Tip: 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
140 + 332 = 472.
When the purge or flushing counter approaches 12480 or 619318182, 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.
