This is the simplest problem I've ever seen in all printers I fixed, And= the dumbest one. HP when doesn't do it in the entrance, does it in the= exit ;o) This printer has the fuser controlled by an SCR. A BT136 or something.= This BT is not heatsinked. So it fails. And gives this error you are= seeing. Step by step to fix: 1 - open the printer, and remove the external plastic "skirt", taking off= 4 or 5 screws around it inside the printer 2 - disconnect the control panel (only one IDC connector) 3 - pull off the power supply - the big box on the down right 4 - pull off the filter assembly - the black box with green tabs 5 - pull off the AC unit, on the top right. That's where the AC enters 6 - dismantle the AC unit, change the SCR (please, be gentle and put a= small heatsink on it) and reassemble You have a new battletank ;o) I've fixed some 100s of HP2 and HP3 printers with the same problem. That's= the only thing that happens on these printers, beyond fuser destruction.= Nice printer to have! ;o))) BTW, I need the A4 paper cassete and the fuser assembly or only the fuser= roller (the one covered with teflon) of the HP3. In USA it seems to be= trash, in Brazil it is expensive to the hell! Maybe some friend from the= list have a spare around ;o))) My HP3 became a dead brick, and I miss her= working :o((( ---8<---Corte aqui---8<---- Alexandre Souza taito@terra.com.br http://planeta.terra.com.br/lazer/pinball/ ---8<---Corte aqui---8<---- -- http://www.piclist.com hint: The PICList is archived three different ways.
