The registration roller clock sensor (PI5) is used to measure the length of originals with reference to the revolutions made by the clock plate mounted to the slave
roller of the registration roller. Based on the revolutions of the lock plate, the ADF controller PCB identifies the length of the original in question (in feeding direc-
tion).

The DADF uses the data on the width and the length of the original obtained by original detection 2 to identify a default size, and sends the result to the copier. In
response, the copier selects the appropriate copy paper size to suit the identified size of the original.
