What Can I do when a System Error Code Appears on the FrontĆPanel Display? Chapter 2 contains a list of system error codes and their respective descriptions and recommended corrective actions. Only try one recommended action at a time and check if the error code has disappeared. If you have an error code which is not documented in this Service Manual or you have an error which you cannot resolve, then report the error to the HP Response Center or the nearest HP Support Office.

If the Line Sensor test fails, to resolve the problem, try one of the following: 1 Line sensor incorrectly calibrated: The accuracy calibration includes calibration of the line sensor on the carriage. You must use HP Matte film when performing the accuracy calibration (Details Chapter 5). Otherwise the line sensor will have problems loading some types of media. 2 Check and if necessary replace the Trailing Cable page 8Ć8. 3 Replace the Carriage Assembly page 8Ć37.
