Loading Rear-Feed Paper
The rear-feed paper path is recommended for single-thickness, continuous fan-fold
paper when printing spreadsheets, long reports, etc. For graphics or charts, it’s best to

1. If you have paper in paper path, be sure
to remove it before installing rear-feed
paper. To remove single sheet, press FF/
LOAD button. To remove bottom-feed
paper, press PARK button.
2. Move paper lever to position marked
“REAR”.
3. Open the access cover, hold up the knob
of the paper separator, and remove the
paper separator.
