If this error code appeared but was NOT caused by a paper jam, then try the following:
1. Too much friction in the Slider Rod. Enter the Printer Informationutility and check the Scan-Axis usage. If the percentage is close to 100%, then lubricate the Slider Rod.
2. The Carriage is bumping into the Service Station. If the carriage is stuck at the right hand side of the Printer and cannot be moved out to the center of the Print Platen it is because the Service Station cannot uncap the Printheads. In this case replace the Service Station/Aerosol Fan Assembly.
3. Perform the Carriage Movement test.
