Paper Size Detection - Ricoh B264 Service Manual

6.11.7 PAPER SIZE DETECTION

The paper size switch includes four microswitches. Actuators behind the paper size
dial actuate the switches.
Each paper size has its own actuator, with a unique combination of notches. To
determine the paper size, the CPU reads which switches the actuator had turned
off.
The CPU disables paper feed from a tray if the paper size cannot be detected. If
the paper size actuator is broken, or if there is no tray installed, the printer control
board recognizes that the paper tray is not installed.
When the paper size actuator is at the "✻" mark, the paper tray can be set up to
accommodate one of a wider range of paper sizes by using one of the user tools
on the machine's operation panel.
