Can not communicate through the
parallel port:
Observe the Ready Indicator as the format is sent to the printer. If it does not
flash, check the parallel cable type. Also, check the protocol and port settings
between the printer and host.
Can not load media through the
optional cutter:
WARNING! Use extreme care. Turn ‘Off’ and unplug the printer before proceeding.
Ensure that the cutter is properly installed. Plug in and turn ‘On’ the printer. You
should hear the cutter blade rotate and position itself properly. However, if the
problem continues call for service.
* The LCD is blank, but the
Ready Indicator is ‘On’:
The display contrast may set too low. Press and hold the MENU Key for 10
seconds or until the display reappears.
Erratic feeding:
The printer may require Calibration;
Printers without front display: Perform calibration, see section 4.7.1.
Printers with front display: Press and hold the
FEED
button until at least
one label gap or mark is advanced.
Erratic printing (instead of the
label format, strange characters
are printed):
The printer may be in Hex Dump Mode; see Section 7.2.
If using the serial port for communicating, check both the host and printer port
settings; the printer may be set to eight data bits while the host is set to 7 (or
vice versa).
