Having a printer repaired by a service company can be a pretty expensive proposition so we’ve compiled a checklist below that may assist you in fixing it yourself.
Over a period of time the rollers wear down and become slick and don’t pull the paper in fast enough. If the paper is stopping in the fuser section it might be a bad gear or some debris causing the jam.
Most image problems are caused by a bad toner cartridge. If you have any streaking, light/dark areas or repetitive spots on your print, replace the cartridge and see if it clears up.
This is common when using poorly remanufactured cartridges. Some recyclers don’t replace the image drum and they should because the original drums are only designed to last for the expected toner life.
If problems persist after replacing the cartridge the next area to look at would be the fuser. The heat rollers can become torn or warped after a period of time causing an image defect.
