Adjust Printhead Pressure
MP Compact4 Mark III User Guide
To accommodate a variety of media types, printhead pressure is adjustable.
This pressure is factory set to work with most media types, so this adjustment
should only be performed after attempting to improve print quality through
increasing the printer's heat setting or decreasing the print speed setting.
When adjusting, use only the minimum pressure necessary for better imaging.
1 Lower the front panel.
2 Load at least 102 mm (4") wide media, see
3 Print a test label from the host. Choose a label format with content that
spans the width of the label.
4 Unlatch the printhead. Turn the pressure adjustment screws (item 1)
counter-clockwise to increase the applied pressure or clockwise to decrease
it. Make equal adjustments to each screw to achieve even print contrast
across the media.
5 Re-latch the printhead and repeat the test print. Repeat step 4 until an
acceptable print has been achieved.
Note: When using narrow media, it is necessary to reduce the pressure on the
outer (right) pressure adjustment screw and increase the pressure on the inner
(left) pressure adjustment screw. This will prevent damage to the exposed areas
of the printhead and platen roller.
Excessive pressure can reduce the service life of the printhead and platen
roller, while unequal pressure may cause faded print and label tracking
problems.
