When there are some simple faults in the printer, we can also detect and repair it ourselves, which can save a lot of time.
One of the maintenance methods: the inkjet printer can't print clearly. Due to the long-term use of the printer, the handwriting may be unclear and intermittent. One of the reasons may be that the ink cartridge is out of ink. In fact, at this time, the printer will also have a corresponding prompt, and the ink itself needs to be replaced, especially the four-color ink cartridge, which is often the most used, so pay special attention when using it, and add it in time when there is not much ink; Another reason is that there are bubbles in the ink cartridge, which makes the blocked letters unable to release ink. In view of this situation, we need to take out the ink cartridge, use a straw to drive away the air, and then test printing several times before the printer can resume normal printing.
The second maintenance method: one of the reasons why the nozzle of inkjet printing is blocked is that the printer is not used for a long time, the ink dries up, the nozzle is blocked, and normal printing cannot be carried out; Therefore, we also need to ensure that the printer is used once a week for further study, so as to keep the nozzle in a smooth state. Otherwise, the nozzle needs to be replaced after it is blocked due to long-term non-use.
The third maintenance method: laser printer paper jam
Although there are many reasons for the paper jam in laser printers, the solutions are basically the same. After the paper jam occurs, we need to slowly pull out the stuck paper according to the paper feeding direction, so as to avoid scratching the surface of the photosensitive drum and effectively avoid the paper scraps from staying in the printer. If the paper jam is deep, we need to open the back cover of the printer to take it out slowly.
