OHP transparencies detection control

• To prevent incorrect prints on OHP transparencies, the type of the media being conveyed
is detected by the OHP sensor.
• The OHP detection is made after the loop has been formed in the media before the reg-
istration roller.
• If the output voltage of the OHP sensor is less than a predetermined value, the main
body considers that the media is a type other than OHP transparencies. If the output volt-
age is the predetermined value or more, the main body determines that the media is
OHP transparencies.
