2.1.1.1 Paper
There are two methods of feeding the paper into the printer. One is by using the multi-purpose
tray (standard
cassette. While paper is in the tray or cassette, the detection lever for the paper empty sensor is
lifted. When the paper supply runs out, the detection lever is lowered, causing the shutter to
interrupt light from the LED to the photo-transistor. This causes the signal to go HIGH, informing
the engine driver that the paper tray or the cassette is empty.
When the paper take-up solenoid is actuated, the paper take-up roller rotates and feeds the first
page. The paper take-up roller stops after one rotation. Unlike the EPL-7@l(3/71MI/75M and
synchronizing roller installed. The timing to align the leading edge of the page with the image is
detected by the paper take-up sensor.
When the page is on top of the paper take-up sensor, the detection lever is lowered, allowing light
from the LED to reach the photo-transistor. This causes the signal to go HIGH, informing the
engine driver that paper has been detected.
The paper exit sensor is located beyond the fusing roller in the paper path. When paper passes the
paper exit sensor, the detection lever is lowered, allowing light from the LED to reach the
photo-transistor. This causes the signal to go HIGH, informing the engine driver that paper has
been delivered.

Multi-Purpose Tmy (Standanl Troy)
The paper guide can be moved to fit against the sides of various sizes of paper, allowing the paper
to be fed.
Although the paper take-up roller stops after one rotation, the transport rollers continue to fed the
first page, because these rollers are independent of the paper tak~up roller. At this time, the
depression cam attached to the paper takeup roller depresses the paper lift-up plate to prevent the
feeding of a second sheet.
