I'm curious about this diagnostic unit you connected. Can you share more details?


Hi Brain,

it's mainly cabling, a PCB and some jumpers so I could connect various signals to either supply or GND. Nothing fancy. I'll post a picture tonight.

When I was in the middle of diagnosing the unresponsive printer, I was contemplating to make a real diagnostic unit out of it, just for the heck of it - but then the thermo switch revealed itself before...

Here is the Laser Printer doc in full http://www.nextcomputers.org/NeXTfiles/Docs/Hardware/
Thank you !


Actually I really have to thank you for providing all these scans and other files!

Some nights, I went to sleep with a printout of the service manual in hand. And it was an unbound printout, so in the morning there was a sorting job to do Smile

I had some success. Found a utility named printer preferences ("PP") on a NeXT PD-CD. It show the status of the printer and allows to make some settings.

After I fed the printer with fresh paper it started to print but would not be able to pull the paper through (exept for one time).

Here is an interesting maintenance video for the printer: https://dl.dropboxusercontent.com/u/1429222/Videos/nextprinter.mov (can somebody copy it to the file area?).


Hi

where can I find the utility named printer preferences ("PP"), please help
