Printhead Pressure Adjustment - Intermec EasyCoder PD4 User Manual

Printhead Pressure Adjustment

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 fix 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 flipping it
counterclockwise a quarter of a turn.
4 Use a straight-slot screwdriver to turn the screw at the top of the bal-
ance boxes clockwise to increase the pressure or counterclockwise to
decrease the pressure.
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.)
