OKI (1881, Japan, Japan's earliest manufacturer of electronic communication products, top ten printer brands, OKI Industrial Co., Ltd.) Extended information: Internal cleaning of the printer. Since the internal parts of the printer are relatively delicate, even ordinary wiping or lubricating oil may have an immeasurable impact on the print quality, so internal cleaning must be done carefully. Based on my experience, the parts that can be cleaned are listed below for your reference. Toner Protectors Printer cartridges all have pads that absorb excess toner from the roller system that transports the paper. Users can remove it from the machine and clean it manually. Usually, new liners are included with new cartridges. Paper feed rollers are the conveying parts of the printer, dragging the paper from the paper slot to the inside of the printer. However, during this process, oil and dust from the paper will also be deposited on the rollers. If it is not cleaned for a long time, it will cause paper jams and paper feeding errors, which are also the most common printer failures. Coronal dust deposits can affect the efficiency of electrostatics (especially for some older laser printers).

The air vents are similar to those inside a computer. Many laser printers also have internal fans, which will be blocked by dust and dirt when working all year round. We must ensure that the vents and fan blades are cleaned regularly to maintain air circulation inside the printer. Depending on the way a line of words is formed on paper, there are serial printers and line printers. Depending on the technology employed, there are cylindrical, spherical, inkjet, thermal, laser, electrostatic, magnetic and LED printers.
