Intermec EasyCoder PD4—Service Manual
Printhead Balance
The printer is factory-adjusted for full-size media width. When using
media less than full width, it is recommended that you adjust the position
of the printhead balance boxes so the printhead gets an even pressure across
the media.
A poorly adjusted printhead pressure may be detected by a weaker printout
on either side of the media path.
To adjust the pressure, proceed as follows:
1 Open the top cover.
2 Remove the ribbon.
3 Lift the printhead by pulling out the printhead lever and fl ipping it
counterclockwise a quarter of a turn.
4 Move the balance box on the right side (outer) outward (to the right) for
wider media and inwards (to the left) for more narrow media.
5 Engage the printhead and load the ribbon.
6 Test and readjust if necessary. (Hint! If you use direct thermal media you
will not have to load and remove the ribbon over and over again.)
Printhead Pressure
The pressure of the thermal printhead against the platen roller is factory-
adjusted. However, if the printing is weaker on one side of the media or if
the thermal transfer ribbon starts to crease (indicated by unprinted white
streaks along the media feed direction), it may be necessary to readjust the
printhead pressure.
Note: Before readjusting the pressure, try to fi x the problem by moving the
outer balance box as described earlier in this chapter.
1 Open the top cover.
2 Remove the ribbon.
3 Lift the printhead by pulling out the printhead lever and fl ipping it
counterclockwise a quarter of a turn.
