7.2.5 Heater temperature does not going up
 Outline
If the heater temperature could not rise up to setting value or [BREAK] displayed, it is possibility of power supply
PCB burnout or fuse blowout. Blowout also can be checked by measuring resistance value at the both ends of fuse
with tester when it has difficulty with visually checking.
Heater disconnection or faulty connection, disconnection or faulty connection of control signal and Main PCB dam-
age also think as a possibility why the heater temperature cannot go up.
Follow the directions below to find out the faulty points and deal with proper countermeasure.
 Working procedure (Test)
1. Turing off the sub and main power switches in order and wait a
while to reboot the machine.
2. Operate [# TEST TEST]-[HEATER TEST] to check if media
heater is working normally.
3. When [BREAK] displayed, follow the directions below to find
out trouble point.
 Working procedure (Checking of Power Supply PCB)
1. Remove the Power Box Cover.
2. Check if no electric charge is remaining in the PCB.
Refer to the "4.5.2 Electric charge checking when replace the
head/PCB"
3. Check RLY1, 3 and 4 of the power supply PCB.
If PCB brounout as shown in the picture on the left, replace the
PCB.

[FUNCTION]
After turning off the sub and main power switches in order, unplug the power code.
Make sure to restart operation after checking that no electric charge remains in the PCB.
It is very dangerous if sleep mode functions mistakenly during the operation.
Moreover, the PCB may be damaged in case electric charge still remains inside.
Also there is a possibility of electric shock because of high power voltage applied the high-pressure part
of the power supply PCB assy. Take care to avoid contact with it.
