Graphics
If you find strange dot patterns appearing in the middle of your
graphics, and at the end of the line of graphics there are text charac-
ters you did not intend, your computer may be sending a carriage
return and line feed when you did not expect them. You may need
to change the print width. See your computer document.
Many computers have problems sending one or more of the codes
between
O and 13. Try to avoid these characters if possible. You
may also be able to bypass the printer interface software which
removes some of these codes. Where solutions are known they are .
given later in this appendix,
Seven-bit computers cannot use the eighth pin (128). If any of your
graphics data numbers is larger than 127, you will have to redesign
the graphics.
Be sure that no other commands or carriage returns come between
the graphics command and its data. See Chapter 8.
If the printer "freezes" in graphics mode, you have sent a different
number of data codes from the one you specified in the command.
The printer expects a certain number of pin patterns, determined by
nl and n2. It will wait patiently until the quota is fulfilled. Take extra
care with 9-pin graphics mode since it requires two data bytes for
each column of graphics.
Problems with irregular darkness of printing
Check that the ribbon is seated correctly. It may need replacing if
you have been using it for a long time or for a large amount of
printing. It may occur in conjunction with the next problem.

Problems with paper feeding
If a self-adhesive label comes off the backing, it may stick behind the
platen causing problems with paper feeding and printing. If this
happens, take your GX-80 to a qualified service person or your
dealer. Do not attempt to remove the label yourself.
SelecType Solutions
If you have found that your software sends a resetting code and
wipes out your SelecType settings, one of the following methods
should help you find a way around the problem.
Method 1
Use the installation program for your software to remove the in-
itialization code. See your software manual for details. Choose
Epson FX, RX or MX option to use GX-80.
Method 2
Without using SelecType, give your program the command to print
your document. Then, before the printing actually starts, give the
command to stop printing. Now use SelecType to select the type-
style you want as in the following example for setting condensed
mode:
1) Make sure that both the ON LINE and READY lights are on.
2) Press the ON LINE and FF buttons at the same time.
3) Press the ON LINE button four times (the code for condensed).
4) Press the FF button to set condensed.
5) Press the LF button to exit SelecType.
6) Press the ON LINE button.
Now give your printer the command to resume printing. If your
example is now in condensed, you can use this same sequence each
time you want to use SelecType. The procedure is not complicated.
Once you have practiced it a few times, you will have fingertip
control of your printing.
