1, poor wire contact of transfer electrode; Reconnect.

2. The transfer electrode wire is disconnected; Replace the electrode wire.

3. The transfer electrode high-voltage generator is damaged or the high-voltage line has poor contact; Repair and replace the high-voltage generator or reconnect the high-voltage line.

Treatment method:

(1) The input voltage is too low. Adjust the voltage to meet the requirements;

(2) The high-voltage generator is burnt out. Replace the high voltage generator;

(3) Incoming and outgoing lines are not firmly contacted; Insert the contact firmly;

(4) Incorrect contact insertion. Insert the contacts correctly.

Second, the second piece of paper is not in good supply.

1, first observe whether the first step of paper rubbing is in place, if not, first solve the problem of paper feeding in place in the first step;

2. There is no image on the photosensitive drum.

Treatment method:

(1) Poor contact of the charging electrode or open circuit of the electrode wire; Reconnect the charging electrode or replace the electrode wire.

(2) The charging electrode high-voltage generator is damaged or the high-voltage line has poor contact; Repair and replace the charging high voltage generator or reconnect the high voltage line.

(3) Control the aging or damage of the clutch of the developer; Replace the clutch.

(4) The developer is misplaced or the driving gear is damaged; Reinstall in place or replace the driving gear.

(5) The photosensitive drum is not installed correctly; Reinstall.

Troubleshooting the printer:

Fault phenomenon: the printer does not receive the invoice.

First, the reason for the failure:

1, whether the surface of printing paper is flat or not.

If the stylus printer does not feed paper, first check whether the paper is flat and jammed. If the paper is stuck and crumpled, please try to replace it. Because the stylus printer requires the printed paper to be flat and smooth.

2. Check whether the printing paper is too thin or too much.

Generally, printing paper cannot exceed 60g. If it is too thick, it can't be fed, but it can't be as thin as sandpaper, so it will rot if it doesn't go in. Moreover, if the paper is too thin, it will lead to paper jam, which will not print, and will seriously damage the printer.

3. Check whether the pickup roller is worn.

The pick-up roller is a very important part of the stylus printer, and it is also the most easily damaged place. When the stylus printer can't take paper, print or feed paper, it means that this part is broken. Besides new ones, you can also wrap them with rubber bands for a period of time.

Second, the solution:

1, reduce the amount of paper used, and remove crumpled paper and paper that is too thin and too thick. Re-insert paper with moderate thickness and smooth surface.

2. Clean up the foreign matter blocking the paper inlet. If there is paper jam, please carefully take out the paper stuck in the paper inlet. Just put the paper back in and print it.

3. If the printing paper is wet, it should be replaced in time, and it is not allowed to print with wet printing paper.

You can't print when the ink is used up. Just change ink in time.

5, adjust the paper direction, find the most suitable position, generally because of the wrong position can not enter the paper.
