Paper jams on HP laserjet 3/4/5 printers are almost always caused by a good looking takeup roller that cannot grip the paper.

The only thing I can think of is that maybe the pickup roller isn't releasing the papaer soon enough causing the first roller in the paper feeder not to feed the paper far enough. At least on the LaserJet 3 series the pickup roller and pad wear causes them to not be able to push hard enough on the paper to get it to the next roller. As the roller ages it hardens and rubbing against the paper causes wear that makes it smoother and smaller. Those rollers are considered regular maintainance items (But on the LJ3 you still have to take half the printer apart to change it...). You can usually find cheap replacements on EBay, often with instructions. Quick fixes that might help temporarily are light sanding and/or cleaning (Probably what the WD40 does). -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |

Andy Cuffe Hi Andy, I am not being sarcastic, and I am not trying to wreck your printer. I am only telling you to do, what I do myself. I have been doing this to HP printers for about the last 10 years, so I know both the short term results, and the long term results. The WD40 soaks into the rubber and gives it the slight tackyness that is necessary to reliably pick up the paper. The important compound is not the stoddard solvent, but the yellow stuff is that is in WD40. Email me, and I will send you my ham call and phone number. You have to remove the "-" signs and everything in between them to get my correct email address. -Chuck Harris |

Anyone have any ideas? Andy Cuffe Andy, Have a look at the tray balancer mechanism. There is an arrow on the tray and a "floating" arrow on the mechanism. The arrows should be pointing at each other. Sometimes debris can get under the pivoting part of the tray and it'll bind, causing a no-feed paper jam. "Reconditioning" the roller is usually good only for troubleshooting purposes and never lasts long-term. A new roller for that tray runs about $10, a worthwhile investment if everything else is in good working order. I just use tap water and a nice abrasive cheap paper towel. I hope this info helps! -k |

I have had rollers that would not feed even one sheet last more than 2 years between treatments with WD40. My taste in printers is generally around that long. -Chuck Harris |

I have been buying Moe's Magic Printer Roller Reconditioner and it can't be healthy stuff to inhale... some kind of rubber solvent I guess. BTW, I highly recommend Moe's fixyourownprinter.com to the OP and anyone else. He is an extremely knowledgeable and helpful guy and his site has a wealth of information. -- Nelson |

Kibo informs me that Chuck Harris stated
that: [poor paper feeding] Paper jams on HP laserjet 3/4/5 printers are almost always caused by a good looking takeup roller that cannot grip the paper. The symptom of that problem is 100% of the time the paper not quite reaching the first feed roller. Using WD40 sounds counter intuitive, but it works! It took a great leap of faith for me to try it the first time (on the recommendation of a friend who deals in surplus printers), but I did, and it works perfectly. Back when I did this for a living, I used acetone (paint thinner or nail polish remover) on the same roller to restore the grip. Apply with a cloth, in the same way that Chuck described. The reason it works is that the suface of the pickup roller eventually hardens & loses its tackiness, resulting in it slipping on the paper instead of gripping it. Cleaning the roller with solvent removes the hardened surface, restoring the gripping surface. The same method works well on the separation pad, when you get the problem of the feeder picking up multiple sheets instead of single sheets. -- W . | ,. w , "Some people are alive only because \|/ \|/ it is illegal to kill them."

I can be reached at I would think that a driver is supplied with Windows on such a (once) common printer; It does. And any similar vintage HP model driver will work as well, although you may need to experiment to find one with matching paper tray options. The generic drivers also tend to be more reliable than the 'special' ones HP supply on their driver disks anyway. -- W . | ,. w , "Some people are alive only because \|/ \|/ it is illegal to kill them."

look for a missing paper guide? The laser jet 5 can fail in
that way if the paper guide at the output of the pickup roller is missing... or so I have read. The paper buckles and misses the feed roller. -Chuck Andy Cuffe wrote: Well, I jusr replaced the pickup roller and it's still having exactly the same problem. The paper falls about 1/2" short of the first feed roller inside the printer. I guess I'm going to have to look for a problem with the large capacity feeder mechanism. Andy Cuffe |
