Error Message (CS2436-12)
Note
To disable this message (if it is displayed repeatedly despite reloading
paper, for example), choose Off or Loose in the Skew Check Lv. setting of
the printer menu. However, this may cause jams and printing problems
because paper may be askew when printed. Also, the Platen may become
soiled, which may soil the back of the next document when it is printed.
Follow these step to
reload a sheet.
1. Push the
Release Lever
back.
2. Pull out the
sheet.
3. Pull the
Release Lever
forward.
4. Reload the
sheet, aligning it
