The paper size switch [A] detects the paper size. The paper size switch has
five microswitches inside. The paper size switches are actuated by an
actuator plate [B] located on the rear of the tray. The actuator is slid across
to match the paper size. Each paper size has its own unique combination of
switch states, as shown in the table. The CPU determines the paper size by
the signal combination from the switch assembly.
Using SP5-019, the first tray can be set up to accommodate one of a wider
range of paper sizes. If this is done, the readings from the first tray’s switch
assembly are ignored. If a different size paper is used without changing
SP5-019, paper jams will result.
