Paper Size Detection - Ricoh D699 Field Service Manual

Paper Size Detection

There are three paper size sensors [A] (SN1, SN2 and SN3) on the paper tray unit. Each paper tray
has its own actuator [B], with a unique combination of notches. This actuator is moved when the paper
end fence [C] is adjusted for the installed paper. To determine which size has been installed, the CPU
reads which paper size sensors the actuator has switched off. Refer to the size detection lists as shown
below.
