    Loading Single-Sheet Paper The single-sheet paper path is best for letterhead stationery, memos, and envelopes. We also recommend it for printing graphs and charts because it provides the most accurate control of the paper. To load in single sheets of paper: If you have any continuous-form paper in the paper path, you must press the PARK button on the front panel to remove it from the path before lading single sheets.

    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 use the single-sheet paper path. To load continuous-form paper from the rear: 1. If you have paper in paper path, be sure to remove it before installing rear-feed paper.

  • Page 26: Paper Handling

    Paper Handling Your printer has several handy paper handling features: • Tear • Form Tear-off • Paper Park Tear Feature When you’re using continuous forms with either the built-in rear-feed tractor or the optional bottom-feed push tractor, you can use this feature to advance the forms up to the tear position so you can easily tear off a printed sheet without wasting paper or readjusting the printer.

  • Page 27: Forms Tear-Off Feature

    Forms Tear-off Feature Caution! Do not engage Forms Tear-off when printing on labels! The Forms Tear-off feature can be engaged to automatically move the paper up to the tear position after the selected interval (500 milliseconds, one second, or two seconds). The page will stay in the tear-off position until the printer receives data.

  • Page 28: Switching Paper Paths

    Switching Paper Paths To switch from continuous-form feed from the rear or bottom (optional push or pull tractor installed) of the printer to single-sheet feed from the top: 1. Tear off printed pages. 2. Press PARK button. 3. Swing wire guide up into paper separator, then pivot separator to upright posi- tion.
