Chapter2 Operating Principles
In the paper pick up mechanism of Stylus Color 600, same mechanism as Stlylus Color IIs/820
are applied. This mechanism changes adjoined lines of gear by colliding trigger lever with carriage
unit and convey the motive power on the platen to the ASF side(paper roller). The figure below
shows mechanism with explanation.
[2. Paper pick up mechanism]
When the Load/Eject switch is pressed or printing order is input, the carriage unit moves until
the left edge and collides with paper pick up trigger lever. When the carriage collides with this trigger
level, a planetary gear located on the same axis is also pushed at the same time and conveys
the motive power on the platen to the adjoined gear line side for ASF drive.

[3. Paper feed mechanism]
After papers in the ASF receive controls from pick up and multi feed prevention mechanism, they are
sent to the printer inside. The papers picked up by paper roller in the ASF goes to between platen
and roller support. Also, the eject roller pushes out the paper completely until the end and the roller
support drops the paper in the eject tray. The eject roller is driven with an eject paper notched roller as
pair where is located on the paper eject roller. Paper eject notched roller solves the deflection of paper
that is in the between platen eject notched roller and paper eject roller and always keep a certain space
between print head and paper surface. The figure below shows paper feed mechanism.
