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 ES-
Cape 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 pro-
grams 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” sec-
tion 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.
