Laser Scanner For HP LJ P1007 | Canon LBP3108 (REFURBISHED)

The Refurbished Laser Scanner Unit (LSU) (also known as the lower scanner or imaging unit) for the HP LaserJet P1007 and Canon Laser Shot LBP3108 is the internal electro-optical module responsible for drafting text and graphics before printing. It receives digital files from the motherboard and fires a precision laser beam onto a fast-spinning polygon mirror, reflecting the light down to draw an invisible static electrostatic blueprint across the OPC drum cartridge to attract toner powder.
