6. Cleaning and Maintenance
Once a week or if message "15" is
displayed, the print head must be
cleaned manually.
Preparing the printer
• Open the printer lid and then
press buttons CLEAN and
LOADED simultaneously.
• The print head (72) moves
upward to a position approx.
1 cm away from the sealing lip
( Fig. 53 ).
6.2 Clean print head
• Carefully insert the swab (89) into the gap
under the print head and apply light pres-
sure upwards (on print head) and move the
foam swab back and forth ( Fig. 55 ) (approx.
10 times!).
This procedure removes dried ink residues.

• Push the lever (69) upwards, then remove
the red location plate (70) with the sealing lip
( Fig. 54 ).
• Moisten one of the foam swabs supplied with
the instrument (73) with some alcohol. Be sure
not to use too much alcohol—no alcohol may
drip into the instrument.

Never use acetone or xylene! Only use
alcohol 95 % or 100 % for cleaning pur-
poses.
Never rotate the swab—this can dam-
age the nozzle plate of the print head.
