30: Cleaning and Flushing the Print head
Cleaning: These instructions are for manual cleaning of the bottom of the print head. This is only
necessary if there is a clog in the nozzles which normal cleaning cycles have not resolved.
See section 11 - page 32 - for instructions on running normal cleaning cycles.
30.1
30.2
Flushing: If wiping the head and running
several cleaning cycles has not unclogged the
nozzles and restored perfect printing, it may
be necessary to flush the head by removing
the ink cartridges and forcing a small amount
of CS3 cleaning fluid through the channels.
This should only be done in the case of a seri-
ously clogged print head and only after
having contacted SignWarehouse
Technical support.
Before you begin, it is a good idea to place
some paper towels in the area beneath the
print head to absorb spent ink and cleaning
fluid (Fig 4).
Fig 1. The bottom of the print head is vis-
ible through the front service door once
the maintenance station is removed.
Once the maintenance station assembly has
been removed, you have clear access to the
print head (Fig 1). If ink has accumulated on
the bottom of the head this can be removed
by gently, but firmly wiping the bottom of
the head with a lint-free cloth or mainte-
nance swabs (Fig 2)(PRNA-FS-LT00012510 )
saturated with 99% isopropyl alcohol or
EnduraINK CS3 Cleaning Fluid (PRNI-DC-CS3-
BOTTLE).
DO NOT USE any other cleaning solutions to
treat the head or maintenance station. Use
of cleaning fluids other than EnduraINK CS3
may result in contamination, clogging and
failure of the ink delivery system. Treat the
head until there is no visible ink residue on
the swab or cloth (Fig 3). Then reinstall the
maintenance station assembly, run three
cleaning cycles and print a nozzle check.
