Error Code
(Hex)
43 Head thermister broken.
44 Head thermister short-circuited or error in its related
parameters stored in the EEPROM of the driver PCB
45 Flushing operation abnormally ended. (The head
temperature has arisen abnormally.)
46 The number of performed purge sequences has reached
the limit.
47 Head parameters stored in the EEPROM are invalid.
(This code may appear only in the maintenance mode.)
48 Weak connection of the head flat cable M (main-head
power line).or W (driver-head signal line)
4D Error in the head drive voltage parameter stored in the
EEPROM but not accessible at the user site.
(This code may appear only in the maintenance mode.)
4E Out of the allowable range of the head drive voltage
designed for individual print head properties.
(This code may appear only in the maintenance mode.)
50 The purge cam HP switch does not come ON even after
the purge cam has been driven by the specified number
of pulses.
51 The purge cam HP switch does not go OFF even after the
purge cam has been driven by the specified number of
pulses.
52 The pump switching cam HP switch does not come ON
even after the switching cam has been driven by the
specified number of pulses.
53 The pump switching cam HP switch does not go OFF
even after the switching cam has been driven by the
specified number of pulses.
7D Any of the ink dot counters has counted up to the
specified number of dots, meaning the end of the head
service life.
7E No head parameters stored in the EEPROM.
(This code may appear only in the maintenance mode.)
