Cleaning Clamshell Star Wheels
As the printed media travels from the print area towards the exit end of the printer, it travels under the Star Wheel
Assembly [B]. This assembly contains many pointed (starred) rollers/wheels that are designed to keep the printed
media from making contact with anything that could smudge the wet image. The Star Wheels are designed so they
can travel over the wet image with minimal ink offset results. In some cases, Star Wheel contact may produce a
pattern of small dots, in the direction of media travel. Over time these Star Wheels will gather ink and debris,
reducing their performance. They will need to be cleaned routinely.
Routine Operator Maintenance:
1.
Open the Clamshell to access the Star Wheel Assembly
[B]
2.
Using a damp cloth, carefully wipe the Star Wheels and plate.
IMPORTANT:
Only wipe Wheels in the direction they roll [C]; never across the Wheels.
3.
Dry the Star Wheels and plate with a clean, lint-free cloth
.
4.
Close the Clamshell.

Cleaning Ink Revolver Couplings
To reduce the chance of coagulated ink and debris entering the Ink System, causing possible ink flow and nozzle
clogging issues, clean the Ink Revolver Couplings before installing/reinstalling the Printhead.
1.
With the Printhead Cartridge removed, moisten a foam tipped swab in
distilled water.
2.
Insert the swab into one of the ink revolver openings (ink channels)
and rotate swab to clean chamber.
3.
Use a new swab for each of the remaining ink revolver opening until
all 10 openings are clean. (
5 on each side.
)
CAUTION
: Do NOT reuse the same swap in multiple ink revolver
openings, as this may cause color mixing.
