Operation Manual

1.1.3 Advanced paper feed function
To improve the paper feed speed, this printer has an advanced paper feed function.
With this function, when multiple pages of plain paper with a page length longer than
letter-sized paper, are printed in HS mode, the printer begins feeding of the next page
before ejection is completed.
1.1.4 Paper feed retry function
To improve the paper feed capability, this printer has a paper-feed retry function.
When paper feeding is detected to be improper (refer to items (a) and (b) described
below), the printer will reattempt paper feeding with this function. If proper paper feed
cannot be realized after retrying once, the paper feed error will result. This function is
performed when (a) or (b) is fulfilled:
(a) If no paper is sensed by the paper end sensor, paper pick-up operations will be re-
executed.
(b) When the pick-up roller sensor cannot detect the pick-up roller flag, even after
rotating the pick-up roller of the ASF with a set number of pulses, if the paper has
reached the paper end sensor, it will be ejected, and the paper pick-up operation
repeated.
1.1.5 The print start position adjustment retry function
To improve the accuracy of the print start position, this printer has a print start
position adjustment retry function.
The printer uses this function when printing in HS mode.
When paper is not detected to be properly delivered to the print start position
correctly (refer to item (a) described below), this function will move the paper
automatically to the correct print start position.
(a) When the paper end sensor does not detect the paper until the pick-up roller has
been rotated more than the prescribed number of pulses, the printer will determine
that the paper is not at the correct print start position.
In this case, the rotation of the paper feed roller is reversed to perform the form
alignment function, and the paper will be moved to the correct print start position.
1.1.6 The form alignment function
To improve the paper feeding capability such as reducing skew, this printer has a
form alignment function. The printer uses this function when printing, except when
printing in HS mode. However, if the print start position adjustment retry function
has been performed, this function can be used in HS mode.
The paper is pressed to the paper feed roller and the pressure roller, which are
turning in reverse to create a bend in the paper. With this bend, the paper will be fed
in a straight path, even if it was set askew.
