2.3.2 DETECTION TIMING
When the mailbox exit sensor goes high for the prescribed time (T), the machine
determines that the tray is full. The value of T is calculated, regardless of paper
size, as follows:
T (s) = (60/s x max. size ppm) x 3 s
After the tray full sensor switches on, if it remains on for the feeding of eight
additional sheets, then this notifies the machine that the tray is full.
“T” is calculated as shown below. For example, for a minimum ppm of 12 prints
(regardless of paper size), the value T is 15 s. Then, if the sensor detects paper for
15 s or more, the machine stops the copy job.
