7.2.5 Heater temperature does not going up
Working procedure (check disconnection)
1. Check the heater disconnection and faulty connection.
Measure the resistant value of heater BOX junction cable 1
using tester probe. (refer to a picture on the left)
Measured resistance value has no problem if the value is in
range as below.
• Rear heater (Blue) : 190-240
• Print heater (White) : 120-160
• After heart (Black) : 110-150
2. Check disconnection and faulty connection of Heater control
signal.
Measure the resistance value using PC (Photocoupler) of power
supply PCB and CN5 of the main PCB.
Following diagram shows measurement place and value.
Working procedure (Checking of Main PCB)
1. If all procedures did not work to solve the problem of tempera-
ture rising, it is a possibility of damage in Main PCB.
Replace the Main PCB and recheck if temperature enables to
read correctly or not.
