JV33 Precautions of replacing PCB
1. Overview
This document describes to determine whether a problem is caused by a damage of the PCB ASSY
related to a print head control. If the problem mentioned below occurred, it is necessary to check
condition of the damage of each part (ASSY) since the PCB could have been broken:
(1) All nozzles or nozzle line of each color would not fire. Nozzle drop out would be caused by a
certain scanning position.
(2) The printer would not be turned on. Nothing would be shown on LCD even if turning on the
power.
(3) Occurred "ERROR 07 VOLTAGE" or "ERROR 07 HEAD 0"
(4) Occurred "ERROR 09 HDC ERROR"
(5) Occurred "ERROR 200 HEAD MEMORY"
(6) Occurred "ERROR 50 MEDIA DETECT"
2. Tools to be used
Digital tester (or analog tester): it is used for measuring resistance and DC voltage
