HP Latex 360 03:10 error and 12.21:10 error

[Steven.Cao]

The HP Latex 360 with 3L ink supply stops working.

It shows error 03:10 when it powers on. the blue and the amber light on the PSU is on. After I switch the PSU from a working L360, It shows another error 12.21:10. Print Mech: 24V to Veridian Open Circuit, then another error 01.12:10.

When I put the PSU to a working L360, that L360 shows error 03:10. So the PSU must be dead. What should I do next? try the Print Mech? Curing Control PCA?

Thanks.

Well if you read the manual it tells you to first replace the Printmech and then PSU.

But anyways if you have a known good working setup, transfer the Printmech from that and test it. PSU as well if it's not working.

system load 1%, new error: 12.2:10 Print Mech: 24V to Verdian Failure,
then around 29%, error: 01.12:10 Curing Control PCA Failure.

I think the good PrintMech is not working now. No more good working parts

Might be, maybe the PSU blew it, who knows.

After many tries, the printer damaged 2x Power Supply Unit, 1x Heater Control Unit. 5xPrintMech Board.

No. F14 SMD on the PrintMech Board is keep failing. it turns out that rainwater leak into the foam which is attached to the back of curing modules cover. that damp foam cause the short circuit when the PrintMech Board try to switch on the Curing Heater during the initialization power on process.

The water must go in there during shipping without proper waterproof packing.
