Ribbon Rewind Unit
Print Unit
Backing Paper Rewind Unit
Intermec EasyCoder 601 XP – Service Manual Ed. 3
The print unit is partly integrated with the ribbon rewind unit (see
chapter 7.3) and the optional backing paper rewinder unit (see
chapter 9).
(option)
The main parts of the print unit are:
• The rubber-coated pressing roller drives the paper forward
under the printhead and provides the necessary counter-pres-
sure.
• The stepper motor drives the pressing roller via one belt and the
ribbon return roller and the ribbon rewind unit via another. The
rewind roller is idle, unless a backing paper rewind kit is fitted,
see chapter 9.
• The tear-off edge makes it easier to tear off paper strip. It is also
used for peel-off operation.
• The label-stop sensor (LSS) controls the paper feed and checks
for out-of-paper conditions.
• The printhead produces the heat that melts the "ink" on the
transfer ribbon or blackens the direct thermal paper in patterns
that make up the letters, graphics, or bar codes.
• The headlift mechanism presses the printhead against the ther-
mal paper or transfer ribbon, or lifts the printhead to allow paper
and ribbon load.
