As shown in the figure, the gain programmable isolating amplifier circuit. The circuit combines the isolation performance of the isolation amplifier ISO122 with the programmable gain control of the PGA102. It also uses the isolation function of the bidirectional digital coupler ISO150 to isolate the input/output signal isolation and gain control signals. Figure (b) is an internal block diagram of ISO122.
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.
