Registration Transport
The paper from the bank/LCIT (option)/duplex transport section is transported to the registration section through the relay transport section.
The paper from the bypass feed section is transported to the registration section through the bypass relay transport section. The bypass relay transport section is located in the registration unit.
When the registration sensor [A] detects the leading edge of the paper, the relay motor starts to slow down.
After the leading edge of the paper hits the registration rollers [B] [C] for the skew correction, the relay motor stops. Then the registration motor [D] starts to drive the registration rollers [B] [C], to feed the paper into the machine. (For details about the adjustment of the paper buckle, see "Skew Correction" in this section. For details about the adjustment of the transport timing, see "Leading Edge Registration" in this section.)
The registration mechanism is driven by a single motor [D], so this machine does not have a registration clutch. This prevents shock-jitter which occurs when a registration clutch turns ON.
When a paper jam occurs, lever [E] separates the upper registration roller (idle) [C] from the lower registration roller (drive) [B] to let the user easily remove the jammed paper.
Skew Correction
The leading edge of the paper is made to hit the registration rollers and the paper buckles in order to be aligned for the skew correction.
If the paper buckle is too small, the whole width of the paper leading edge does not hit the registration rollers. Then the paper skew is not corrected completely. The paper buckle can be adjusted with SP1-004-001 to 012.

For details about the skew adjustment, see Adjustment 005: Registration.
Leading Edge Registration
The leading edge registration is made by adjusting the paper transport timing of the registration rollers. This registration method is same as that of MP C6000/C7000.
The registration rollers stop the paper and adjust the timing for feeding the paper into the machine order to match the positions of the paper and the image on the transfer belt. The leading edge registration can be adjusted by SP1-001-001 to 016 (Lead Edge Reg). For details, see Adjustment 005: Registration.
Paper Dust Collection
The dust collection sheet [A] is attached to the upper registration roller (idle) [B]. The dust collection sheet [A] stays in contact with the upper registration roller (idle) all the time. This decreases the amount of paper dust that falls into the machine.
