10 Maintenance
Your printer requires very little care. Occasional cleaning and replacement of the ribbon
cartridge are all that is required. Cleaning is recommended approximately every 6
months or 300 hours of operation, whichever is sooner. Lubrication of the printer is not
usually necessary. If the print head carriage does not move smoothly back and forth,
clean the printer in the manner described in this chapter. If the problem continues,
contact your dealer.

10.1 Cleaning
The housing and the top cover of the printer help protect it against dust, dirt, and other
contaminants. However, paper produces small particles that accumulate inside the
printer. This section explains how to clean and vacuum the printer and how to clean the
paper bail rollers. It is easier to clean the printer when the cover is open.
10.1.1 Cleaning and Vacuuming the Printer
If the print head carriage does not move smoothly back and forth or paper particles have
accumulated in the printer, clean the printer.
To clean and vacuum the printer:
1) Remove any paper from the printer. Make sure that the power is off, and then
disconnect the printer power cord.
2) Using a soft vacuum brush, vacuum the exterior of the printer. Also vacuum the cut
sheet edge.
3) Use a soft, damp cloth to wipe the exterior of the printer, including the cover. A mild
detergent may be used. Do not use solvents, kerosene, or abrasive cleaning
materials that may damage the printer.
4) Open the cover of the printer and remove the ribbon cartridge. Using a soft vacuum
brush, gently vacuum the platen, the print head carriage and shaft, and surrounding
areas. You can easily slide the print head to the left or right when the power is off. Be
careful not to press too hard on the flat head cable that extends from the print head
carriage.
5) Re-install the ribbon cartridge.
10.1.2 Cleaning the Paper Rollers
Clean the platen and paper bail rollers occasionally or when stains or smudges appear
on the paper. Use a mild detergent as appropriate. Do not use alcohol to clean the
platen or the rollers. Alcohol may cause the rubber to harden.
To clean the rollers and the platen:
1) Apply a small amount of water to a soft cloth. Avoid spilling liquid inside the printer.
2) Place the cloth against the platen and manually rotate the hand wheel.
3) Repeat this procedure for each roller.
4) To dry the platen, place a dry cloth against the platen and the rollers and manually
rotate the paper feed knob.
