, restore power, and test cycle.
3 Manually manipulate print head latch (1, Figure 8-4) to open print head (2).
NOTE: The printer will go into a standby mode when the print head is
opened. It is not necessary to turn the printer off.
4 Loosen set screw (3) to allow the right side of ribbon guide plate (4) to be adjusted.
5 Manipulate guide plate (4) until the ribbon seems to smooth itself out.
6 Retighten screw (3) to hold that position.
