Replacing the cleaning unit

If the print quality is no longer good enough, you
should try cleaning the printhead (see sections
"6.1.1 Printhead cleaning" and "6.1.2 Printhead
flushing"). The cleaning unit has to be replaced if
the print quality has still not improved.
For this, we offer the following service set:
