Genicom 3600 User Manual

The following information identifies some possible printer problems and what
might be their cause.

• 

Problems with printer-to-computer communications, motor control, or
media advance may be caused by a faulty main PCB assembly.

• 

If information downloaded to the printer memory is lost after the printer is
powered off (lost data includes configuration setting changes reverting to
their factory defaults when power is cycled), the lithium battery may be
bad.

• 

The appearance of long white streaks in printed labels indicates a dirty
printhead or possible printhead failure.

• 

If you have problems with the bezel LEDs or the Feed/Pause button, you
may need to replace the bezel PCB assembly.

• 

If the printer no longer registers the use of marked label stock, you may
need to replace the label mark sensor.

• 

Light print on one side of a label can occur if the printhead is not making
even contact with the media. This condition can happen with any size
media, but is most common when using narrow labels where there is no
media between the printhead and the platen roller. Uneven lateral print
darkness may be eliminated by adjusting the bias screw.

• 

If the printer is no longer sensing when labels have been removed, you may
need to adjust or replace the label taken sensor.

• 

If the TTR takeup hub fails to roll up ribbon, you may need to replace the
upper drive belt and/or the TTR takeup clutch.

• 

If a ribbon fault occurs when the printer is in the TTR mode, you may need
to replace the TTR encoder sensor.

• 

If the liner takeup hub discontinues rolling up liner, you may need to
replace the liner takeup (lower) drive belt or clutch.

• 

If the platen roller does not turn but the liner drive roller does, you may
need to replace the platen roller gear.

• 

If none of the rollers turn, you may need to replace the stepper motor.
