Question about Ricoh GelSprinter GX7000 Printer
It's not the paper actually misfeeding in the printer, but appears to be the print head causing the issue. The print head assembly tries to make a fast move on the rails and comes to a screeching halt before going back to what it previously was doing. It is akin to the print head either losing it's place from the encoder strip or over-taxing the CR (carriage return) system by over-voltage/over-current. The print head assembly rides with what appears to be two "oil-lite" type bushings on a smooth steel rail on the back side and a simple Teflon tab on the rail on the front side. I've cleaned the encoder strip on several of these printers and sometimes that is the culprit. More often than not, cleaning the encoder strip doesn't help. The print head still jams on the rails. I've cleaned and polished the back rail, cleaned the bushings and the surrounding areas, cleaned the encoder strip sensor at the back of the print head assembly and none of this shows improvement concerning the print head jamming. I don't have any new spare parts, but am more than willing to find some, to keep some of these workhorses alive a while longer. Some of these Ricoh 7000 printers have run over 200,000+ 8-1/2" x 11" sheets without this issue. Some run less then 30,000 and these jams appear. I don't know what the MTBF is for these printers, but it varies wildly in practice. Anyone have an idea for a solution for these print head jams, I'm more than willing to listen. You can also contact me directly at curtiswright at charter dot net. Thanks in advance!

These scanners will collect alot of paper dust. You need to remove the ADF cover and using compress air and or a vaccum blow out the jam/original photosensor's, I believe there are 4 sensors. Power OFF then ON and try it..

SOURCE: Paper Jam
Open up the doors and blow some compressed air throughout the paper path (where the paper travels up). Make sure to blow air onto the sensors, because paper dust can coat them, causing false jams.
Does the paper get out of the tray at all? There is a feed roller that feeds the paper up into the machine; if you remove the paper tray you can see this roller -- it's big and gray and has grooves across it -- above where the paper sits toward the front of the printer. Blow air onto this roller as well, and if you have either D-ink or a rubber rejuvinator, clean the roller with a lint-free cloth.
Also make sure the paper is snug in the tray and not bent or crooked.
