Because the print head is not sealed tightly after normal printing or is left for a long time, the water evaporates excessively, causing the ink particles to dry on the fine tip of the print head, making the ink unable to spray normally; or different inks are mixed with each other, resulting in chemical reactions, […]
The OPC（Organic Photoconductor）is the photosensitive drum, which is the core component of the laser printer. It is generally not sticky with toner. If there is toner on the drum core, it should be cleaned in time. The possible reasons why the drum core is sticky with toner are: 1. There are sticky substances such as […]
Toner powder are not universal. The universality of toner powder depends on multiple factors, including electrical properties, magnetism, etc. Specifically： Electrical properties: The electrical properties of toner powder must be consistent. Magnetic properties: Magnetic powder can barely replace non-magnetic powder, but non-magnetic powder can never replace magnetic powder.
1. Clean the toner cartridge chip If the printer does not correctly detect the toner cartridge, it will prompt "Consumables remaining error". You can remove the toner cartridge and use a clean cotton swab or paper towel to clean the toner cartridge chip 2. Reinstall the toner cartridgeIf the toner cartridge is not installed in […]
1. Vertical black lines of more than 1 cm in width appear on both the printed document and the drum core: This is a problem with the scraper, which causes the powder on the stick core to not be scraped cleanly. 2. Vertical thin black lines appear on the printed document: Usually the scraper and […]
From the cost point of view, the cost of adding toner to the toner cartridge is much lower than that of replacing the toner cartridge, so adding toner is more cost-effective. However, from the actual use, since the toner cartridge is a sealed disposable consumable, adding toner by yourself will destroy the sealing performance of […]
1. First turn off the printer power switch, unplug the printer from the power outlet. 2. Then open the flip cover of the laser printer, carefully remove the photoconductor assembly, wipe its surface with a degreasing cotton, but can not force, in order to prevent the surface of the photoconductor scratched. 3. Next, wipe the […]
1. Do not place heavy objects on the copier. 2. Be careful not to let paper scraps, staples or other small metal objects fall into the copier. 3. Do not try to remove any fixed plates or covers while the copier is running, and do not turn off the power switch. 4. When making large […]
1. High density. The minimum printing resolution of laser printers is 300dpi, and there are also high resolutions such as 400dpi, 600dpi, 800dpi, 1200dpi, 2400dpi and 4800dpi. 2. High speed. The minimum printing speed of laser printers is 4ppm, generally 12ppm, 16ppm, and some laser printers can reach a printing speed of more than 24ppm. […]
1. When removing the "paper jam", only move the parts that are allowed to move in the copier manual. 2. Take out the whole paper at once as much as possible, and be careful not to leave broken pieces of paper in the machine. 3. Do not touch the photosensitive drum to avoid scratching the […]
