Service manual

RECOMMENDED SERVICE
To maximize service life (before maintenance is required), the total service life, and eliminate
potential problems that are harder to detect or test for, it is recommended the the service technical
perform the following procedures:
Clean the printhead (See Cleaning and Maintenance)
Removes loose contaminate build-up to prep the printhead for conditioning.
Condition the printhead (See Cleaning and Maintenance)
Use the Save-a-Printhead cleaning film to remove printhead contamination buildup. (Part
No.105950-047)
Verify the DC voltage setting (see the DC Power Verification & Adjustment procedure,
980428-105) If the DC voltage setting is too low, the motor torque may be too low to print or
dispense (peel) labels in the worst case print conditions. If the voltage is set too high the
electronic components may be damaged.
Verify the label rewind tube’s torque setting (see the Tube Tension Verification and
Adjustment procedure, 980428-154). The rewind tube’s clutch torque level slowly degrades
with use. Labels may not dispense properly if this setting is too low to pull the backing off the
labels.
Print a Printer Status / Dump Mode Label with the AutoSense routine (see user’s
manual) and once with the Printer Information utility (see procedure 980428-157). This
verifies that the printer can print ( take special note to the slanted lines as a basic printhead
test), sense labels, and communicate with software.
