The HP Color LaserJet Enterprise CP4020/CP4520 Series Printer and CM4540 MFP use an
intermediate transfer belt (ITB). What is one difference between ITB technology and electrostatic
transfer belt (ETB) technology?

A.
An ETB uses primary transfer rollers to transfer the image from each OPC (image drum) to the
ETB; an ITB transfers the image directly to the media.

B.
ITB technology runs media along the length of the ITB during image transfer; ETB technology uses
a secondary transfer roller at the edge of the ETB during image transfer.

C.
An ITB uses primary transfer rollers to transfer the image from each OPC (image drum) to the ITB;
an ETB transfers the image directly to the media.

D.
ITB technology uses a cleaning blade and toner collection unit for ITB belt cleaning; ETB
technology uses only a residual toner feed unit for ETB belt cleaning.

Explanation:

The image transfer belt is responsible for transferring the latent image to the media. This is similar to
how an offset blanket works on a offset lithographic press. The advantage is with this design it is
possible to run thick stocks without the concern the stock will jam in the engine.
