4.2.2 Ink Jet Printing Mechanism
4.2.2.1
Paper pulling-in, registration, feeding, and ejecting mechanisms
The paper pulling-in, registration, feeding, and ejecting mechanisms are driven by a single paper
feed motor located at the left side of the main chassis via the two PF timing belts and gear train.
(See the illustration given on the next page.)
First, the paper feed motor rotates counterclockwise (when viewed from the output gear). The
rotation is transmitted via the PF timing belt L to the PF roller pulley that rotates the paper feed
roller. At the right end of the paper feed roller is the PF roller gear R which is always engaged with
the ASF/purge idle gear. Engaged with the ASF/purge idle gear, the ASF-purge switching gear 23
transmits the rotation via gear 25 and ASF gear train to the ASF roller ASSY. This way, the ASF
roller will pull in paper.
When the ASF roller is pulling in paper, the paper feed roller rotates in the backward direction to
register the leading edge of the pulled-in paper.
Next, the paper feed motor rotates clockwise to rotate the paper feed roller in the forward
direction. The paper will advance through the paper path. During the paper feeding operation, no
rotation is transmitted to the ASF roller because of the planetary gear system built in the ASF
roller ASSY.
The above paper pulling-in and feeding operations take place when the carriage is in printing
operation. If the carriage reaches the purge position, the ASF-purge switching gear 23 will be
disengaged from the gear 25 and engaged with purge bevel gear A. For the purging mechanism,
refer to Subsection 4.2.2.3.
