Les photocopieurs font preuve de bon sens

1. La valeur nominale de l’alimentation doit être sélectionnée de 200 V à 240 V, 50 Hz et au-dessus de 8 A
If the voltage is too high or too low, the copier will not work normally, and other equipment should not be on the same line as the copier. Use a three-phase socket for grounding.

2. Protégez soigneusement le matériel de bureau
Do not drop metal parts such as paper clips or pins into the machine, do not place heavy objects on the machine, and do not place containers filled with liquids on or around the copier.

3. Dans les situations suivantes, veuillez couper immédiatement l’alimentation et demander à un réparateur de réparer la machine
Fault codes appear, the machine has abnormal sounds and odors, the machine is wet by water or other liquids, and the machine casing is overheated.

4. L’utilisation de faux dommages au toner
The main component of toner is not composed of carbon, but most of it is composed of resin and binder. In the last process of copying and printing, the toner is melted into the paper fiber at a high temperature of 150°C to 200°C, and the resin It is oxidized into a gas with an odor, which is what we call ozone. Genuine toner does not contain carcinogens, and the "substitute powder" (that is, fake toner) we usually use is not much different in appearance, but the content is completely different.
False toner will also cause adverse effects on the copier, usually intensified background dust, uneven color depth, reduced number of copies of copy paper, increased wear and tear of the toner cartridge, reduced lifespan, easy toner on the fixing roller, the inside of the machine The dust falls on the circuit board, forming a short circuit and burning the equipment.

5. Comment choisir le papier à copier
When we purchase copy paper, we should focus on the appearance characteristics of the paper, such as the whiteness, thickness, uniformity, regularity of cutting and so on.

6. Endommagement du papier défectueux
Defective copy paper contains acid, which seriously corrodes the toner cartridge, wears the drum, and dust is adsorbed on the surface of the toner cartridge. The friction is large, causing serious wear and tear, the service life of the toner cartridge is reduced, the copy becomes black, the handwriting is blurred, the paper is jammed at the paper output part, and the print is uneven. , the interior of the copier becomes dirty and the dust increases.

7. Est-il préférable d’éteindre le copieur lorsqu’il n’est pas utilisé ou d’économiser de l’énergie ?
It is generally believed that the copier should be turned off after copying to save power, but frequent switching on and off will affect the life of some parts of the machine, and it will take a long time to wait for the machine to warm up again. If you use the automatic energy-saving function of the copier , not only can greatly shorten the warm-up time when copying again, but also reduce power consumption. Therefore, when the interval between two copies does not exceed 30 minutes, it is better to use the energy-saving function of the copier.

8. Gestion des bourrages papier
Paper jams account for 70% to 80% of copier failures. How to deal with paper jams correctly and effectively? Usually copiers have paper jam indicator lights on the panel. Find the corresponding part on the machine and take out the jammed paper. Do not pull it forcibly. Be careful not to scratch the photosensitive drum when handling the jammed paper.

9. Comment réduire efficacement le taux d’erreur de bourrage des copieurs
Choose neutral copy paper to prevent the copy paper from getting wet. Align the paper side by side, left, right, up and down.

10. Pourquoi le copieur devrait-il être régulièrement protégé ?
Copiers are different from ordinary machinery and equipment, and their principles are complex and involve common sense such as electronics, optics, chemistry, physics, and mechanics. After the copier is used for a period of time, due to the dirt and aging of the optical system, imaging system and fixing system, the copy becomes dirty and black with background gray, or even completely white. It is necessary to maintain it so that the copier can be used normally and reduce the failure rate.
