2-1-5 Cleaning section
The cleaning section consists of the following parts and removes the residual toner on the drum after transferring the
toner from the drum to the paper and collects it as a waste toner. The eraser light emission removes the residual
electrical charge on the drum surface.
The cleaning blade is always applied to the drum to scrape off the residual toner. The scraped toner is conveyed to the
cleaner screw by the sweep roller as a waste toner. The cleaner screw sends the waste toner to the waste toner
conveying belt that is attached to the outside of the frame drum. The waste toner conveying belt conveys the waste toner
to the waste toner reservoir that is provided by separating the inside of the toner container.
The drum that the residual toner is removed is irradiated by the eraser lamp (PWB) light attached to the upper part of the
process unit (the lower part of the laser scanner unit). The eraser lamp (PWB) consists of the LED array that
corresponds to the length of drum, and it is designed to remove the residual electrostatic charge on the drum surface by
irradiating the eraser light and then give the uniform charging on the drum by the main charger which is the next process.
