Troubles (not

Intermec EasyCoder 301 – Service Manual Ed. 3
Description:
Transfer ribbon gets wrinkled.
Possible Causes and Suggested Remedies:
• Paper misalignment.
- Are all guides positioned so as to guide the paper web closely
along the printer's centre-line wall?
- Is the paper roll fitted as far in on the media hanger as possible
and the guide properly adjusted?
• Ribbon path obstructed.
- Check that nothing obstructs the path of the transfer ribbon,
e.g. cables to the printhead.
• Wrong or uneven printhead pressure.
- Check the printhead pressure, see chapter 7.7. Decrease the
pressure somewhat and test for both wrinkles and printout
contrast. You may need to feed 25–50 cm of ribbon (1-2 ft.)
before you can see any effect.
• Bad ribbon break shaft adjustment.
- Check the adjustment of the ribbon break shaft, see chapter
6.5. Do not change the adjustment before you have performed
all other checks mentioned above.
Description:
Transfer ribbon breaks.
Possible Causes and Suggested Remedies:
• Wrong brand of ribbon.
- Check if the transfer ribbon is an approved brand. If not,
recommend the customer to use approved brands only.
• Incorrect ribbon load.
- Check that the ribbon is loaded so it runs above the ribbon/
media sensor.
- Check if the ribbon is loaded so the spools rotate in the correct
direction. If the ribbon unwind spool is forced to rotate
clockwise (instead of counter-clockwise), it will get jammed.
This typically occurs when using ribbon wound with the
"ink"-coated side facing outward by mistake.
• Wrong paper type setup.
- Check that the printer is set up correctly for the type of thermal
transfer ribbon in use, see Installation & Operation manual.
• Wrong printhead voltage.
- Check printhead voltage 24V_PH on test point TP_PH, see
chapter 11.9.
