17.12 Printing Troubles
Intermec EasyCoder 601 XP – Service Manual Ed. 2
The best way to start is to get an overall check of the printing, which
is easily done by ordering a series of test labels to be printed in the
in the Test Mode.
In case the printhead is suspected to be defect, it could be checked
by the following Intermec Fingerprint instructions (see Intermec
Fingerprint 7.12 Reference Manual):
• FUNCTEST$ ("HEAD")
• HEAD
• SYSVAR(21)
• SYSVAR(22)
Description:

No printout at all.

Possible Causes and Suggested Remedies:
• No hardware lock electronic key fitted in P34 on the CPU board.
- See chapter 17.4.
• Bad connection.
- Are both cables between printhead and CPU board fitted
correctly and not broken or otherwise damaged? The blue flat
cable from the inner connector on the printhead should run to
P41 on the CPU board and the thicker cable from the
printhead's outer connector to X2 on the power supply.
• 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 turned towards
the paper.
• Wrong printhead voltage.
- Check that the printhead voltage, P24, is +24V ± 1V (see
chapter 16.5).
• Wrong printhead pressure.
- Check that the printhead is completely lowered and pressing
against the paper web with a sufficient force, see chapter 8.9.
• Headlift sensor out of order.
- Check the headlift sensor as described in chapter 17.11.
