Troubleshooting Trailing Cable connection, so just reconnect the Trailing Cable again to double-check that the Printer now works. If, after reconnecting the cable, the error appears again, either the Carriage PCA or the Trailing Cable is defective. In this case, first try replacing the Trailing Cable and then the Carriage Assembly. n If the Printer did not initialize correctly, even after removing the Trailing Cable, the problem is either in the Main PCA or the ISS PCA. So, once again, to isolate the failure, disconnect first the ISS cable and check whether the Printer works. If it does, reconnect the cable again to verify the failure and then, if necessary, replace either the ISS cable or the ISS PCA. n If the Printer still does not initialize, even after removing the Trailing Cable and the ISS cable, replace the Main PCA. 1-18 HP DesignJet 5000 Series Printers Service Manual
