Maintenance Unit Cleaning Cycle
You can start the cleaning operation at either:
• The printer driver (computer)
• Operation panel (printer)
You can set the print head for cleaning (or clean them all) if you start the clean job
with the printer driver. All the print heads get cleaned if you start the clean job from
the operation panel.
An example of cleaning the Black “K” Print
Head:
Cleaning starts with the carrier and print
heads [A] capped and resting on top of the
maintenance unit [B].
When the cleaning cycle starts, the
maintenance unit [C] is lowered by the
rotation of the main shaft. Then the cams
rotate away from the bottom of the unit.
At the same time, the carriage [D] moves
to the left.
The carriage moves the print head
(in this example, "K" the black print head)
above the first vent [E] of the
maintenance unit.
NOTE: Only the first vent can siphon ink.
Another cam on the main shaft presses
the maintenance unit up so the print
head (K) covers the first vent.
At this time the maintenance motor reverses.
The one-way clutch disengages the main
shaft and engages the second shaft.
This operates the tube-pump. The suction
from the pump below sucks ink [F] from the
surface of the print head.
