17.13 Printing Troubles
The best way to start is to get an overall check of the printout quality by
printing a series of test labels in the Test Mode.
If you suspect a defective printhead, you can check it out using the fol-
lowing Intermec Fingerprint instructions (see Intermec Fingerprint v8.xx,
Programmer’s Reference Manual):
• FUNCTEST$ ("HEAD")
• HEAD
• SYSVAR(21)
• SYSVAR(22)
Description:
No printout at all.
Possible Causes and Suggested Remedies:
• Bad connection.
- Is the cable between the printhead and P5 on the driver board fi tted
correctly and not broken or otherwise damaged?
- Is the cable between the printhead and J40 on the CPU board fi tted
correctly and not broken or otherwise damaged?
• Dirty printhead.
- Is the printhead clean? Residue from label adhesive, thermal paper
topcoating, or preprint ink prevents the printhead from functioning
correctly. Clean the printhead as described in the User’s Guide.
• Wrong type of direct thermal media.
- In case of direct thermal printing, verify that the media is intended
for direct thermal printing (not thermal transfer!) and of an approved
quality.
• Wrong type of thermal transfer ribbon.
- In case of thermal transfer printing, verify that the stock of ribbon is
of an approved quality.
• Transfer ribbon loaded incorrectly.
- Verify if the ribbon is loaded with the ink-coated side facing the
receiving face material. If not, reload the ribbon as described in the
User’s Guide.
• Transfer ribbon mechanism failure.
- See Chapter 17.14
• Wrong printhead voltage.
- Check the printhead voltage +24 VDC ±2V (see Chapter 15.4). If the
power on the CPU board is OK, but the trouble remains, disconnect
the power cable on the inner side of the printhead and use probes to
measure the voltage during printing between two adjacent lines in the
socket. If wrong voltage, check driver board and cables.
