HP Recommended
Product: Laserjet 4100


Printer HP Laserjet 4100.
No network card, no internal harddrive.

Printer was working well, problem came up on sending a print job to the printer.

 

Problem: on startup, after switching on, fan starts, engine starts, display
counts memory up to 32 MB. (installed quantity)
After reaching that value, engine stops, fan seems to stay running (outlet on the
left side of the machine still sucking).
Display shows 32 MB on the first line, added with asterisks and the second
line are asterisks too.
The 'ready' text does not come up.
None of the buttons on the panel gives any reaction.
Trying a cold reset ('go' and switch 'on')  gives no reaction on display.
The engine test (pin in small hole on the left side, kept there) produces a
sheet with lines.
Took out the ram-module and switched the printer on: the display shows
53.10.03, which looks okay for the situation.
Reseated the ram in the same slot again.
Took out the rom-module (which looked okay too) and reseated it.

As the printer is in good condition, and i love to use it again, my questions:
-does this all point to a bad formatter?
-would a new/other formatter cure the problem?
-can i switch the rom and ram module to another formatter?

-is the c4169-67901 the correct replacement?

Thank you for your input/help.
