27: Recommended Maintenance
The EnduraINK DTx inks used in the PrismJET DTx are very forgiving and less prone
to clogs than solvent based ink. However, if the PrismJET DTx is not maintained
properly, or used often, the inks in the print head may eventually dry up, causing
your nozzles to stop firing. This is a very serious matter, as this could ruin your print
head.
Because clogged or misdirected nozzles are almost always due to a lack of proper
care and usage, clogged or misdirected nozzles are not covered under warranty. A
print head failure caused by lack of use or improper maintenance may not be
covered under warranty.

Proper use and maintenance. The best way to maintain your PrismJET DTx is to use
it regularly. Even if there are no jobs that need to be printed, simply turning the
machine on, running a nozzle check, and allowing the printer to go through all of
its actions will cycle ink through the print head and capping station, thus prevent-
ing ink from drying in the print head. This should be done at least once per week.
This will cost a very minimal amount of ink and media, and will keep your machine
printing at its full capability. See section 10 on page 31 to learn how to print a
nozzle check.
Consumables. On the PrismJET DTx, all parts that are involved in ink flow are con-
sidered consumables or replaceable parts, and are not covered under warranty. This
includes the print head, maintenance assembly, and all pads.
Ink Pads
There are a total of 3 replaceable ink pads on the
machine.
1) Upper Spritz Pad: This pad is located inside
the printer to the left of the heat platen. Dur-
ing printing and head cleaning, the print head
releases small amounts of ink onto this pad. As
this pad is used, it will become saturated. When
this happens, the head cannot use the pad cor-
rectly because ink will splash back onto the head.
This ink can then be carried across the platen and
dropped on the media potentially marring or ruining a print job in progress.
During regular use, the upper spritz pad can become saturated roughly once per
week. When this happens, it should be replaced as soon as possible to restore
proper function of the head and wiper blade. The part number for the replacement
pad is PRNA-DC-PT-1900-M048
