Why can't the inkjet printer print any characters?

This may be caused by the following circumstances:

1. The parameters set by the inkjet printer are incorrect. You need to reset the parameters according to the instructions in the user manual.

2. If the editing is incorrect or there are no edited characters, you need to clear the screen to edit again.

3. It may be that the position of photoelectric switch of Guangzhou inkjet printer is not properly adjusted, so it is necessary to adjust the position of photoelectric switch.

4. There is no high voltage on the high voltage board. This can be achieved by using an insulated screwdriver to try whether the high-voltage board is ignited and checking the intensity of ignition. Pressure and humidity are high, stop printing and debug later.

5. The single chip microcomputer board is disturbed by the external magnetic field, and the inkjet printer will be a strong magnetic field source, so it needs to be restarted and adjusted.

Extended data

Safe use of inkjet printer;

Fire protection. Most inkjet printers use ketone-based or alcohol-based inks, and most cleaning liquids used also contain ketones and alcohols. These chemical reagents are flammable and explosive, so you must pay attention to fire prevention when using them too heavily. Any used cleaning material, such as paper towels for wiping, is a fire hazard.

These materials must be recycled in time after use and disposed of in a safe way. Don't use water to put out fires caused by electrical appliances. If the fire caused by nitrocellulose ink must be put out with water, the power supply must be disconnected first.

Many inks contain nitrocellulose as a binder, so they are very flammable when dried and produce oxygen when burned, so it is best to put out the fire by cooling, such as using water.
