4.7 Avoiding wrinkling of the ribbon
If the ribbon wrinkles, the ribbon tension on either side of the ribbon will not be even. Remove slack
on the ribbon in the following order:
Removing slack on winding side of ribbon (in front of printhead)
1. Open the top cover all the way until it stops at hinges and unlock the printhead assembly by
pushing the printhead release lever and open it towards the left side of the printer all the way
until it stops and stands upright.
2. Loosen ribbon guide plate thumbscrews on both ends of the ribbon guide plate. Do NOT remove
them just loosen them one turn. Never loosen screws other than these.
You should be able to make adjustments to the ribbon guide plate with the ribbon installed.
However, it may be easier to detach mandrels form the ribbon mandrel holders. This will depend
on the ribbon width being used.
3. Remove slack and wrinkles on both sides.
• When they are found on the right side of the ribbon (viewed from the front of the printer),
move the right end of the ribbon guide plate towards you,
• And when they are found on the left side of the ribbon (viewed from the front of the printer),
move the left end of the ribbon guide plate towards you the plate can turn on the center set
screw as the rigid point of support.
4. Check to see that slack and wrinkles on the ribbon are removed completely, and lastly tighten
the guide plate thumbscrews on both ends.
