How to remove error e3 in hp laserjet m125a - HP Office Equipment & Supplies

It seems like you've tried several troubleshooting steps to resolve the issue, but the problem persists. A common cause of black pages with a laser printer is a faulty toner cartridge, but since you've tried replacing it, it's unlikely that's the issue. Another possibility is a problem with the imaging drum or the transfer roller, both of which can cause black pages. You may also want to check the toner supply system, including the toner level sensor, for any clogs or blockages that may be causing the problem. If these steps don't resolve the issue, it may be necessary to seek further assistance from a professional repair service

Have you tried a different USB port? May be a device conflict, so you may need to disable other devices using that port...

79 errors are often fatal. Your only hope is to get it back to READY, then update the firmware before it reverts back to 79 ERROR. The other option is to replace the formatter, but it would be about the same cost to replace the whole machine.
