[ 5 ] Purge types, ink usage, purge counts, and purge codes
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 labels" ), perform the head replacement purge. If it is replaced
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 133 + 316 =
449.
When the purge or flushing counter approaches 7360 or 568181818, respectively, the
"MACHINE ERROR 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
Chapter
9, Section 9.4.24 "Purge Operation (Function code 76) (User-accessible)," for the reset
procedure.)
