17.12 Printing Trou-
bles
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 v7.61, Programmer’s Reference Manual
):
• FUNCTEST$ ("HEAD")
• HEAD
• SYSVAR(21)
• SYSVAR(22)
Description:
No printout at all.
Possible Causes and Suggested Remedies:
• Bad connection.
- Are both cables between printhead and CPU board fi tted cor-
rectly and not broken or otherwise damaged? The blue fl at
cable from the inner connector on the printhead should run to
P41 on the CPU board and the thicker cable from the print-
head’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 User’s Guide.
• Wrong type of receiving media.
- In case of direct thermal printing, verify that the stock of
media 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 fi tted so it can move freely.
• Transfer ribbon incorrectly fi tted.
- The “ink”-coated side of the ribbon must be turned towards
the receiving face material.
• 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 media with a suffi cient force, see Chapter 8.9.
• Headlift sensor out of order.
- Check the headlift sensor as described in Chapter 17.11.
