100 MFP unit explanation ENWW

*7 ADU pre-registration mechanism

In the ADU, paper is looped by the ADU

pre-registration roller to correct paper

inclination in the conveyance section. The

ADU pre-registration roller stops when the

loop roller motor (M6) stops; however, the

ADU conveyance roller continues to feed

paper at a constant speed, forming a paper

loop between the ADU pre-registration roller

and ADU conveyance roller. As a result,

paper inclination is corrected. When M6

starts, the ADU pre-registration roller starts

rotating to feed the paper to the second feed

section. An ADU conveyance MC (MC13) is

provided to turn on/off the drive force of ADU

conveyance rollers 1 and 2 in order to stop

the looped paper temporarily and to adjust

the loop size. In addition, an ADU

deceleration MC (MC2) is provided to turn

on/off the drive force of ADU conveyance

rollers 3 and 4. The ADU conveyance MC

(MC13) is turned on/off only when the paper

length is 325 mm or longer. If the paper

length is less than 325 mm, it stays on

during copying.

*8 Thick paper conveyance mechanism

copying, the conveyance motor (M5),

paper exit motor (M7), reverse/exit

motor (M8), and ADU reverse motor
