3.4 Replacing the Print Head

The print head on the M-5900RV is a user-replaceable item. This section
explains how a defective print head can be easily removed and replaced.
Contact you local SATO representative for information on obtaining a new print
head.
NOTE: The print head contains a precision printing surface that must be
carefully protected from mechanical damage. Extreme care must be exercised
during handling and installing to prevent scratching, chipping, denting or
otherwise damaging the exposed substrate surface, particularly in the resistor
(printing element) area. A small clean piece of cardboard should be used to
protect the substrate during installation if there is a possibility of accidental
damage.
Supplies needed:
• Small .lathead Screwdriver
