Tally Dascom 2600 2610
10
The ‘head gap’ is the distance from the tip of the needles to the Print Bar.
Ex-factory value with the Gap Lever set at 1 position is between 0.40~0.44 mm.
This mechanical adjustment requires thickness gauges instead of changing the
positions of the Gap Lever. This adjustment sets the datum/standard level. A
deviation from the datum affects the print quality, ribbon jam and lost steps in the
carriage
motor.
