The HP LaserJet 1100 and 1100xi are still loved and adored by many people because of its small footprint and the use of “gravity fed” paper. It does have a few issues that HP has addressed a while ago including the use of a strange mini-centronics cable and the issue of multiple pages getting fed through the printer at once causing a paper jam. This forces the user to feed the paper through one at a time.
If you can get over these small annoyances, the 1100 series printer is a great fit for many consumers and small businesses because of the relatively inexpensive cartridges and pre-loaded drivers in XP and Vista computers making connecting to a computer a snap.

What do I do if I get a computer that doesn’t have a parallel port and what is that strange port on the back of the 1100?

The 1100 printer uses only one type of interface, parallel. It uses a slightly different parallel connection that most people may be used to called mini-centronics. For some reason unknown by many technicians in the field, HP decided to put this on many different printers ranging from the color LaserJet 4600 to the HP LaserJet 1100.  This handy guide explains the items needed and how to install an HP 1100 using a standard USB to mini-centronics connector.

What if my HP 1100 feeds in more than one piece of paper at a time?

This one unfortunately is not as easily solved as the prior question. HP released a “fix” which included a pad that you could stick down where the separation occurs. Although this helps solve the issue temporarily, it puts additional pressure on the feed roller with the increased height of the separation pad and wears that out prematurely.

The only true fix is to replace the separation pad, the side resistance pads, and the main feed roller. This process involves removing the printer side clips, main cover, and other parts to change the pads. It takes a trained technician about 15-20 minutes, but it can take a first-timer many hours figuring out how to remove the right parts and not cause damage to the printer.  Our advice is to find a good technician and have them replace the needed parts. We provide this service free with use of our cartridges and the parts are relatively inexpensive. If you’re in the Seattle area, contact us or give us a call and we’ll take care of the separation pad issue so that you can get as much life out of your 1100 as possible.
