Similar to bronxteck I found one of the resistors on the main PCB (on HE-4, right printhead) was open. I replaced the resistor. The heads are both new (but still saw the old resistor). Now after this replacements I can do a nozzle check via the service mode and I get an Ok for all channels. Also, checking the the head voltage (HV) during the nozzle check results in a reading 24.0V on the multimeter. Therefore I assume, the heads are in good condition, controlling them works and the PSU is fine. Still, if I try to print anything, I get a 2F48 error.
The weired thing is, that when I try to print anything, the PSU does not even get a signal to raise the HV. Therefore, I am asking myself, why the CPU does not raise the HV enable line? Has anyone experienced something similar? Is there any check done before the HV enable line is raised which might be failing?
Please don't tell me to replace the Main PCB. This I might do this, but only if I fail to find the rootcause of the issue.
