3.5Paper Feed/Sheet Feeder Mechanism

3.5.1Paper feed/sheet feeder mechanism functions

1) Paper feed function

The paper feed mechanism has two paths: the path taken by sheets fed automatically from the sheet feeder mechanism and sheets fed manually through the manual feed slot. The built-in sheet feeder is driven by the paper feed motor, and loads and automatically feeds the print media. Even envelopes are automatically fed without the need to operate mechanical paper select levers, etc. When pages are fed manually, the manually fed page takes precedence over any media loaded in the sheet feeder.

When the print paper is detected by the paper end sensor (photointerrupter), it is automatically fed to the top-of-page position on the platen by the paper feed roller. During printing, the page feed is controlled by controlling the rotation of the paper feed roller.

On completion of printing, the page is ejected by the paper output roller.

2) Auto platen-head gap adjustment function

The BJC-7100 printer can print without switching the carriage position according to the thickness of the media being printed on.

The paper feed roller is pressed up by coil springs toward the pressure roller while the paper output roller is also pressed up by coil springs toward the spurs. The gap between the head face and the printed media is therefore kept constant regardless of the thickness of the print media.
