THE PAPER ADVANCE ROLLER DOES NOT ROTATE. THE PLASTIC GEAR ON THE ROLLER ROTATES WHEN THE LID IS CLOSED AND THE PAGE ADVANCE IS PRESSED. THE ECG PAPER DOES NOT ADVANCE. WHEN I OPEN THE LID, I CAN ROTATE THE PLASIC GEAR ATTACHED TO THE PAPER ADVANCE ROLLER AND THE ROLLER. WHEN I TRY TO HOLD THE PLASTIC GEAR ATTACHED TO THE PAPER ADVANCE ROLLER, I CAN ROTATE THE ROLLER INDEPENDENT OF THE PLASTIC GEAR. I NEED TO USE MODERATE FORCE TO MOVE THE PAPER ADVANCE ROLLER INDEPENDENTLY OF ITS ATTACHED PLASTIC GEAR. WHAT IS THE SOLUTION?

I have the same model (Schiller AT-102) and unfortunately the same problem. I've tried almost everything with the hope of solving the problem: I changed the tightening springs which push the printer thermomatrix to the roller. Also replaced the optosensor. And so on... But nothing changed the situation. I would ask you to tell if you already have found the cause and the cure. Thank you in advance!
Get the toner cartridge out from the printer, move the plastic cover so you can se the light green roller. On both ends of the roller are gear wheels, use your fingers to rotate them and see if there is any toner on the green roller (lines). Check if there is some piece of paper or some dust or dirt on the roller, and if there is, gently wipe it with the dry soft cloth. If the problem persist, try changing the toner cartridge.
1. Switch on the recorder
2. Pull up the handle of the paper door and fold it out
3. Remove the cardboard from the top of the new pad and place the pad, including the cardboard backing at the bottom and with the arrow pointing towards the unit, into the paper compartment
4. Pull the top sheet out of the compartment and guide it around the guide roller
5. Holding the leading edge of the paper in place between the two markers on the recorder, close the paper door. Ensure that it locks into place on both sides.
- When inserting an already started Z-fold pad, the grid side must face up and the first fold must point the compartment.
(You can find more information at MAC 1200 Operator's Manual, there page 59.)
change the IOT back side clutch that appear behind the back side of machine which rotates the ITO (black roller in main path of paper) just try with cleaing clutch other wise change it
and remove that IOT back side gear which rotate IOT black roller without that gear u can print
Try these steps.
Print transfer jams
1. If a piece of paper is trapped in the paper preheater, try pushing out the paper by
inserting a stiff piece of cardstock into the paper preheater.
2. Using diagnostics, test the paper preheater sensors. If the test fails, replace the
paper/drum heater assembly.
3. Check to see if the upper feed roller drive belt is broken or slipped off of its pulleys. In
such a case, the upper feed roller does not rotate when the lower feed roller rotates.
4. Check that the feed rollers rotate smoothly and that the front cover is fully closed and
5. Check the paper-eject path for obstructions. Ensure no small pieces of paper are
trapped around the stripper fingers or rapid release guide.
6. Ensure that the transfix roller rotates during the transfix process. See SF168 and
7. Test the sensors in the paper path. Look for damaged or non-operating sensor flags.
8. Check the transfix solenoid and its cam. Ensure they operate correctly and are properly
lubricated. If lubrication is needed, apply a dab of grease to the contact point between
the cam and the latch and the cam and the cam-advanced spring. Refer to
"Lubrication" on page 6-177.
9. A stripper finger, or rapid release guide, jam can occur because of broken teeth on the
small section of the back-side of the compound gear. The root cause of this may be also
be due to a lack of transfix cam grease. If you find broken teeth on the compound gear,
check for proper lubrication of the transfix cam. Be careful to ensure that no grease
touches the Y-axis belts. If the belts get contaminated with grease they must be
replaced. wipe off any excess grease to prevent it from dripping onto the belts.
open the toner access door remove the toner, slowly lower the tone access door and ensure that the top roller (charge roller) is lowering straight. the roller in the bottom of the cavity (the transfer roller) push down on this to ensure that it has spring tension. if the top one is level and the bottom one has tension then you'll need to change the high voltage power supply.
Ok this issue ussually occurs when the roller feed doesn't load the paper due to the following reasons:
1. If your printer is operating for more than two years or so... gear tear will most likely to occur. If you can open the printer and check everytime the printer initiates after power on ad if the roller feed doesn't rotate but the leftmost rotary gear with the encoder wheel rotates, the gear is most likely to be loose even there is no paper jam nor dust contamination on the rubber and paper feed mechanism. You need to replace the said gear with the encoder strip . A simple solution would be aplying epoxy resin so it will be fixed on the rotary shaft. It may last for quite sometime but better yet replace the gear.
2. The feeder rollers might be dirty and needs to be cleaned and greased the gears.
3. Probable defective print cartridge. Try replacing it with a new one.
But based on the items above, if your printer is operating more than a year or two, and frequent paper jam is being experienced, gear tear near the motor is the culprit.
First – diagnose your problem. In my case the first roller
which feeds the paper through the ADF (under small black flip up cover on top)
was not turning. Hence no paper advance and error claimed a paper jam (it wasn’t
– just a failure to advance paper)
The cause turned out to be a stuck gear turning that silver
rod at the top. A bit of household oil has worked a charm.
To get at the gear, unhinge the ADF cover retaining tie
(black flexible plastic stopping it opening all the way). Just lift it up and
roll over towards printer.
Then unscrew one screw next to that tie. Gently prise
plastic cover off by lifting up from left hand side (near that black tie). It
should rotate off. Keep power on and fingers out.
Put a few drops of oil on top gear. Place paper in ADF and
attempt a batch scan operation. Gears should turn and lubricate parts. Repeat. Once working, replace cover, screw and tie.
Mine had seized months ago and is now working fine. Hope
yours does too.
