Problem
Using the cut sheet feeder, the paper does not feed properly.
The LOAD/EJECT button is pressed, but the platen does not move and the paper does not feed.
After a print command is sent from the computer, the platen does not move and the paper does not feed.
Solution
You may be pressing the LOAD/EJECT button while the printer is on line.
Always put the printer off line before feeding the paper. Paper feeds automatically when the cut sheet feeder receives a print command from the computer (only while the printer is on line).
The printer may be off line. Press the
LINE button to put the printer on line.
ON
The cut sheet feeder mode may be off. Set
DIP switch 1-8 to on. If your program allows you to use control codes, use ESC
EM 4 to set the cut sheet feeder mode. The printer must be ready with no paper out condition to receive this command. Send the command with continuous paper loaded and with the paper select lever in the continuous position.

Problem
Using the cut sheet feeder, the paper does not feed properly
(continued).
After a print command is sent from the computer, the platen rotates, but paper does not feed. The PAPER
OUT light is on.
Solution
DIP switch 1-8 is set to off. DIP switch 1-8 must be set to on in order to use the cut sheet feeder. See Chapters 3 and 5.
The cut sheet feeder may be incorrectly installed on the printer. Remove and reinstall the cut sheet feeder making sure that the mounting notches are properly mated with the pins on the printer. See
Chapter 5.
The cut sheet feeder may be out of paper.
Load more paper in the cut sheet feeder’s bin.
The paper release lever may not be in the single-sheet position. Push the lever back to the single-sheet position. See Chapter 5.
The paper set levers may be pulled forward. After loading a stack of paper in the cut sheet feeder, push the paper set levers backward. See Chapter 5.
The left and right paper guides may be too close together, preventing smooth paper feed. Adjust the position of the paper guides so that the paper can move up and down freely. See Chapter 5.

from the cut sheet feeder’s bin.
The paper may be old or creased. Discard it and load new, clean sheets of paper.
The left and right paper guides may be too far apart. Adjust the paper guides to the width of the paper.
There may be too much outgoing paper.
Never let more than 80 sheets of outgoing paper accumulate while printing.
The weight of your paper may be too heavy or too light for the cut sheet feeder.
Refer to the specifications in Chapter 8 and make sure that your paper is the proper size and quality.
The single sheet may have been inserted in the wrong place. Check it and try again. See Chapter 5.
Paper may feed from the bin if you try to insert several single sheets. To insert several single sheets, pull the paper set lever forward.

Problem
Using the pull tractor with the push tractor, continuous paper does not feed properly
(continued).
Paper feed is crooked or the paper jams.
Solution
Something may be obstructing the paper feed, like an object on top of the paper stack or a cable caught on the paper.
Make sure that nothing prevents the smooth flow of paper and position the paper so that it feeds straight in line with the sprockets.
The supply of paper may be too far from the printer. Position the paper supply so that it is less than three feet or one meter away.
The paper may be caught on the edge guides. When using continuous paper, make sure that the paper guide is folded backwards over the paper and that the edge guides are moved to each edge of the paper guide. See Chapter 2.
The pull tractor and push tractor sprockets are not aligned correctly. When using both tractors, be sure that the sprockets on both are positioned evenly.
