6. Is the Centro cable firmly connected
between the Cenntro PCB Unit
(CN101) and the Main PCB Unit
(CN18)?
7. Is the print head cable firmly connected
between the Head SA and the Main
PCB Unit (CN4)?
8. Does the transparent/reflective sensor
detect presence of media?

Poor printing
1. Thickness adjustment is improper.
2. Is +24V supplied to the test point T18
low?
1. Adjust the media thickness
adjustment dial to suit to the media
thickness being used.
2. Replace the Power Supply Unit.
