Checking the print head

The printers of the 64-xx series are provided with a test function, which
tests the functio-nality of every single dot (dot check).
There are two different modes of operation with three different possibilities
to start a dot check:
Dot check modes
Automatic dot check
Dot check on demand
Tab. 2 The five ways to start a dot check.
Die Displayanzeige für einen defekten Dot ist bei allen Dottestvarianten:
Status: 5103
Dot defective
If all dots are faultless, no display message appears.
All five ways of dot checking test the entire printhead width. Therefore, the
test procedure may take from 10 s up to several minutes time (the wider the
printhead is and the more dots are defective, the longer).
