Block Handle
Printhead pressure block adjustments are used to obtain a uniform print density across the width of the
installed media under a variety of media and ribbon conditions.

Left Pressure Block

Under normal printing conditions, the left block should be set with its handle aligned with the bold mark on
the pressure block adjustment scale. When using media or ribbon widths less than one-third the printer's
maximum printing width, you may need to manually slide the left pressure block further to the left.

Right Pressure Block

The right pressure block should be positioned with its pointer (handle on 4 inch printer models) near the
right edge of the media or ribbon in use. Turn the lead screw knob clockwise to move the block right or
counterclockwise to move it left.
Check the pressure block positioning by printing the Grey test pattern:
1. Press the PAUSE key to place the printer OFFLINE (Home Screen).
2. Go into the "Settings" section.
3. Select the "Grey" print test under Tools > Print Tests > Run Test.
