(2)In case of JV300 (COM32 IO PCB)
Connect the negative terminal of the tester to the GND test
pin and measure the resistance by getting the positive terminal
touch to TP with the following.
On the Slider 2H,
TP under CN3 (TP3, 4, 5, 6, 7, 8, 9, 10),
TP under CN4 (TP19, 20, 21, 22, 23, 24, 25, 26),
TP under CN6 (TP11, 12, 13, 14, 15, 16, 17, 18),
TP under CN7 (TP27, 28, 29, 30, 31, 32, 33, 34),
Measured value of each test pin should be more than 7K ohms.
If the results for the TP group besides CN3 or the TP group
besides CN4 are not good, there is a fault in head 1.
If the results for the TP group besides CN6 or the TP group
besides CN7 are not good, there is a fault in head 2.
If any of the head COM line defect is found, the print
head may be broken. Replace the print heads first.
Connecting the normal main PCB without replacing
the broken head will break the PCB continuously.
