Hp HP LaserJet 4100TN

hp laserjet 4100tn hangs during initialisation


i've got a problem with my hp laserjet 4100tn. during poweron the printer hangs during initialisation (stops with two rows of asterisks). i've performed the engine test successful and also replaced the formatter board incl. dimm rom + ram. but still the same error.

thanks for any tips :-)
Pull the JetDirect card out and see if it still does it. You have to leave power off about 10 minutes with the card out before powering it on to clear the error code.

i don't got a jetdirect card installed - muffer
That is usually caused by a bad formatter or bad firmware dimm. Make sure the firmware dimm is in the correct slot as it will only work in the one slot marked rom.

i agree. but i've exchanged the formatterboard incl. firmware dimm (j1) from a working printer - just for testing. and i got the same failure (asteriks on the display)

Then check the cable which runs from the formatter connection to the main board at the bottom. Also are you using the same memory chip with the exchanged formatter.
