BACKUP BAR (Final-Under Power)
Requirement
The overall printing density shall be uniform and acceptable across the full width of the page. If the
whole character is present and legible, some variation in density is allowed, provided the density
variation is not consistently repeated.
Note: When the unit is properly adjusted for acceptable density, adequate ribbon life will also be
achieved; however, if the printer is adjusted for darker density levels, ribbon life will be proportionately
reduced.
