Maintenance
To keep the printer in peak working condition, extend its life for a long term and prevent
operational failures, follow the maintenance procedures below.
Cleaning
CAUTION:
•
Never clean the thermal head with solvents other than the specified ones, since
other solvents could damage the thermal head or cause the malfunction of
parts.
•
Since the head area and each motor surface can become hot right after
printing, allow about 15 minutes for them to cool.
Thermal Head Cleaning
The head heating elements of the printer module will collect dust after printing for a long period
of time because of heat sensitive materials contained in the paper, that could affect printing
quality. In this case, clean the thermal head using the steps below.
1. Turn off the power.
2. Open the cut sheet presenter module. (See "Opening/Closing Units and Modules" on page
3-4.)
3. Open the platen unit using the lever, platen, and remove the paper.
4. Wipe off the dust on the head heating elements using a cotton swab dampened with alcohol
solvent, such as ethanol, or IPA.
