6) If any cones are broken or bent, replace the characters in the same location if possible. If replacement
is not feasible, cut off the top and bottom tines using diagonal side cutters, remove the top and bottom
characters from the tines, install them to another pair of tines, and re-map the character to the new
position after preventive maintenance is complete and the device is powered on (see section
5.22
How to Remove / Re-install Embosser Fonts and section 2.9.4 How to Use the Character
Mapping Page ).
7) Check the embosser wheel alignment by standing in front of the device and looking straight down at
the embosser. Use an inspection mirror as shown in
Figure 4-3 so you can see the cone on the
bottom of the current character and the hole in the embosser hammer. Figure 4-3 shows a cone and
hole that are not properly aligned.
8) Check embossed character heights using the steps in section 6.6 How to Calibrate the Embosser ,
and adjust them if necessary to account for normal wear. Pay special attention to any characters you
have replaced or re-mapped.
9) Note the position of the top and bottom knuckles in case they move during the following steps.
10) Add 2 drops of Teflon lubricant to the left and right sides of the shaft that holds the top embosser
knuckle, between the sides of the knuckle and the rocker arm.
