6.6.4 PAPER SIZE DETECTION – TRAYS 1 & 2
For tray 1, there is no size switch. The paper size is fixed at either A4 or LT; this
can be changed with SP1-902-1.
For tray 2, four paper size switches, working in combination, detect the paper size
as shown in the table below. The actuators are on the side plate [A]. The side plate
is moved by the end plate [B] through a cam [C].
