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.
