MAINTENANCE AND LUBRICATION
1. Maintenance
In order to maintain the optimum performance of this printer and to prevent trouble, maintenance must be carried out
according to the following items.
1-1. Cleaning
(1) Removal of dirt
Wipe off dirt with a soft cloth soaked in alcohol or benzine.
*Note: Do not use thinner, trichlene or ketone solvents because they may damage plastic parts. Also during
cleaning, be careful not to moisten or damage electronic parts, wiring, or mechanical parts.
(2) Removal of dust, pile, etc.
Vacuum cleaning (with an electric cleaner) is preferred. Remove all dust, etc., inside the printer.
*Note: After cleaning, check the oil level. If it is not adequate due to cleaning, replenish it.
1-2. Checks
Checks must be carried out at two levels: “daily check” which the operator can easily carry out during operation, and
“periodic check” which an expert should carry out.
(1) Daily check
When the printer is used on a daily basis, check to be sure that the printer is being used properly. Make sure that
the printer is operating under the best conditions.
• Is any paper stuck in the paper box or printer case?
• Is the cartridge ribbon set to the right position?
• Is there any foreign matter inside the printer? (Remove.)
• Is the print head getting excessively dirty?
(2) Periodic check
After 6 months or printing 1,000,000 lines, the periodic check and lubrication must be carried out.
• Check for deformation of springs.
• Check the gap between the platen and the print head.
• Remove dust, dirt, etc., from near each detector.
