If you REALLY want to solder it, just for old time's sake, great. The other route is to go to partsurfer.hp.com, enter the model number of the laser jet, and then look at the parts list. You will have to enter your country before it will give you a list of parts. Once you find the exact pn you need, do a Google or similar search, and the parts can usually be obtained for very little. I have a color laserjet here in good working order, probably needs new pickup rollers from sitting, but they are VERY unwieldy to ship. Are you anywhere close to Texas?

Fred noted: I'm not entirely sure. 60/40 solder melts at around 360, so I was putting a bit of a fudge factor in for lead free. There's few standards (or too many) for lead-free solder, it seems. Would thinned rosin flux work? Alexandre - the earlier LaserJets are and were very good, up to about the 4000 series. Since then it's been much more hit and miss. Quite coincidentally they also shifted production to China, but I'm sure there's absolutely no connection. ----- No virus found in this message.
