■ Error Code 1700
Recording paper size error (duplex-printing/duplex-copying)
- 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)
- Paper length is shorter than 143.5 mm (detection by registration sensor)
< User Check >
- Check whether the recording paper being used is within the specification.
- Check that dark recording paper is not used.

■ Error Code 1800
Paper jam during duplex-printing
Registration sensor does not detect paper feed within specified pulse numbers in the
second side paper re-feed.
< User Check >
- Remove the jammed paper.
- Check whether the recording paper being used is within the specification.
- Check that recording paper are not curled, wrinkled or wet.
