RELIABILITY IN THE TRANSFER ROLLER

Two designs have been put in place in the predecessor models to improve the reliability

of the Transfer Roller. These designs are:

• New Materials in the Transfer Roller

• Transfer Voltage Monitoring System

The new transfer rollers contain smaller diameter forms that reduce the chances

of smudged printouts. The new materials also enable the roller to maintain the stability

of the printed images. This is a result of the roller's consistently low resistance and

high durability.

The transfer voltage monitoring system switches the electric current of the transfer roller

when the voltage reaches its limit. The voltage limit depends on the black-and-white

ratio, paper size and paper type, therefore the voltage limit will vary. This monitoring

system prevents edge smudges, image voids and poor transfers and as a result yields

superior image quality.

The reliability of the DF-502 has been achieved by maintaining the design

of the predecessor models:

• Reduced Skewing Ratio

• Keeping added Document Feeder Guide

The DF-502 Automatic Document Feeder's central standard paper pass enables

the paper to be transported more equally when compared with previously used one-sided

pass. The accuracy and stability of this transportation process is maintained regardless

of the paper size, paper thickness or paper type. As a result, it reduces the skewing ratio.

A document feeder guide added to the side guide of the previous generation made

it easier to set originals for copying. This change has been carried through to the

DF-502. This simplifies placing curled documents in the automatic document feeder

and eliminates paper jams caused by curled paper edges.
