The action of friction electromagnetic clutch in laser printer-Alice

November 27, 2021

The paper feeding devices of high-end printers of HP, Canon, Epson, etc. mostly use friction-type electromagnetic clutches to directly drive the pickup roller and paper alignment roller to feed paper. Its working principle is: when a current signal flows through the internal coil of the electromagnetic clutch to generate an electric field, the linkage fork in the middle of the clutch is pushed to one end of the coupling, and the two friction plates produce friction stop, and the pick-up wheel is driven by the shift fork to rotate and print The paper is fed into the front edge of the "paper registration roller" inside the printer and the printing paper is slightly bowed, and the printing paper is aligned with the registration roller. At this time, the registration roller does not rotate. When the registration roller clutch receives a command to rotate, it will feed the printing paper into the printing path (the pickup roller of the friction type electromagnetic clutch is circular rather than cam-shaped).
