If your printer only prints black pages it will require the high voltage power supply to be replaced. this will fix your problem

go to the printer and faxes right click the printer and go to properties and click on the tes page

you have the wrong drivers for the printer. You maybe getting weird characters also. When you turn it off it clears the memory buffer (print job). I assume it seft tet OK. Delete and reload drivers

try deleting the printer and drivers completely, then reinstall

verify paper tray is set for correct paper. print the configuration menu and check the paper size for tray 1. If it does not have right size, examine the tray bottom to see if slider is in place

Check you Page Setup andmargin set. Sounds like the page isn't set up properly. When you typing a document, go to the FILE then PAGE SETUP. Margins and Paper Layout.
Hope this helps. Bud

Your paper size settings for Tray 1 is probably wrong. Make sure it is set to Letter and the type is Plain Paper. If your Paper size is Universal, then either the paper guide in the tray is set wrong or the paper size sensor is broken. If the sensor is broken, you can disable auto paper size sensing so the printer will allow you to specify a paper size. To disable paper size sensing, you need to go into Config Mode. The other way is to send a PJL command to the printer to disable the function.

What happens is that the rubber roller that's supposed to pick paper up and load it in doesn't pull the paper from the tray anymore, hence it gives the paper jam error message. If you want you can replace that rubber roller to fix the problem, however first thing I do is to take that rubber roller out (remove tray and look underneath to find the roller) and turn it inside out then fit it back. This will give the rubber roller the grip that it missed and solve your problem.

It sounds like you are describing the pick arm or autocompensator. It also sounds like you have the printer turned on its right side for that to be on the left. The part you are looking for is part # 99A1056 for the Optra T610.
