The Printer has detected a leak in the Tubes System – Should ONLY appear in printers with the Ink Leak Detector installed.
Try the following:
1. Check for ink in the Ink Leak Detector and, if present, replace the complete Tubes System.
2. The Ink Leak Detector could have been triggered due to condensation in the Printer. Power OFF the Printer and allow the Printer to dry for 15 minutes. Power ON and check if the System Error Code has disappeared.
3. Replace the ISS PCA.
Only replace one component at a time and check if the error has gone before replacing another component. Using this procedure you will be able to determine exactly which component failed.
