8-3-4. 47 mode
47 mode is used to check the input and output. The operation of each electrical part can be confirmed. This mode
is also used to initialize the drum, developer and settings.
Operation example: To carry out the JAM2 sensor check (code 22).
: Indicates key operation.

Note 2: When the paper length is from 314mm to 347
mm, if the paper size set with the cassette
paper setting and the detected paper size
differ, an error code (P11, P12) will appear.
Note 3: When the paper size error code does not
appear, the detected paper size will be detected. (The cassette paper setting’s paper
size will be reset.)

8-5. Automatic paper size detection
When the automatic paper size detection is selected
with the user setting mode (C-61, 62), the paper
length will be automatically checked by JAM 1 sensor.
Note 1: The paper length is detected during the first
copy operation, so the 1st copy time will not
satisfy 12CPM.
(When feeding from lower cassette.)
