Epson FX-286 User Manual - Page 110

Paper advancing If the printer advances the paper several pages at the end of each page of printing or each time it receives a form feed, see that DIP switch 2-2 is OFF when you are not using the optional cut-sheet feeder. Tabbing Remember to set margins before tabs, not after. Paper-out sensor will not turn off Some computer systems ignore both the DIP switch and the ESCape code that deactivate the paper-out sensor. See ESCape "8" in Appendix G or J. Self-adhesive labels If you're printing labels and a self-adhesive label comes off of the backing, it may stick behind the platen and cause problems with paper feeding and irregular darkness of printing. If this happens, take your FX-286 to a qualified service person; do not attempt to remove the label yourself. Graphics Solutions There are three common sources of problems with graphics programs in BASIC: 1. Unwanted codes for carriage returns and line feeds may be inserted by BASIC if lines are over 80 columns long or if semicolons are not used at the end of program lines between the graphics command and its data. See Chapter 6 for the proper format for a WIDTH statement and for sample programs that show the proper use of semicolons. 2. Some software will not send certain codes. For example, IBM PC BASIC will not send CHR$(26). Read the "Hex Dump Mode" section in this appendix for further information. 3. If the printer stops during a graphics program, it may not have received enough data. The printer expects a certain number of pin patterns, determined by n1 and n2 in the graphics command. It will wait patiently until the quota is full. Note that nine-pin graphics (Epson mode only) require two bytes for each column of graphics. C-2
