BJC-7100

3.5.2 Paper feed/sheet feeder mechanism structure

The sheet feeder of the BJC-7100 printer has no mechanical paper selection lever. Provided the print media is within the specifications, the media is fed without having to adjust the carriage position, etc., for the paper thickness.

The print media is loaded into the sheet feeder with the two points of the leading edge and the left corner picked up by the pickup corners and pickup hooks. When the drive from the paper feed motor is transferred to the sheet feeder gear, the pickup roller turns and the printer starts printing.

Print media such as plain paper are fed while pressed against the pickup corners and pickup hooks and fed into the paper feed mechanism. When feeding stiffer materials such as envelopes, the rigidity of the paper is sufficient that the pickup hooks and pickup corners are pressed down and the material can be fed.

The initial position of the pickup roller is determined by the pickup roller sensor (photointerrupter) on the logic board sensing the flag.

When the print media is detected by the paper end sensor, it is automatically fed to the top-of-page position. If no print media is detected even after a feed operation, a paper-out or paper-jam error message is displayed. When manually feeding paper, the user manually inserts the print media via the manual feed slot until it reaches the paper end sensor.

Because manually fed print media are fed through a different path than media automatically fed from the sheet feeder, print media can be manually fed even when media are loaded in the sheet feeder.

Print media that has been fed to the paper feed mechanism are fed to the top-of-page position when the paper end sensor has sensed their existence for two or more seconds.
