REPLACEMENT
1. Push the moving blade of the cutter down to its bottom position.
2. Install the presenter module in the reverse order. See page 40 for correct connector
positions.
3. Check that there is a 0.2-0.5 mm distance at any point between the rear edge of the
presenter module and the cutting knife. If necessary, adjust by loosening the fixing
screws of the print and cutter module assembly. A too big distance might cause the
paper running down between the cutter and presenter modules. See Figure 8.

CAUTION!
The printhead is sensitive to ESD (electrostatic discharges). Observe all the usual
precautions such as keeping the printhead in a protective “ESD-bag” until you are ready to
install the printhead. Do not touch its connector pins. Use a grounded wrist strap when
handling ESD-sensitive components.
