Because the Brother cartridge is split, you need to install the toner cartridge and drum unit together in the printer before using the printer.

The first type of failure phenomenon is that after the power-on self-test, the paper is fed in and can suck in the paper, but the print head moves and then exits the paper.
Let's first analyze the cause of the failure. The photocell on the print head must measure the left edge of the print head and the left border of the paper to determine the starting position of the print. Therefore, when the paper is inhaled, the print head moves and the paper is detected by the photocell on the print head boundary. The fault is that the photocell can find the left edge of the print head, but the left border of the paper cannot be found and the paper is ejected.
After finding the method, how to repair it?
First, the photoelectric parameters change, and the photoelectric parameters need to be reset. The second step is to remove the photocell and clean the photocell. Finally, the photocell is damaged or aged, and the photocell is replaced.

The first step in repair is to remove the print head, check if the print head is missing, and change the needle if it is missing. The second step is to check if the print head cable is plugged in and the print head cable is broken. Finally check the main board pin drive circuit, the main fuselage F23, F27, F28 (3.15A250V) three fuses respectively play the role of 8 pin drive circuit protection, if there are 8 pins, first check F23, F27, F28, if only If one or two needles are missing, the corresponding drive tube and drive circuit of the needle should be checked.
