2.7.3 OHP Side Detection Control

The printer detects the side (back/front) of the OHP set in the printer. If
the back side of the transparency is set facing the belt (top side), the
transparency will be rolled into the Heat Roll. The OHP Side Detection
Control function prevents an OHP film from being rolled up with the
Heat Roll. The printer detects the side of the OHP from the signals sent
by the Front OHP Sensor and the Rear OHP Sensor. Epson exclusive
OHP transparency film (S041175/4) has a white edge with a notch on it.
The sensors detect the notch and the printer determines whether the
film is set properly (based on the signals sent from the sensors). If any
OHP film other than specified one is used, the printer indicates the
message "Check OHP sheet" and stops printing.
