Printer general maintenance – How to clean the laser printer ?

1. Reduce external dust

What is the number one enemy of laser printers? Dust! Because the laser printer works by static electricity, it can strongly absorb dust. Any clean office is dusty, and the paper itself has tiny fibers similar to dust. These fibers, dust mixed together, and then after “hot” processing, will become a “universal” adsorption of dirt. In order to fix the toner, the last process of laser printing is heating by heating the roller. The “residual heat” of this process will make the dust accept the “firing” process and become a hard structure. We should pay attention to the ventilation of laser printer, but we can’t put it on the ventilation channel. If we put the printer on the vent, aisle, or next to the door and window, the printer with static electricity will play a role of “magnet” to absorb dust.

2. Hazards of internal dust

The printer is a technology complex. It will spread millions of toner particles precisely on a piece of paper. While doing this work, there will inevitably be a small amount of “litter”. When these small particles are mixed with the small fibers shaken off from the paper, they become the “micro” garbage with strong adsorption. Gently shaking the powder box to make the toner evenly distributed will help to achieve good printing results, but if you use excessive force to do this work, it may cause toner leakage, resulting in adverse consequences. Should pay attention to the use of clean paper, not only to ensure the printing effect, but also for internal cleaning.

3. Learn simple cleaning

Many faults of laser printer need to be repaired, the root cause of which is dust. It is very necessary to clean the printer regularly and effectively, but how do we do these daily cleaning work? The simplest and reliable way is to have professional maintenance engineers clean the printer regularly, but some cleaning work can be done by ourselves through careful operation. Too much dirt in the paper path will make the printed paper dirty. When cleaning the paper path, first open the cover of the printer, take out the selenium drum, and then gently wipe the roller and other relevant parts back and forth with a clean and soft wet cloth to remove paper scraps and dust. Because of the corona net technology, the ozone filter is installed on the laser printer. The ozone filter should be replaced at least once a year. After each replacement of the powder box, the corona net shall be cleaned with an alcohol swab. More often, use soft gauze to clean the carbon particles on the inner wall. Carefully clean all visible and accessible parts of the interior, just like cleaning camera lens. The best way is to use a small vacuum cleaner to absorb the powder particles without blowing the leather ball (do not directly wipe the smooth surface of the drum to avoid scratches). These cleaning work can reduce the black spots or stripes when printing.

4. Special cleaning tools

You can buy some special laser printer cleaning tools. Cleaning paper is a kind of special paper with the shape of ordinary paper. It has a strong adsorption effect. When it is used, it is put into the paper feed slot and have the laser printer print a blank file. The purpose is only to make the cleaning paper move normally. The cleaning paper is like a sponge to stick away the dust on the roller and paper path. Repeat the operation several times to complete the cleaning work on the paper track. For the dust adsorber, due to the influence of static electricity, carbon powder may be adsorbed to other parts of the printer. Replacing the powder box and pulling out the jammed paper will also cause the diffusion of carbon powder. These scattered carbon powder may fall back to the paper path, which is one of the reasons why the printed paper is not clean. The carbon dust adsorber itself is also charged with static electricity, and is made of elastic active adsorption materials, so it is easy to clean up the internal dust.
