7. Checking damage of the Ink slider PCB
(1) Remove 6 FFC at CN1-CN6 on the Ink slider PCB.
(2) Measure resistance between 3.3V pattern and GND pattern in Ink slider PCB and judge whether
it is good or not with List 4.
* Connect the Negative terminal of the tester to the GND test pin (TPG1-4) and measure the
resistance by getting the Positive terminal touch to 5-8 pin of CN3.
* In the case ERROR 200 or ERROR 50 occurred even if replaced the print heads, it is highly
likely that U1 (CPLD, E600074) of Ink slider PCB is damaged.
