Here’s a cool DIY on how to dismantle your broken or old laser printer. Although you might not
be able to fix your laser printer, this is a very good DIY as a reference while hacking your
old laser printer.
I recently got a used laser printer (Canon LBP-4) from cit since he moved to Regensburg and sorted out some surplus hardware.
Having ordered a new toner for 23 Euros I had to notice that the printer is broken
The Display said 52 SERVICE and google told me that it’s probably the motor of the laser scanner.
So I grabbed the screwdriver and had a look into the printer.
outdated, but solid hardware
Some time ago they built hardware bigger, rugged, modular and with no SMD parts. Thus fixing stuff was easier.
The printer is such a piece of hardware consisting of modular non-SMD electronics. There are separate and removable circuit boards for parallel port interface, postscript processor and the printer control.
