Fujitsu DL3800 manual Replacing the Ribbon, Rubber to harden

		MAINTENANCE
	Cleaning the Platen and Paper Bail Rollers
	Clean the platen and paper bail 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 paper bail rollers using the cloth moistened
		with the platen cleaner. Dry the rollers using a dry cloth.
REPLACING THE RIBBON	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
		bail roller.

CAUTION

The print head may be hot if you have been printing recently.
