Resetting Purge Or Flushing Counter - Brother MFC640CW Service Manual

607. When the purge or flushing counter approaches 6400 or 403645833, respectively, the
"MACHINE ERROR 46" appears, and further purge or flushing operations are prohibited.
Replace the ink absorber box or flushing case, and then reset the purge or flushing counter with
