HP LaserJet 2100TN grabs multiple sheets of paper
Hi all,
My lab has an HP LaserJet 2100TN printer (b&w, networked, manufactured Aug 2000) which recently has the annoying habit of frequently grabbing multiple sheets of paper from the tray. So, for example, I printed out about 15 pages this morning and ended up with 30-40 pages on the output tray, most of which were blank. Sometimes when it grabs multiple sheets, one of them slips off and causes a paper jam. So it can be more than just a minor annoyance. Anyone have any tips on where I should look inside to fix this problem? Thanks! Dan Lenski University of Maryland PS- This printer also has an incredibly slow and buggy Java-based configuration web page, but I don't suppose there's any way to fix that :-( |

Anyone have any tips on where I should look inside to fix this problem? Usually that's a worn separation pad. Depending on which tray, maybe #14 on this diagram: http://www.printerworks.com/Catalogs...PaperTray.html Or #1 he http://www.printerworks.com/Catalogs...nalComp_3.html You might be able to rough up the existing pad enough to get it working while the replacement part is on the way. I can't recall what the 2100 pads are like. Platen cleaner can work on rubber pads, don't know about cork. Sometimes just wiping the pad with your finger will clean off dust and get it working temporarily. PS- This printer also has an incredibly slow and buggy Java-based configuration web page, but I don't suppose there's any way to fix that :-( Telnet to the printer instead, although there are some JetDirect settings that can only be set through the web interface. You really shouldn't need to use either very often, most of the settings are set-and-forget. -- Warren Block * Rapid City, South Dakota * USA |

I see you have a TN printer, so is it tray 1,2 or 3 that gives problems? The pads for this printer are a rubber like compound and the one in the cassette tray (tray 2 or 3) are simple to replace. They are also readily available from several sources. The pad in tray 1 (multipurpose tray) is a little harder but not in the category of difficult, you need to remove some covers. The only advice I feel is important is if you are going to replace the separation pads you should consider replacing the feed rollers as well, there is one pad and one roller for each tray. When the pad in a particular tray starts to give trouble the roller usually follows soon after. Replacement of the pads and rollers is detailed in the service manual which is available free from http://www.image1products.com/techdocs/HP.htm You can look to see what is involved in the manual. Humidity and paper condition is a possibility but in my experience rarely causes multiple feeding provided you are using a good quality paper (any of the major brands are fine for this printer).
