Printer Fault Messages
Description
Consistently low sensor
readings were detected.
Consistently high sensor
readings were detected.
The ribbon sensor values
have changed, or the printer
detects no or only sporadic
ribbon supply hub
movement.
The printer has shutdown to
allow the printhead
temperature to cool.
(continued)
Possible Solution(s)
Press any key to continue. Ensure that the reflective mark
was inserted facedown in the media sensor during the
appropriate calibration step; also, ensure that the reflective
mark is made of carbon based ink, and that the sensor is
free of debris. Retry calibration. If the problem persists, try
an 'Advanced Entry Calibration'; see Section 5.4.3.
Press any key to continue. Ensure that media was removed
from the media sensor during the appropriate calibration
steps; also ensure that no labels are stuck in the media
sensor. Retry the calibration. If the problem persists, call
for service.
Try the following:
1) Ensure that ribbon is correctly loaded and that the
printhead assembly is latched.
2) Check the ribbon supply and ribbon take up hubs for
obstructions that may be stopping movement.
3) Ensure that the ribbon core fits snugly on the ribbon
supply hub.
4) Ensure that the media and paper combination is not
slipping (usually caused by an incorrect match).
Turn 'Off' the printer until cool to prevent permanent
damage due to an excessive printhead temperature.
