MX-B200  SIMULATION, TROUBLE CODES  10 - 24 H4 00
ContentHeat roller low temperature detection
Detail 1) When the target temperature (165°C) 
is not reached in 55 sec after starting 
warming-up.
2) When the temperature below 100°C is 
detected for 300ms under the ready 
print state.
∗Starting warming-up means not only 
that in power supply but also reset that 
in reset from shut-off and in side door 
close. (The timing of generating H4 is 
not limited to that in power supply.)
