Replace the Spit Catcher Foam Pad
Introduction
The Spit Catcher consists of a slotted cover for the Maintenance Station
drawer and a foam pad that is held in place under the drawer. The Spit
Catcher is necessary for IJC255 white ink and also for all five of the newer
Océ IJC256 inks. These inks require a small jetting actions (“spitting”)
between printing times to keep the printheads in a ready-to-print state.
This spitting action uses very little ink but does require that the operator
clean the maintenance tray cover more frequently.
Purpose
Over time and with use, the inks can develops particles that can interfere
with the internal jetting action of the nozzles in the printheads. If the flow
of ink is restricted, print quality can be reduced. Therefore, for the inks that
require it, spitting happens on a regular basis. A foam pad located on the
underside of the maintenance drawer absorbs this small amount of ink.
NOTE
Although the carriage is oriented so that the nozzles spit into the slots in
the spit catcher, some ink will find it way onto the flat surface of the
maintenance station drawer. Check the surface of the maintenance station
when you perform the daily printhead maintenance. If you see any ink
wipe it up with a clean cloth or paper towel.
When to do
Spitting only jets a small amount of ink, but eventually it will accumulate in
the foam pad to a point of saturation. This is a consumable item so see
your local sales representative to order it.
NOTE
Be sure to keep the maintenance drawer closed (except when you do the
printhead maintenance) so that exposure to light does not cure any
accumulated ink.
Procedure
1.
Slide the maintenance drawer out from under the carriage.
2.
Reach under the end of the drawer and pull on the spring-loaded knob
while you hold the spit catcher metal base in place.
3.
Swing the metal base on its bracket part way down to reveal the pad.
