Maintenance
Startup Procedure
At the beginning of each shift, perform the following tasks:
1With the spray cap on the solvent bottle, spray the nozzles with
solvent. In harsh environments, you may need to spray the nozzles
more often than once per shift.
2Purge the printhead.
3Check the ink level in the bottle; install a new bottle if necessary. In
harsh environments, or if print quality declines, replace the ink bottle
with solvent and purge solvent through the unit.
Shutdown Procedure
If you are shutting down a porous unit for less than two weeks, simply
turn off the controller. You do not need to purge the printheads with ink
or solvent. Also, do not remove any ink that may have caked on the nozzle
block. This will keep contaminants from entering the nozzles.
When you restart the unit, follow the daily maintenance procedures on
“Startup Procedure” on page 2-1.
If you are shutting down a porous unit for more than two weeks purge the
printheads with porous solvent. Leave the solvent in the ink lines until
you restart the unit.
