About Servicing the Embosser Module
The embosser module presses characters into card stock by squeezing the card between a raised metal
letter, called a
punch
, and an indented letter of the same shape, called a
die
, installed on the embosser’s
top and bottom embosser wheels. For indented characters, the die is replaced with a flat metal plate so
the card stock is only altered on the character side. Worn out punches or dies can produce characters of
poor quality, or characters that are raised/indented less than the required depth.
The top and bottom embosser motors each drive a
hammer
that applies force to the punches and dies on
the embosser wheel. Both hammers have a small round plate with a hole that lines up with a cone on each
character. The cone on each character should be sharp and unbent, and must line up properly with the
hole in the hammer.
shows a magnified view of a properly aligned hammer (above) and die
(below), viewed from the front of the embosser. Because it can be difficult to see the front of the
embosser module with EC2000’s cover and other modules installed, it is best to inspect the cones with an
inspection mirror. Section
