9.1 General maintenance
If the printer will not be used for a prolonged period,
turn off the printer. Then disconnect the USB cable,
the Ethernet cable, and the power cord.
Please observe the following:
The print-head nozzles can become dried up or
clogged. You should periodically use the printer in
order to avoid such damage. The printer should be
turned on once a week for a few minutes.
If you do not use the printer for a long time, always
check first to see if the nozzles are clear.
Print out the nozzle-test pattern (→ Print nozzle
test), from the internal maintenance menu on the
printer (→ "Service" menu). If necessary clean the
print heads (→ Clean print heads) and then start the
printing.
If you do not use the printer for a long time, imper-
fections may then develop in the printing even if mul-
tiple print head cleanings are carried out. If this hap-
pens, shut down the printer for 30 minutes. Then
turn on the printer again and run through a nozzle
test and a print head cleaning.
NOTE
Dried-up ink will work free after the print
heads have been cleaned multiple
times. Normal printing should then be
possible.
If even these multiple cleaning fails to
help, contact The Weidmüller service or
a sales representative.
9.2 Maintenance via the display
The "Maintenance" menu allows you to change
printer maintenance settings, such as shading and
brightness.
Nozzle Check
A sample test pattern can be printed to test if the ink
is being correctly ejected from the print-head noz-
zles.
Head cleaning
It is possible to clean the print head.
This should be done whenever certain colours are
being printed weakly or insufficiently. Ink is used
during the cleaning of the print heads.
Head-flushing
You can clean the print head more thoroughly.
Since the head flushing uses more ink than the nor-
mal head cleaning, you should only undertake the
complete cleaning when the normal cleaning method
was insufficient to remedy your problem.
Adj.Paper Feed
If printed lines are horizontally misaligned or if im-
ages are printed unevenly, print the test pattern and
adjust the paper feed setting.
