Question about HP 4100N: HP 4100 laserjet printer , 32MB Ram, 1200 dpi, 25 ppm speed, Network Ready, refurbished, 9...
Hplaserjet 4100 shows the error 55.0 printer error
Welcome to Fixya !
That is an iternal communications error. The first thing is to shut the printer and turn back on. If the error is still present the first item would be the firmware chip. I would remove the firmware and memory chips and reseat. Make sure you put the firmware chip back in the same slot. If that does not work, contact hp as they have a service not for firmware chip issues (not necessarily yours) and will replace it free. If not the chip it is either the formatter or the engine control board.
The Chips can be found by sliding the rear plastic panel on the right side of the printer towards the back of the printer You are looking at the formatter cage. Open the metal panel and chips are here
