If it stops in the middle when using
A4 size or LTR size paper due to the
computer specifications, set to half

that paper perfectly straight without
any slant.
Operation Procedure
1) Clean feed path, roller, and reading
glass.
2) Place a piece of the registration
adjustment sheet you prepared. Make
sure to set the document guides to fit the
sheet to prevent skews.
Note:
The black edge needs to be
detected as the leading edge of the
sheet with the front side reading
sensor. Place the sheet so that the
black edge is the front and the
leading edge when fed. If both sides
have been filled with black, then
either side can be fed as the leading
edge. Do not place extra sheets.
