High Capacity Feeder (HCF)
Paper Feed and Separation Mechanism
The high capacity feeder consists of a tray and paper transfer
mechanisms. The paper feed and separation mechanism uses a
friction roller separation and paper feed system with a non-contact
magnet type maintenance-free torque limiter.
When the paper feed clutch turns on, the paper feed roller shaft
rotates and the paper feed roller is driven with the one-way clutch.
The call roller rotates with the relay gears to feed the top paper. The
reverse roller rotates along with the paper feed roller.
During paper feed, if two sheets feed, the reverse roller rotates by
the torque limiter, returning the lower sheet. When the paper feed
sensor (reflection type sensor) detects the paper, the pickup
solenoid turns off to raise the call roller, transferring the paper to the
registration roller.
