Paper Handling
The following section guides you through problems in handling single sheets and continuous paper. If you are having problems using the optional cut sheet feeder or pull tractor, see the section on options later in this chapter.
Problem Solution
Single sheets do not feed properly.
The LOAD/EJECT button was pressed, but the platen did not move and paper was not fed.

Paper Handling
Problem
Single sheets do not feed properly
(continued).
The LOAD/EJECT button was pressed and the platen rotated, but paper was not fed.
When the LOAD/EJECT button is pressed, the paper jams.
Solution
The paper release lever may be set in the wrong position. Push paper release lever back to the single-sheet position. See
Chapter 2.
The left and right edge guides may be too close together, preventing the paper from feeding smoothly. Adjust the position of the edge guides so that the paper can move up and down freely. See Chapter 2.
The paper may not be firmly inserted.
When feeding thicker than normal paper, press down lightly on the paper while pressing the LOAD/EJECT button.
The cut sheet feeder mode may be turned on (DIP switch 1-8 is on). When the cut sheet feeder is not in use, DIP switch 1-8 should be off. See Chapter 3.
The edge guides may be too far apart.
Adjust the edge guides to the width of the paper.
The dimensions of the paper may exceed the specified limitations. Use only paper sizes that are within the specified range.
Multi-part forms cannot be used with this printer’s single-sheet feeding system. See
Chapter 8.

When printing on single sheets, use the paper guide in its upright position.

Problem
Continuous paper does not feed properly.
When the LOAD/EJECT button is pressed, the platen does not rotate and paper does not feed.
When the LOAD/EJECT button is pressed, the platen rotates but paper does not feed.
Solution
You may be trying to feed paper using the control panel buttons while the printer is on line (ON LINE light on). Press the ON
LINE button once to set the printer off line, then try feeding paper. After feeding paper, press the ON LINE button again to set the printer on line. See Chapter 3.
The paper release lever may be pushed back to the single-sheet position. When using the tractor, be sure the paper release lever is pulled forward to the continuous paper position. See Chapter 2.
Continuous paper may have already been in the paper path. (In this case, the paper feeds backward to the standby position.)

Paper Handling
Problem
Continuous paper does not feed properly
(continued).
The paper feed is crooked or the paper jams.
Solution
The paper supply may be obstructed by a cable or some other object. Make sure that the paper feeds smoothly into the printer.
See Chapter 2.
Your supply of continuous paper may be too far from the printer. Position your paper supply within 3 feet (1 meter) of the printer. See Chapter 2.
The paper may be caught on the edge guides. When using continuous paper, make sure that the paper guide is lowered to the horizontal position and that the edge guides are positioned as far apart as possible. See Chapter 2.
The holes on the sides of the paper may not be aligned with each other. Reposition the paper on the tractor pins. See Chapter 2.
The sprocket units are incorrectly positioned for the paper width. Move the right sprocket unit to remove any slack across the width of the paper. See Chapter 2.
The position of your paper supply may be preventing it from feeding straight. See
Chapter 2.
7-18 Troubleshooting
Paper Handling
Problem
Continuous paper does not feed properly
(continued).
The paper feed is crooked or the paper jams (continued).
Regular gaps occur in the printout.
Solution
The sprocket lock levers may be unlocked, or the sprocket covers may be open. Position the sprocket units to match the width of your paper. Then, lock them in place by pressing the sprocket lock levers away from you. See Chapter 2.
The paper guide may be in the upright position. When using continuous paper, make sure that the paper guide is in the lowered position so that it can act as a paper separator. See Chapter 2.
The paper thickness lever may be in the wrong position. For printing on ordinary paper, always set the lever to position 2.
The paper dimensions may exceed the specified limitations. Use only paper sizes that are within the specified range. Your printer can print on continuous multi-part forms consisting of 1 original and 1 or 2 copies. See Chapter 8.
Skip over perforation may be interfering with your application program settings.
Set DIP switch 2-3 to off.
Troubleshooting 7-19
Paper Handling
Problem
Continuous paper does not feed properly
(continued).
Skip over perforation is set, but the perforation does not fall in the center of the skip.
The loading position of the paper shifts slightly while printing several pages.
Solution
The loading position of the paper may be too high or too low. Use the microadjustment to reset the loading position.
After printing stops, the paper automatically feeds forward.
The short fear-off function is selected
(DIP switch 2-2 is on), but it does not work.
The paper you are trying to feed may be too heavy for the built-in push tractor.
When highly accurate paper feed is necessary, such as when printing carbon copies, use the optional pull tractor.
The short tear-off function may be selected. When you resume printing, the paper feeds backward to its loading position. If you do not need this function, set DIP switch 2-2 to off. See Chapter 3.
There may still be data in the print buffer.
The short tear-off function works only if the data in the print buffer is completely printed and the next print position is at the top of the next page.
Your program may not be sending a form feed command to the printer. At the end of your program or the page, send a form feed (FF). If you are using BASIC, be sure to add a semicolon (;) after the FF code to prevent any additional codes from being sent to the printer.

Problem
Continuous paper does not feed properly
(continued).
The LOAD/EJECT button is pressed to eject the paper, the paper feed stops, and paper does not fully eject or it jams.
Solution
You may have tried to back feed too many pages. Before ejecting the paper, always tear off the last printed page. See
Chapter 3.
You may be trying to eject labels. Labels may jam when they are fed backward, so always use the FORM FEED button and feed labels forward to eject them.
Switching between single sheets and continuous paper cannot be performed properly.
When the LOAD/EJECT button is pressed to load continuous paper, the platen does not rotate and the paper is not loaded.
Pull the paper release lever forward to the continuous paper position, set the paper, then press the LOAD/EJECT button.
Troubleshooting 7-21
Paper Handling
Problem
Switching between single sheets and continuous paper cannot be performed properly
(continued).
The paper release lever is correctly set for continuous paper, but when the LOAD/EJECT button is pressed, the platen rotates backward and the paper comes off the sprockets.
When the LOAD/EJECT button is pressed to load a single sheet from the sheet guide, the platen rotates in reverse, the single sheet does not load, and the continuous paper comes off the sprockets.
Solution
A single sheet may be in the paper guide, causing the continuous paper to back out and to come off the sprockets. When using continuous paper, always make sure to remove any single sheets remaining in the paper guide.
The paper release lever may not be in the proper position. Push the lever back to the single-sheet position.
