Chapter 15—Troubleshooting
15.13 Transfer Ribbon Troubles
Description:
The thermal transfer ribbon breaks.
Possible Causes and Suggested Remedies:
• Wrong brand of ribbon.
- Check if the transfer ribbon is of an approved brand. If not, recom-
mend the customer to use approved brands only.
• Bad ribbon load.
- Check that the ribbon is routed so it runs above upper guide (that is,
the one where the upper part of the LSS is fi tted).
• Wrong paper type setup.
- Check that the printer is set up correctly for the type of thermal
transfer ribbon in use, see the User’s Guide.
• Wrong printhead voltage.
- Check printhead voltage, see Chapter 13.4.
Description:
The thermal transfer ribbon wrinkles.
Possible Causes and Suggested Remedies:
• Media misalignment.
- Is the edge guide positioned so as to guide the media closely along the
printer’s center section?
- Is the media supply roll as far in on the post or hub as possible?
• Ribbon misalignment.
- Are both the ribbon supply roll and the ribbon rewind core pressed as
far in on their hubs as possible?
• Ribbon path obstructed.
- Check that nothing obstructs the path of the transfer ribbon.
• Wrong or uneven printhead pressure.
- Check that the pressure arm is center-aligned in the relation to the
width of the media, see Chapter 7.8.
- Check the printhead pressure, see Chapter 7.8. Decrease the pressure
somewhat and test for both wrinkles and printout contrast. You may
need to feed out 25-50 cm of ribbon (1-2 ft.) before you can see any
effect.
• Bad ribbon break shaft adjustment.
- Check the adjustment of the front ribbon break shaft, see Chapter
6.6. Do not change the adjustment before you have performed all
other checks mentioned above.
