Automated Print Head Cleaning
Before performing the Automated Print Head Cleaning procedure check the print
head guard slots for any foreign objects that maybe deflecting or blocking the ink
while in flight.
Automated Print Head Cleaning is performed on operator command from the front
panel. From time to time it may become necessary to perform a cleaning routine to
purge air or clear clogged print head nozzles.
There are two cleaning levels to choose from for each print station. Level 4 is more
aggressive than level 3 cleaning and it will therefore take longer to perform and
consume more ink. They are:
Level 3
- Med. Level Cleaning – 15 Cycles.
Level 4
- High Level Cleaning – 20 Cycles. (Also used for priming a new
print module).
NOTE
: Each cycle moves 0.3mL of ink from the supply bag into the waste
bag. A new supply bag has 110mL of ink. The machine will shut
down the module pump when 30mL of ink has been pumped into
an ink cartridge waste bag. The balance of new ink in that
cartridge’s supply bag can be consumed by printing.
See the Front Panel Menu map for the location of the default cleaning levels.
WHAT LEVEL TO USE:
•
Level 3
- is used when few nozzles will not print.
•
Level 4
- is used when level three will not clear all nozzles, and for new print
modules, to purge the heads of analog / air and fill them with ink.
Once the default level of your choice has been selected for the print station to be
cleaned return to its Clean Station screen and press the Enter button. The machine
will then generate a vacuum on the print heads in that print station. This will cause
ink to flow from the supply bag through the print heads and into the waste bag
purging the print heads of air / foreign objects.
