The job is not
printed (contd.)
The photoelectric cell is not
connected to the printhead or is
not connected to it properly.
Connect the photoelectric cell correctly
to the printhead (see manual).
The optical fiber may be soiled
and has to be cleaned.
Please clean the optical fiber with a
damp cloth.
One of the optical fibers may be
damaged or broken.
Please replace the optical fiber with a
new one that works.
The optical fiber is not inserted
deeply enough.
Insert the optical fiber into the relevant
holes as far as the stop and secure with
the lever.
The cartridge is empty. Replace the cartridge with a new one.
The protective tape on the
nozzle rows on the cartridge
was not removed.
The nozzle rows on new cartridges are
protected by a protective tape. If you
forget to remove this protective tape the
cartridge will not be ready for printing.
Please check whether the protective
tape has been removed.
If the printer is not used for a
while it is possible that one or
more of the nozzles can dry out
(the open time is dependent on
the type of ink, the ambient
temperature and the air
humidity).
Remove the cartridge and clean the
nozzles. It is recommended that you
use a microfiber cloth to clean them. For
optimum cleaning results, dampen the
cloth slightly with distilled water.
The cartridge was not inserted
correctly.
Remove the cartridge from the
printhead and insert it correctly.
The contacts on the cartridge
may be soiled.
Please clean the contacts with a dry
microfiber cloth.
Printing is triggered by an
external sensor. This has been
correctly connected to the I/O
port at the back of the Videojet
8520 but has not been correctly
parameterized in the External
inputs menu of the Videojet
8520.
Please check the settings in the
External inputs menu of the Videojet
8520. The settings for the sensor in the
system settings may not match those
for the settings in the External inputs
menu.
