Sounds like a heat, thermal issue. You may have a non- functioning cooling fan somewhere inside. There are several of them so don't be fooled if you hear one of them running. Same issue happens with CPUs on PC computers. Will suddenly shut off if too hot.

These equipments use a sbc492 by Aaeon motherboard, and usually they shows a message like "Cmos battery Low".These motherboards use an RTC M48T86PCI with a internal lithyum battery, and just replace that component.Other problems may occur, like damaged slots, and or oxidation, but generally the 486 architecture is a huge way to work,Only clean change the memory(dimm 128 x 100mh)and enjoy.A simple way is a replacement with a new one by Intel, still easy to find in some inventorys, i have many in USA who can suply.

hope to solved

The focussing wheels are in the middle of the hinged mount - rotate them until the image is in focus.

The issue can be resolved by doing a printer reset. Make sure that you follow the instructions on the user manual to reset the printer correctly.
