Drum Unit Spare Parts Kit 1pcs*( Drum Chip + CR+ PCR+

Original consumables, general consumables, compatible consumables; Domestic and imported; Domestic products include Lenovo, Gezhige, Xinge, etc; Generally, the original printing quality is the best, and the cost performance of domestic products is high, and the quality is also good. Some can be compared with the original. Types: toner cartridge, ink cartridge, toner, ribbon, etc. Each printer belongs to its owner according to the type of printer.
By printer type, printer consumables can be roughly classified as follows:
Printer ribbon
Needle printer, ribbon. Needle printer ribbon, divided into broadband and narrowband. Some ribbons can be replaced separately, and some ribbons must be replaced together with the ribbon holder. The ribbon of different colors can be replaced as required;
Laser printer, toner, toner cartridge. The toner and toner cartridge of some laser printers can be separated. After the toner is used up, it can be easily filled with toner, and then continue to use until the toner cartridge is aged and replaced; Some laser printer toner and toner cartridge are integrated. After toner is used up, the toner cartridge will be discarded, causing a certain waste. The cost of the selenium drum accounts for a large proportion of the total cost.
Printer Toner
Ink jet printer, ink, integrated ink cartridge. The inkjet printer has four colors, five colors, or six colors depending on the printing color. Generally, the printer ink can be replaced with one color ink independently, rather than the earlier inkjet printers. As long as one color ink is used up, it must be replaced together with the remaining colors, causing waste. When the ink of some printers is used up, as long as the ink is replaced, the print head can be used permanently. The advantages of this printer are that the cost of replacing ink is low. The disadvantages are that if the print head is used for many times, the print quality will decline, and the problem of clogging the nozzle is easy to occur. In serious cases, the printer needs to be repaired or scrapped; Some printer nozzles and ink cartridges are integrated. When the ink cartridge is replaced, the nozzle at the bottom of the ink cartridge is also replaced. This kind of ink cartridge is expensive. The advantage is that this type of printer will not have the problem of nozzle blockage. If it is blocked, the printer can still be used after the ink cartridge is replaced, and the print quality can be kept beautiful.
Relatively speaking, the use cost of ribbon is the cheapest, and the disadvantage is that the printing effect is not ideal, and color images and texts cannot be printed; Laser printer toner and toner cartridge are the most expensive and have the highest printing accuracy, but the color effect is not as good as inkjet printer; The ink and ink cartridge of the ink-jet printer are of moderate use cost. The color effect of printing is the best and the printing accuracy is high. However, the ink-jet color is generally less durable than the laser. It is easy to fade and become damp after a long time.
Internal cleaning
Because the internal parts of the printer are relatively precise, even ordinary wiping or adding lubricating oil may have an inestimable impact on the print quality, so the internal cleaning must be careful. According to my experience, the following parts that can be cleaned are listed for reference.
Toner Protector
The ink cartridge of the printer will have some pads, which are used to absorb the excess toner in the roller system of paper transmission. Users can take it out of the machine and clean it manually. Generally, a new gasket will be included in the new ink cartridge.
Paper feeding roller
They are the transmission part of the printer. They drag the paper from the paper slot to the inside of the printer. However, during this process, the oil and dust stained on the paper will also settle on the roller. If they are not cleaned for a long time, paper jams and paper feeding errors will occur, which is also the most likely failure of the printer. Here, we can wash these deposits with cotton wads soaked in alcohol or wet cloth. In addition, there are special roller cleaners in some office equipment professional supplies stores.
Coronary wire
The precipitation of dust will affect the use efficiency of static electricity (especially for some old-fashioned laser printers).
Vents
Like the inside of a computer, many laser printers also have internal fans, which can clog the perennial work with dust and dirt. We must ensure that the vents and fan blades are cleaned regularly to keep the air flowing inside the printer.
The above are the components that can be cleaned inside the laser printer, but we must pay attention to that: because the laser printer uses the high heat method to adsorb the toner onto the paper. So remember to clean the printer just after completing the printer task, and pay attention to all parts with temperature warning signs. In some office supplies stores, we can also see some special laser printer "cleaning paper" for sale. Their surfaces are covered with special paper, which can absorb dust and excess toner in the printer's paper path. At the same time, because they will go through a complete printing process, the internal cleaning of the printer is also the most thorough.
