Error Code 17

Wrong Paper Size / Wrong Paper

Recording paper size error (duplex-printing/duplex-copying)

- Paper width is wider than 301.5 mm (detection by paper width sensor .)
- Paper width is narrower than 95.5 mm (detection by paper width sensor .)

- Paper length is longer than 245.9 mm

(detection by registration sensor , switchback sensor.)

- Paper length is shorter than 143.5 mm

(detection by registration sensor , switchback sensor.)
User Check
- Check whether the recording paper being used is within the specification.
- Check that dark recording paper is not used.
- Firmly set the paper tray to the rear end.
