4-3. Detailed Methods of Coping with the Malfunctions
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 :
• Abnormal firing (simultaneously firing of no firing from a certain nozzle line)
• The power would not be turned on
• ERROR 07 HEAD or VOLTAGE
• ERROR 50 MEDIA DETECT or MEDIA POSITION (Only of JV33)
• ERROR 200 HEAD MEMORY
• ERROR 202 DEVICE CONSTRUCTION
• ERROR 205 47V HEAD VOLTAGE (Only of CJV30 and modified JV33 PCB)
• ERROR 207 SLEW RATE or OVERFLOW or UNDERFLOW
Causes and solutions of the print head breakage
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.
Cause of head/PCB damage Countermeasures
1 Disconnection of HDC_FFC Fix moving part of the HDC FFC
JV33: Please fix FFC of following machines. Please refer to "JV33 Quality Infor-
mation No.14" (Japanese only) to fix the FFC.
CJV30-130 : from G0704001 to G0805345
CJV30-160 : from G1704001 to G1805329
Please refer to the documents below for more detail.
2 Disconnection of Head FFC and contact failure
by wrong insertion of FFC
When replacing heads, replace the Head FFC ASSY as well. Insert the FFC straight
and visually check if they are attached without misalignment.
Also the function to check the connection of heads when turning on the printer has
been added from following firmware version.
JV33-130/160/260 (TS3) : F/W Ver.3.20 or later
JV33-130/160/260BS : F/W Ver.3.00 or later
If [ERROR 202 DEVICE CONSTRUCTION] occur, it might be a FFC trouble or
head/PCB may be damaged.
Please refer to the documents below for troubleshooting.
