Purge types, ink usage, purge counts, and purge codes
Purge Types
Head replacement This is a specially prepared
purge purge for eradicating mixed
(See Note below.) color inks.
Normal purge This purge operation
removes dried ink sticking
to the head nozzles.
Periodical reset This purge operation
purge removes air bubbles that
have accumulated in the ink
supply tubes.
Power purge More powerful than a
periodical reset purge, this
purge operation is for
removing stubborn clogging
from the head nozzles and
ink supply tubes.
Initial purge When the user loads ink
(See Note below.) cartridges for the first time,
this purge operation
automatically runs to refill
the ink supply tubes and
print head with fresh ink.
User reset purge This purge operation should
be performed if the print
quality problem persists
after a user has performed
the purge operation
repeatedly by pressing the
Ink (Ink Management)
key.
Engine setup This purge operation refills
purge the ink supply tubes with ink
when there is no ink in those
tubes.
The above information is as of May 14, 2008.
(Note) If the head/carriage unit is replaced with a spare part having a round, blue seal on its left side
(shown in Appendix 1, "(2) Head property
with the one having no seal, perform the initial purge.
This machine counts all purge operations and flushing operations performed since produced in
order to prevent the ink absorber box and flushing box from overflowing with drained and
flushed ink, respectively. An initial purge, for example, advances the counter by 155 + 331 =
486.
When the purge or flushing counter approaches 12480 or 619318182, respectively, the "Unable
to Clean 46" appears, and further purge or flushing operations are prohibited. Replace the ink
absorber box and flushing box, and then reset their counters. (Refer to the next page for the
reset procedure.)
