PAPER LOADING ERRORS


"Reload Paper" Error
After paper is loaded in the printer, the printer performs the left, right, and
leading edge detection operations described above. If the operations fail at
any point, a "Reload Paper" error occurs.


"Paper Not Straight" Error
To avoid printing on paper that is skewed or fed at a slant too far to the
right or left, the printer detects the right and left edges at the leading edge
of each page. If the printer determines that the paper is skewed 3 mm or
more from the position previously detected, a "Paper Not Straight" error
occurs.
To avoid paper loading errors, make sure the paper's left edge (near HP) is
lined up with the vertical line of holes in the Lower Paper Guide. Paper loaded
within 10 mm of the center of the vertical line of holes in the Lower Paper Guide
is considered in the printable zone; however, paper loaded outside that 10 mm
zone causes an error.
Technical Overview

2.2.3 Carriage Lock Mechanism

The printer uses an electromagnetic solenoid to release the carriage lock.
When the carriage lock does not receive any signal, the actuator rises into the
opening at the bottom of the subcarriage, restricting carriage movement. To
release the carriage for printing, the printer signals the actuator which then
moves down, releasing the carriage.
