8. While pushing the encoder strip spring toward the carriage, hook the left end of the encoder strip onto
the flange on the left end of the carriage bar (see Figure 6.12.6b above).

Preparation
Follow the appropriate printer disassembly procedures for removing printer housings and accessing the
print bar.
Replacement Note:
When removing the encoder strip, note the normal location of the encoder strip as it must feed through
the optical encoder located on the back of the carriage. The encoder strip should be replaced if the strip
is damaged (badly scratched or torn), or contaminated with ink which can cause erratic print operation.
Removal
1. Move the carriage to the center of the carriage path. This may require rotating the bottom gear on the
service station to release the carriage lock.
2. Press the encoder strip spring (on the right end of the carriage bar) toward the carriage.
3. Lift the encoder strip off of the flange at the left end of the carriage bar, and then lift it free from the
flange on the spring (right end).
4. Pull the encoder strip out of the carriage assembly.
Replacement
1. Move the carriage near the right end of the carriage path, so that the right pulley is visible.
2. Insert either end of the encoder strip through the encoder strip spring and in front of the pulley.
3. Guide the end of the strip below the curved flex circuit, and into the back of the carriage (see Figure
6.12.9).

4. Feed the strip through the encoder on the rear of the carriage.
Note:
If the encoder strip is installed correctly, the encoder strip will NOT make any contact with the car-
riage assembly or flex cable. If the encoder strip touches any other component, it is installed incor-
rectly and must be removed and reinstalled again.
5. Pull the encoder strip to the left, and hook the right end onto the encoder spring.
6. While pushing the encoder spring toward the carriage, hook the left end of the encoder strip onto the
flange on the left end of the carriage bar.
7. Slide the carriage along the carriage path to verify smooth movement without resistance. Leave the
carriage in the service station position (left side of print bar).
8. Ensure that the encoder strip is clean.
