The correct cleaning of the print heads is decisive for the printing quality
and the availability of the printer!
If a print head is not cleaned often enough or not at all, then the ink film and
drops adhering underneath would harden with time and clog the nozzle
plate. Since once nozzles are clogged, only rarely can they be cleaned
again, either you’ll have to accept longitudinal, white stripes in the prints
from now on or else buy a new print head for thousands of Euros and install
it.
But print heads can also be destroyed by incorrect cleaning methods,
namely, whenever too much pressure is exerted against the nozzle plate
when cleaning manually, but also, in particular, when the wrong type of
cleaning cloths are used: either ones that are already dirty or ones that
have a fuzzy surface and leave behind fibers on the nozzle plates with each
wipe, clogging the nozzles.
Please emphasize to your employees how important it is to always handle
the print heads with care and to strictly observe the cleaning procedures
and intervals!
Notice
If the print heads are not cleaned often enough or are cleaned incor-
rectly, this will result in the loss of all warranty rights!
10.7.5.1 Mechanical cleaning of the nozzles
The print heads are cleaned with the aid of the cleaning program in the
touchscreen. Ink is used to clean the print heads.
The cleaning process can be carried out on a single print head or on sever-
al print heads simultaneously.
A standard or intensive cleaning program can be selected.
