Product Description
Paper skew check
Feeds a specified amount of paper for checking the skew level, and detects the
Position paper edge before and after feeding with the sensor to check the
error.
When the paper feed amount is entered after the paper initialization, the edge
sensor detects the left edge of the paper (home position side) after feeding
operation and the printer displays the difference with that of before feeding on
the panel.
The first paper edge detection determines the paper skew judging standard
position in the firmware.
NOTE 1: If the paper check LED blinks/lights, the paper detection error
currently occurs. In this case, perform the paper skew check again
after releasing the lever once.
2: If the skew result indicates [99.999mm], it could be caused by the
following reason(s). In this case, perform the paper skew check
again after removing the cause(s).
• The paper width has been changed by
paper edges compared with the previous paper width detection.
• The paper is loaded too close to the home position side.
• The lever is pulled up or the cover is opened during paper feed.
3: The panel keys are invalid during paper skew check.
4: For the indicated value, "+" indicates the home position side and "-
"indicates the other side.
