CS board assembly can be removed without removing the CR from the printer
mechanism. In case you omit Step 2 (CR removal), note the followings:
• •
When removing the CS board assembly, note the direction in which the cutout
part of the cam faces. Set the cam as shown in Figure 3-31 so that it is not
damaged by the photo-coupler in the CS board assembly.
• •
Inside the ribbon cartridge holder, there is a gear train used for ribbon feed and
color shift. Since the gears in the gear train tend to disengage easily, do not
touch the gear train when removing the ribbon cartridge holder.

When installing the ribbon cartridge holder, set the CS cam with the cutout side
facing to the sensor.
