ITB unit, Itb | HP Enterprise CP5525 specification

ITB unit

The ITB unit receives the toner image from the photosensitive drums and transfers the complete toner image to the print media. The ITB unit consists of the following components:

●ITB

●ITB drive roller

●Primary transfer rollers

●ITB cleaner

The ITB motor drives the ITB drive roller which rotates the ITB. The rotation of the ITB causes the primary transfer rollers to rotate. The ITB cleaner cleans the ITB surface.
