Print Head Maintenance
Daily / Shift Startup / Periodic
Wear safety goggles when working with industrial inks or solutions!
The majority of print quality degradation is due to excessive debris deposits on the
print head orifice plate that disrupt the ink droplet path. For best preventative main-
tenance practices, do the following:
•
Pause or stop the message to avoid any misprinting. It’s OK to leave the system pow-
ered up during this time.
•
Remove excessive debris build-up (corrugate dust, glue strands, and the like) on and
around the front of the print head by using maintenance spray n-Propanol (5760-695)
on a clean lint-free cloth (6600-171) and wiping the front plate and enclosure. If debris
build-up is noted on the enclosure and rear of the print head, then wipe those clean,
too.
NOTE: DO NOT SPRAY N-PROPANOL MAINTENANCE SPRAY DIRECTLY ON THE
PRINT HEAD OR ANYWHERE NEAR THE ORIFICE PLATE
.
•
Using a sponge swab (5760-832), rub the orifice
plate lightly from top down in a vertical direction
while ink is flowing during an A
P
S (Automatic Prim-
ing System) cycle. The APS button is located on
the rear of the print head. DO NOT USE mainte-
nance spray directly on the orifice plate.
•
Press the APS button one more time to ensure
channel priming, but do not swab this time.
•
Wipe the front plate with a clean lint-free cloth to
remove any excess ink.
Annually
•
Replace the vent filter on the res-
ervoir.
•
Depending on desired quality of
print, print heads may need to be
returned to the factory for a thor-
ough cleaning of the print engine
due to excessive debris lodged in
the orifices
