1, 2, 3, The paper width switch consists of 5 feelers that slide along the wiring patterns of the paper
4, and width switch terminal plate when the side fences are manually adjusted to fit the size of the
5 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.
H High (5 V) (Inactive)
L Low (0 V) (Active)
The machine determines the paper size automatically by reading the output of the paper
width 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
Selecting the Paper Size for Undetectable Sizes
Press the [Tray Paper Settings] tab on the operation panel to select paper sizes that are not detected
automatically by the combination of paper width 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).
Mixed paper sizes cannot be loaded into the bypass tray. Loading paper of different sizes will cause a
paper jam.
