HP 2566C - Manual (Page 91)

For draft quality print:
1. Run sub-test 10.
Close the swing-gate and initiate sub-test 10, which prints one page of
ripple print (see page 5-8 for sub-test procedure).
2. Adjust the forms thickness.
Decrease the forms thickness setting toward “A” to obtain optimum
print quality. Adjust the setting until print quality is correct.
Note
Draft character sets require a smaller forms gap then the standard
character sets. In addition, forms tension is much more critical and
requires extra care to assure proper setting.

The draft character set increases the throughput of the HP2567C from
1200 to 1600 lines-per-minute (1pm) and the HP2566C from 900 to 1200
1pm. It does this by printing characters that are 5 dots high and 4 dots
wide in the same space that the standard symbol set prints a character
7 dots high and 5 dots wide. In most cases, the dots in the vertical
direction will not be connected. This is fundamental to the design, not
an indication of improper adjustments on the part of the operator or
field service personnel.
Preventive
Maintenance
Maintain the printer in a state of general cleanliness. Accumulated dust,
bits of paper, and lint can lead to serious problems.
Watch for indications of physical damage and report problems or
potential problems to your Hewlett-Packard Service Representative.
