To remove the cutter assembly, refer to Figure 6-23 and perform the following steps:
1. Remove the right endcover.
2. Using a 5.5 mm nut driver, remove the nut and washer that hold the right end of the

spring-bracket.
4. Using a TORX T-15 screwdriver, remove the encoder spring bracket.
Note
The cutter carriage preload arms are spring-loaded. Hold the cutter wheels
toward the center of the cutter carriage assembly while performing step 5.
5. Holding the cutter wheels in toward the center of the cutter carriage assembly, move
the cutter assembly to the right and off of the front slider bar.
6. Slowly release the wheels to relax the spring tension on the wheel arms and lift the
cutter assembly clear of the plotter.
To install the cutter assembly, do the following:
1. Rotate the wheel preload arms against the spring tension to the center of the cutter
carriage and hold them in position while performing the next step.
2. Move the cutter assembly’s lower wheels onto the overdrive support assembly.
3. Slide the cutter assembly along the overdrive support assembly and guide the upper
wheels into the starguard groove.
4. Guide the cutter blade in front of the linear blade. See Figure 6-23.
5. Slide the bushing into the cutter assembly and move the cutter so that the bushing
slides onto the front slider rod.

7. Verify the cutter assembly pick-up function works by sliding the pen carriage into
the cutter assembly so that the pen carriage will engage the cutter assembly.
