Up for sale is a genuine OEM HP Laser Scanner Assembly Unit, cleanly pulled from a working HP Color LaserJet Pro MFP M476dn printer. This unit has been fully inspected and is guaranteed to be in 100% operational condition.
If your printer is flashing a 51.XX Error (such as 51.20, 51.21, 51.22, or 51.23 laser scanner errors), or if you are getting entirely blank or severely distorted prints due to laser polygon mirror or beam faults, replacing this laser block assembly will resolve the issue.
