4-3-1. Electrical Troubleshooting

Outline
The following errors will be caused by breakage of PCB, and some of them may also break the surround-
ing PCB by breakage of the head.
This explains the causes and handling for the electrical troubles.
Related troubles :

• The power would not be turned on
• ERROR 07
• ERROR 50
• ERROR 200
• ERROR 202
• ERROR 205
• ERROR 207
After turning off the sub and main power switches in order, unplug the power code.
Check if no electric charge is remaining in the PCB.
Refer to the "4.5.2 Electric charge checking when replace the Electrical Parts"
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.
Causes and solutions of the print head breakage
Cause of head/PCB damage
1
Disconnection of HDC_FFC
2 Disconnection of Head FFC and contact failure
by wrong insertion of FFC
HEAD or VOLTAGE
MEDIA DETECT or MEDIA POSITION (Only of JV33)
HEAD MEMORY
DEVICE CONSTRUCTION
47V HEAD VOLTAGE (Only of CJV30 and modified JV33 PCB)
SLEW RATE or OVERFLOW or UNDERFLOW
Fix moving part of the HDC FFC
