Maintaining the Printer

6.1 General Maintenance

The printer does not need preventive maintenance.
The casing of the printer and the platen will need cleaning from time to time.
Digital's computer-accessories catalog, DECdirect, lists suitable cleaners for
these tasks.
Always use the cleaners in accordance with the instructions on the cleaners..
Paper
Select the correct kind of paper for the job. Always make sure to position
paper squarely and set it tightly around the platen. Also make sure that
the printhead adjustment lever is in the correct position (See Section 3.3 in
Chapter 3). See Section 7.5 in Chapter 7 for paper specifications. To remove
paper from the printer, use the FF switch.
Ribbon Cartridge and Printhead
Keep samples of early printouts to help you know when to replace the ribbon
cartridge and printhead. Use only Digital-approved ribbon cartridges in the
printer. (Other cartridges may not give the same performance and may shorten
the life of the printhead.) See Section 6.3 in this chapter for information on
how to replace the ribbon cartridge, See Section 6.2 for tips on recognizing
when to replace the ribbon cartridge and printhead, or when to contact your
service representative.
