Chapter 11 Maintenance and Troubleshooting
This printer requires very little regular maintenance other than replacing ribbons. The print
head should last about seven hundred million draft characters and is easy to replace. Beyond
this, adjust the print wire flight time compensation from time to time to recover print quality lost
through print head or carriage mechanism wear.
Clean the Printer
Cleaning is recommended about once every 500 hours of operation. How often the printer is
cleaned depends on the environment and on the dust and lint content of the paper.
WARNING
Turn off the power switch and unplug the printer from the wall outlet before cleaning the printer.
If the printer has been printing, avoid touching the print head before it cools down.
•
Remove the top door by raising it approximately one quarter of the way and then lifting it
from the printer.
•
Open the print gap
•
Remove the ribbon cartridge.
