When using the printer, we often encounter a problem is a sudden jam, so why suddenly a paper jam? The following will analyze several major reasons.

1, separation claw wear
The long-term use of the copier, the machine drum or fuser roller separation claws will be severely worn, resulting in a paper jam. When it is serious, the separation claw can not separate the copy paper from the drum or the fixing roller, causing the paper to jam on it. At this point, the application of anhydrous alcohol cleaning fuser roller and separation claw on the canon CF510A toner, remove the blunt separation claws, with fine sandpaper grinding sharp, so that the copier can continue to use for some time. If can not put the printer toner out, only replace the new separation claws.
2, paper path sensor failure
Paper path sensor is located in the separation area, the fuser port, etc., the use of ultrasonic or optoelectronic components of the paper through the detection or not, such as sensor failure can not detect the passage of paper. When the paper is in progress, when the sensor touches the small lever of the transport, it blocks the ultrasonic wave or light, thus detecting that the paper has passed and issued an instruction to proceed to the next step. If the small lever turns off, it will prevent the paper from advancing, causing a paper jam. Therefore, check whether the paper path sensor is operating correctly.
3, the alignment roller wear and drive the clutch damage
The registration roller is the copier paper, and the hard rubber roller, which drives the paper forward, is located on the upper and lower sides of the paper. Aligning the roller will slow the paper forward, the paper will often stuck in the middle of the paper path. Damage to the registration roller The clutch can not be rotated and the paper can not pass through. If this occurs, replace the new registration roller or do the appropriate treatment.
4, export baffle displacement
The copy paper is output through the exit baffle, and a copy process is completed. Long-term use of the hp toner cartridge, the exit baffle sometimes displacement or deflection, to prevent the smooth output of copy paper, resulting in paper jam failure. At this time should be adjusted on the exit baffle, so that the baffle straight, free movement, jam failure will be resolved.
