controller when a print request is made does not match the results of OHP Sensor (PC2A)
detection, the machine suspends the print cycle and displays a corresponding message on the
control panel.
Size Error Detection Control
■ To prevent incorrect printed pages, the size of the paper being conveyed is detected using
the Registration Sensor (PC1).
■ The length of the paper is detected based on the value calculated using the period of time
that begins when the sensor is activated and ends when it is deactivated.
■ If the paper size specified by the controller does not match the paper size detected by the
Registration Sensor (PC1), the machine displays a corresponding message on the control
panel.
■ The paper that has caused the size error is processed through the printer. Subsequent
sheets of paper are stopped until the size error is corrected or the job is cancelled.
