Description
Solution
REFLECTIVE MODE
FAULTY SENSOR
Consistently high
sensor readings
have been recorded.
Press any key to continue. Retry the STANDARD
CALIBRATION, ensuring that media is removed during
the appropriate step in the procedure (see Section
2.1.2).
If the problem persists, it can be due to one of
following reasons:
1) Possible debris in the Media Sensor; clean it then
retry calibration (see Section 2.4.3).
2) The Media Sensor may be defective; replace it (see
Section 4.7).
3) Possible defective Main Logic PCB; replace it (see
Section 4.11).
RIBBON FAULT
No rotation,
sporadic movement,
or unusable sensor
values have been
detected for the
Ribbon Supply.
Ensure that ribbon is correctly installed, that the
Printhead is latched, that the Leveling Cam is
adjusted, and that the printer is calibrated (see the
Operator’s Manual).
If the problem persists, it can be due to one of
following reasons:
1) The Ribbon Supply Hub may be bound; identify
then clear the obstruction.
2) The ribbon core may be loose on the Ribbon
Supply Hub; install a ribbon with a core that is
within specification.
3) The ribbon may be slipping over the media.
Possible causes include an incorrect media / ribbon
combination, a worn Platen, or a severely
misaligned printhead assembly; proceed
accordingly.
4) Possible damaged timing disk; replace the Ribbon
Supply Hub (see Section 4.5.1).
5) Possible occluded light pipe; clean it (see Section
4.5 for location).
6) Possible defective Backplane PCB; replace it (see
Section 4.12).
7) Possible defective Main Logic PCB; replace it (see
Section 4.11).
