    BJC-6500 Part 5: REFERENCE 1. TECHNICAL REFERENCE 1.1 Functions of the Paper Feed Unit The paper feeding function of this printer is to feed the print media from the Auto Sheet Feeder (ASF) through to the print start position. The ASF is driven by the paper feed motor, and automatically feeds the print media. When the print media has been detected by the photo-interrupter type paper end sensor, it is fed to the print start position on the platen via the paper feed rollers.

    Part 5: REFERENCE BJC-6500 1.2 Construction of the Paper Feed Unit The BJC-6500's paper feed unit is comprised of the paper pick-up unit, paper feed unit, and the paper eject unit. Its' construction is different from that of the BJC-6100, as explained below.

  • Page 93: Form Alignment Function

    BJC-6500 Part 5: REFERENCE 1.3 Form Alignment Function In order to improve the paper feeding capability of the BJC-6500, such as reducing skew, the printer has a built-in form alignment function to detect the top of fed media. The form alignment function allows paper to press against the paper feed roller to create a bend in the paper, and this bend forces the leading edge of the paper to become aligned to permit straight-line feeding.

    Part 5: REFERENCE BJC-6500 1.4 Transmission Gear Unit Depending on the carriage position, the transmission gear unit switches the paper feed motor's drive power over to drive the purge unit or the auto-sheet feeder. The slide arm that moves with the carriage action controls the timing of the switching and the operation.

  • Page 95: Detection With Sensors

    BJC-6500 Part 5: REFERENCE 1.5 Detection with Sensors This printer has the following sensors to detect the printer's status. In the BJC-6500, to more accurately detect the pick-up roller's position, a photo- interrupter type ASF sensor has been added. With the ASF sensor, as the pick-up roller's position can be detected, incorrect pick-up roller position during initialization and paper pick-up operations can be detected.
