There are many problems with the printer paper jam. For example, there are sundries in the paper outlet path, the rotation failure of the paper feed roller and other components, the paper box does not feed paper, and the sensor fails. The way to solve this problem is simple, just open the cover and take out the paper jam. However, it should be noted that the paper must be taken in the paper feeding direction, and any knob must not be turned in the opposite direction.

In addition, improper installation of paper tray and poor paper quality (too thin, too thick and wet) can also cause paper jam or inability to take paper. First, connect the printer to the computer, turn on the power, and the computer will prompt you to find the hardware and the driver according to the prompts. At this point, put the printer driver CD into the CD-ROM drive and install it according to the prompts.
