Table Key
The paper size switch consists of 5 feelers that slide along the wiring patterns
of the paper width switch terminal plate when the side fences are manually
1, 2, 3, 4,
adjusted to fit the size of the paper loaded in the tray. The H, L status of each
and 5
feeler is determined by whether the feeler is in contact with the wire of a
pattern.
H High (5 V) (Inactive)
L Low (0 V) (Active)
The machine determines the paper size automatically by reading the output of
the paper size switches and the paper length sensor.
The machine cannot detect the paper size automatically. The user must select
the paper size manually before starting the job. See below.

Selecting the Paper Size for Undetectable Sizes

Press the [Tray Paper Settings] key on the operation panel to select paper sizes
that are not detected automatically by the combination of paper size and paper
length sensor readings (marked " " in the table above and any other paper size
not listed that requires pulling out the paper tray extension).
NOTE: Mixed paper sizes cannot be loaded into the bypass tray. Loading paper of
different sizes will cause a paper jam.
