Can not communicate through
the parallel port:
Watch the display. The Comm Indicator (see Section 4.1) will flash as
data is received. If COMM does not appear, check the parallel cable
type; also, verify the protocol and port settings of the printer and host.
The graphic display is blank,
but the blue backlighting is
‘On’:
The display contrast may set too low. Turn the printer ‘Off’ and ‘On.’
Wait for ten seconds. (If the printer is equipped with at network card
wait for two minutes.) Press and hold the MENU Key. (It can take up
to 15 seconds to cycle through the contrast range, see Section 4.1 for
the menu key layout.)
Erratic feeding: The printer may require a Quick Media Calibration; see Section 5.1.1.
Erratic printing (instead of the
label format, strange
characters are printed):
• The printer may be in Hex Dump Mode; see Section 6.3.
• If using serial communications, check 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).
Light print on the right or left
side of the label:
• The Leveling Cam may be incorrectly adjusted; see Section 5.1.1.
• The Head Lift Lever may not be locked; see Section 3.4.
• The Platen Roller may be dirty or worn; see Section 5.4.2.
