Problems picking up paper


You should get it checked by an Authorized Service Professional. If this doesn't do, check if your paper is of a compatible weight (GSM) Check your Machine for compatible paper specification and to know this you may read user manual or your machine. Then check your Paper Packet. If your paper is of a compatible weight, you should call authorized service engineer of your machine. If you find you were trying with a non-compatible type of paper, change to a compatible paper and if it still jams, something wrong with your machine is definite. Contact Authorized Service engineer in such a case.

Machine diplays "paper jammed" with no paper in


Hello
This the method to clear paper jam, follow these steps:-
Turn the printer off and on to see if it can automatically clear some or all of the jam. Many printers provide an error-code listing on the front panel display for the area where the jam occurred. If your printer shows an error code, be sure and check the printer manual to see if that identifies the area of the printer where the jam occurred.
Turn off the printer.
Remove any paper trays. Inspect them for wrinkled or damaged paper.
Open any other doors that give access to the printer's paper path and to the ink cartridge. 5 If necessary, remove the ink cartridge. Place it in a bag or away from light to avoid damaging it.
If you find a piece of jammed paper, remove it by holding it with both hands and pulling firmly. The goal is to keep the paper from tearing. If several pieces are jammed together, try pulling out the middle piece first to loosen the jam.
If the paper does tear, try rotating the roller gears manually to free the paper. Don't force anything, though.
Replace the ink cartridge and paper trays, close any doors you opened and turn the printer back on.
If the printer paper jam message still appears, then there is still some paper in the printer. Reinspect the paper path.
Good Luck

Paper jam


  1. Turn off the printer.
  2. Remove any paper trays. Inspect them for wrinkled or damaged paper.
  3. Also open the back cover of the printer if this model has one.
  4. Open any other doors that give access to the printer's paper path and to the toner or ink cartridge.
  5. If necessary, remove the toner or ink cartridge. Place it away from light/ sun light to avoid damaging it.
  6. If you find a piece of jammed paper, remove it by holding it with both hands and pulling firmly. The goal is to keep the paper from tearing. If several pieces are jammed together, try pulling out the middle piece first to loosen the jam.
  7. If the paper does tear, try rotating the roller gears manually to free the paper. Don't force anything, though. Do this step especially if the jam message comes up repeatedly without any obvious paper jam, there may be a small tear of paper inside.
  8. Ones the printer is free of paper Replace the toner or ink cartridge and paper trays, close any doors you opened and turn the printer back on.
  9. If the printer paper jam message still appears, then there is still some paper in the printer. Reinspect the paper path.
