3. Insert the ribbon cables fully and squarely into the ZIF connectors. Caution Ensure that the flex cables are inserted into the ZIF connectors on the printhead fully and squarely. If the cables are inserted incorrectly, they can short out the Wave Amp. 4. Connect the data cable connector and heater harness connector. Caution The printhead heater cable not only needs to be routed through the cable restraint, but also needs to be clear of the printhead to prevent interference which would result in errors 7009 and 4025 fault codes. Caution Before reinstalling the printhead, move the wiper all the way down. 5. Lower the printhead into its mounts. The printhead should be tilted forward in the print position. 6. Route the air hose through the frame and connect it to the purge pump. 7. Install the Roll Block on the left end of the printhead Shaft. The Roll Block must be oriented as shown on the paper label on the left side of the printer frame. Caution Ensure that the printhead restraint does not obstruct the Roll Block. 8. Install the left and right printhead restraints. Caution Ensure that the tilt spring on the left restraint is properly positioned in the notch on the back of the printhead and does not pinch the air hose. 9. Set the X-axis bias hook and spring on the end of the left printhead shaft. Ensure that the point of the hook is centered in the shaft and the rest of the hook floats freely. 10. After completing the installation, print the Light Stripes Page and check for jets in service mode. If necessary, use the control panel to reset the jet substitution mode. 8-22 WorkCentre C2424 Service Manual
