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
This 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 until "OFFLINE" appears on the LCD.
2. Press the TEST PRINT key until "Printer Tests/Grey" displays.
