MECHANISM
1. Paper feed tray elevation mechanism
Paper detection sensor confirms whether paper is set on the Paper feed tray.
By pressing the print START button when the Paper detection sensor is ON (paper is detected), the
elevator motor is activated to bring up the paper feed tray until the Scraper plate assembly blocks the
light path of the Upper limit sensor.
The Elevator motor is activated intermittently during the printing job to keep the Upper limit sensor
light path blocked.
When the paper runs out from the Paper feed tray (the Paper detection sensor becomes OFF), the
Elevator motor is activated to bring the Paper feed tray down.
During the machine idle condition, if the Paper feed tray button is pressed, the elevator motor is
activated until the tray lowers down to the Lower limit position in which the light path of the Lower limit
sensor is blocked.
