Character Scrunch
When the printed characters appear somewhat squatty or scrunched,
it is referred to as “Character Scrunch” (Figure 7-1, A). Character
scrunch signifles that the paper tension is too loose. Adjust the vertical
paper tension lever towards the letter “N” one position at a time (refer
to “Adjusting Vertical Paper Tension,” page 3-15) until all character
rows have correctly formed characters (Figure 7-1, B). Run sub-test 9
(a pattern of upper case characters) by following the procedures on page
3-24, to verify overall print qualify. Continue running sub-test 9 and
adjusting the setting until the best print qualify is obtained.

Printer Errors All fault conditions are signified by flashing numbers in the display
window on the Operator Control Panel. These error indications are
provided to help you locate and possibly correct problems which prevent
normal operation of the printer. When any fault condition exists, the
printer automatically goes “off-line” and cannot be put “on-line” again
until the fault is corrected.

10 through FF. There are several categories of errors;
Operator correctable errors - error numbers 10, 11, 12 and 13.
