HP Latex 570 79:04 error help Please.

[Steven.Cao]

Summer is coming, 25-29 °C inside the warehouse.

I have a lot of 79:04 errors since last month, it sounds like something wrong with the maintenance tank, something is stretching the printhead carriage during the printing, then printer stop and error reports. I have tried to replace new maintenance tank, no luck.
The printing is ok when it works, just I don't know when it will stop during the job.

one post @ HP Latex Knowledge Center suggests to replace the SSD.

Any suggestion please.

Thanks in advance.

Is it the only error you get? Do you have latest firmware installed?
Do the hard disk recovery from diagnostics.

I don't quite understand what you mean by "something is stretching the printhead carriage during the printing"?

The error happened when the carriage moved back to right, and the maintenance wiped the printhead, there was a loud sound from the right part of the printer, like a paper jam, but I didn't find any debris in the way of carriage.
The firmware STORM_00_13_07.1 was installed 12-2021, it worked well until last month.
The only error is 79:04.

Clean your encoder strip well. Check the condition of the trailing cable.

I'd start by removing heads and rebooting.
Then put heads back in.
I suspect a head has gone faulty.
This process should show you which one.
