Problem Continuous paper does not feed properly (continued). The short tear-off function is selected (DIP switch 2-7 is on), but it does not work. 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 not have turned off the power after setting the DIP switch. To make new DIP switch settings effective turn the power off, then on again. 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. You may have tried to back feed too many pages. Before ejecting the paper, always tear off the last printed page. See Chapter 2 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. Troubleshooting 7-23
