Paper Delivery

Mainframe

The paper feed/delivery system consists of various technologies to meet high front-to-back registration

requirements demanded in the commercial printing market. The paper fed from the tray is first checked

for double-feed and is then adjusted of skew and main/sub scan registration before the belt-to-paper

transfer process.

Skew detection & main scan registration

A Ricoh original technology is applied to separately control skew correction and main scan registration,

to achieve high accuracy in front-to-back registration.

1. CIS

measures the amount of skew.

2. The registration roller rotates (about the fixed support axis) and then shifts sideways to adjust the

skew and main scan registration.

• 1. Contact Image Sensor (CIS)

CIS calculates the amount of correction

• 2. Registration roller

The registration roller adjusts the skew and main scan registration.

Leading edge detection mechanism in more detail

When the paper passes through the registration roller, the CIS emits light and reads the amount of

light reflected, to detect the leading edge.
