Cleaning the Platen and Exit Rollers
Clean the platen and rollers about once a month to remove excess ink. Use
the platen cleaner recommended by your supplier and proceed as follows:
1. Apply a small amount of platen cleaner to a soft cloth. Avoid
spilling platen cleaner inside the printer.
CAUTION
Do not use alcohol to clean the platen. Alcohol may cause the
rubber to harden.
2. Place the cloth against the platen and manually rotate the platen
knob.
3. To dry the platen, place a dry cloth against the platen and manually
rotate the platen knob.
4. Gently wipe the rollers using the cloth moistened with the platen
cleaner. Dry the rollers using a dry cloth.
There are two ways of replacing the ribbon. You can install a new ribbon
cartridge in the printer or refill the old ribbon cartridge with new ribbon from
a ribbon subcassette. Appendix A lists order numbers for ribbon cartridges
and ribbon subcassettes. The following procedure is for ribbon cartridges.
For ribbon subcassettes, refer to the instructions shipped with the
subcassette.
To replace the ribbon cartridge:
1. Turn off the printer.
2. Open the front cover of the printer. For easy installation, slide the
print head carriage to a position where it does not face a roller.
CAUTION
The print head may be hot if you have been printing recently.
