Malfunctions,
cont'd.
• Wrong start and stop adjust setup.
- Check that the values for the start and stop adjust setup are
correct so the label is left hanging out over the dispensing
edge. Recommended values are start adjust -120, stop adjust
-33 .
• Defective sensor.
- If still no reaction, the sensor is probably defective and should
be replaced.
The best way to start is to get an overall check of the printing, which
is easily done by printing test labels, see chapter 13.1.
In case the printhead is suspected to be defect, it could be checked
by the following instructions (see Intermec EasyCoder 301 Direct
Protocol – Programmer's Guide):
• FUNCTEST$ ("HEAD")
• HEAD
• SYSVAR(21)
• SYSVAR(22)
Description:
No printout at all.
Possible Causes and Suggested Remedies:
• Bad connection.
- Is the cable between printhead and J9 on the CPU board fitted
correctly and not broken or otherwise damaged?
• Dirty printhead.
- Is the printhead clean? Residue from label adhesive or burnt
transfer ribbon on the printhead prevents it from functioning
correctly. Clean as described in the Installation & Operation
manual.
• Wrong type of receiving media.
- In case of direct thermal printing, verify that the stock of paper
is intended for direct thermal printing (not thermal transfer!)
and of approved quality.
• Wrong type of transfer ribbon.
- In case of thermal transfer printing, check that the ribbon is of
approved quality and fitted so it can move freely.
• Transfer ribbon incorrectly fitted.
- The “ink”-coated side of the ribbon must be facing the paper.
• Wrong printhead voltage.
- Check that the printhead voltage, 24V_PH, is correct (see
chapter 11.9).
• Wrong printhead pressure.
- Check that the printhead is completely lowered and pressing
against the paper web with a sufficient force, see chapter 7.7.
• Headlift sensor out of order.
- Check the headlift sensor as described in chapter 13.10.
