60 dots per inch;
480 dots per 8” line
816 dots per 13.6” line
120 dots per inch;
960 dots per 8” line
1632 dots per 13.6” line
Same density as
Mode 1, but faster.
The printer does not
print consecutive dots
in any one row.
240 dot position per inch;
1920 dot position per 8”
line;
3264 dot position per
13.6” line
The printer does not
print consecutive dots
in any one row.
80 dots per inch;
640 dots per 8” line;
1088 dots per 13.6” line
Matches the screen
density of the QX-10:
(This makes it easy to
do screen dumps.)
72 dots per inch
576 dots per 8” line;
979 dots per 13.6” line
Produces the same
density horizontally
as vertically, which
makes circles look round
90 dots per inch:
720 dots per 8” line;
1224 dots per 13.6” line
144 dots per inch
1152 dots per 8” line
1958 dots per 13.6” line
Twice the density
of Mode 5
the IBM mode.

This chapter uses the term dot positions instead of dots for two
densities: high-speed double and quadruple. Because the FX-286 does
not print consecutive dots in a row in these densities, it cannot print
dots in all the possible dot positions in any one row. For example, an
eight-inch high-speed double-density row has 960 places where the
