7.1.2. Printhead Cleaning
F
This maintenance operation should be done after each ribbon
exchange or not later than the print quality is reduced (unwanted
"lines" or "gaps" in the printout).
Please pay attention to the following:
- For the printhead cleaning there is no need to disassemble or
remove the printhead.
- The printhead can be damaged by electrostatic charges.
Therefore first of all touch a properly grounded part of the
printer (f.e. the base plate of the printer).
- If the printhead is axially adjusted please mark the actual
position before you start the cleaning work.
1.
Unscrew the two thumb screws on the printhead mounting until
the entire printhead mounting can be removed from the contact
shaft.
