3. Paper size detection
The side fences [A] can be adjusted to standard and non-standard
paper sizes.
Paper size is measured with the paper width switch [B] and the
paper length sensor [C].
When the side fences are moved to match the paper width, four
feelers inside the paper width switch [B] slide along the wiring pat-
terns on the paper width switch terminal plate. The status of each
feeler is read to determine whether it is High (in contact with a pat-
tern wire) or Low (not in contact with a wire).
The paper length sensor reading (ON or OFF) is used with the
paper width reading to determine the paper size. For more details
about how the paper size is determined, see the paper size detec-
tion table on the next page.
The paper end sensor [C] de-activates when the last sheet is fed,
reports that the paper tray is empty, and halts the job.

B. 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 combi-
nation 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).
select paper sizes that are not detected automatically by the combi-
nation 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.

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
adjusted to fit the size of the paper loaded in the tray. The H, L
status of each
feeler is determined by whether the feeler is in contact with
the wire of a pattern.
