CE863-40001 - HP Scanner Unit Assembly for LaserJet Pro 400 M475

Product Description

The CE863-40001 is the complete scanner assembly for the HP LaserJet Pro 400 M475 multifunction printer. This unit houses the optical sensor (CCD or CIS), the light source, and the motor mechanism that moves the sensor across the document or moves the document past the sensor. It is responsible for converting the physical image of a document into digital data that can be processed by the printer's firmware for functions such as copying, scanning to email, or scanning to a network folder. This assembly is engineered by HP to deliver consistent and accurate scanning performance, capturing fine details and accurate color reproduction where applicable. It is designed to integrate seamlessly with the printer's Automatic Document Feeder (ADF) or the flatbed glass, depending on the scanning method. The quality of the scanner unit directly impacts the clarity and fidelity of scanned documents and images, making it a critical component for any multifunction device. As a direct replacement part, the CE863-40001 ensures that the scanner's performance can be restored to its original specifications. Issues such as streaks, faded images, or complete scanning failures often indicate a problem with the scanner unit. Installing a genuine HP replacement part guarantees compatibility and maintains the expected level of performance and reliability for the LaserJet Pro 400 M475.
