slide them into position. Ensure the cables are in their proper channels and are not binding the printhead. Note • When mounting the printhead fork assembly onto the print mechanism, visually

inspect and ensure the cables are in their channels at the back of their carrier assembly, power cable under data cable, and are not binding on the print mechanism. 4. See Figure 17. Tip the printhead fork assembly slightly and insert the printhead ribbon

guide into the print mechanism as shown. 5. Tip the printhead fork assembly up and into the print mechamism ensuing that the two

locating protrusions on either side of the print printhead snap into the locating holes of the ribbon guide plate. Move the assembly back and forth to be sure that it is engaged. There should be little movement. 6. While holding the printhead in place, install the thumb screw to secure the fork assembly.
