8.6.6 Identifying the Size of Paper (right/left deck)

iR5065 / iR 5055 / iR5075 / iR5075N / iR5065N / iR5055N

The right/left deck does not possess a mechanism to detect the size of paper, and the machine finds out the size of paper as follows:

(A4, B5, LTR)

[1] The position of the paper size guide plate of the cassette is changed.

[2] A paper size is registered in service mode.

SERVICE MODE:

COPIER> OPTION> CST> P-SZ-C1

Use it to specify a paper size for the right deck.
