The humidity sensor head uses a humidity sensitive capacitor Cs, which uses a moisture sensitive polymer film as a dielectric, and uses the film to adsorb the reversibility of water molecules, so that the change of the dielectric coefficient is reflected in the change in capacitance. The humidity sensitive capacitor has strong anti-interference ability and good linearity. IC1 and IC2 use a dual time base circuit 556, half of which is made into an astable multivibrator. The oscillation frequency is determined by R1, RPl, and Cl. The oscillation period of the illustrated parameters is about 130?s, and the duty ratio is 1: 1. IC2 and R3, the humidity sensitive sensing capacitor (Cs) form a one-shot delay circuit.
The Cleaning Blade is a kind of Printer Accessories.
The cartridge is irradiated by laser beam to adsorb toner, and then the toner is hot pressed by fixing roller for printing. In this process, there will be part of toner residual, which can not be "granules returned to the warehouse"; Automatic cleaning function is not adsorbed new toner particles and directly print, will remain toner away, fully ensure the next printing effect. And the Plate-Grid plays an important role. When high voltage generator to a high voltage electrode, wire electrode with reseau formed between a strong electric field, and release the corona, wire electrode and the photosensitive drum ionizes the air between the air ions migrate to the drum surface, make the photoconductor (drum) surface is full of charge, so can spare toner "adsorption to warehouse", so as to save toner, The purpose of reducing environmental pollution.
