Mechanism for Opening/Closing Tray
For the 500 option, when the main tray of KARA-S is opened and paper is loaded, the Bell-
crank spring [2] pulls the Bell-crank spring arm [4]. The shaft pin [3] connected supports
Accufeed arm A
’ssy [1] and holds it in place.
When the loaded tray is closed, the structure of the tray [5] presses the Bell-crank spring
arm [4] and no longer supported by the shaft pin [3]. Accufeed arm
A’ssy [1] falls
automatically, making the pickup roller fall onto paper..
Paper can be fed after this process.
Feeding/ Transfer Mechanism
When a feeding signal is entered from the main body, the pickup motor of the selected tray
begins to operate. The pickup roller rotates, picking up the top sheet into the main body.
Paper fed by the feeding pressure during Accufeed arm
A’ssy operation is separated in the
separation dam, and paper is fed one at a time.
The pickup roller rotates, feeding the front part of the paper to the transfer roller. Paper is
then fed through the transfer roller, past the mid roller in the main body. The pickup roller
rotates up to the number of encoded rotations set each time.
