2-16 Outline of Operation Rev. A

Confidential

Step 2

The shutter motor now turns in the CCW direction, returning the shutter mechanism to home

position. The paper-feed motor then starts again, feeding the leading edge of the paper to the

point where it is just about to reach the top slip holder guide ("Paper guide, slip hold, top").

Step 3

The shutter mechanism reaches the phase point indicated as T2 in the timing chart. At this point

the shutter has risen almost to the level of the slip holder paper guide, and the slip holder plate

("Holder plate, slip") is pressing the end of the slip against the platen so that it does not come

loose. Further feeding of the sheet advances it all the way to the top slip holder guide.

The shutter mechanism is returned to the home position; then printing begins.
