D K E L F M A G N B H O C I J Steady FK Load Media + Cartridges: Electronics Module Failure. Possible causes: D Fan faulty or badly connected. D Faulty ROM SIMM. D Faulty RAM SIMM. D Faulty Electronics Module. D K E L F M A G N B H O C I J Steady EM Align Media + Media: YĆaxis Shutdown. Possible causes: D Problems with the Cutter Assembly. D Clear any binding due to a media jam. D Turn the Printer off. Manually move the carriage along the carriage axis. Check for any areas where the carriage may be binding. D Ensure that the belt and belt pulley are in correct working order. Remove dirt from the pulley that could cause the belt to slip. D Perform the carriageĆaxis test and the servo/encoder test to check for problems with the carriage motor, encoder strip, and electronics module. D Remove dirt from the slider rod and chassis beam. Apply oil (Anderol 4068, HP part number: 6040Ć0858) to the carriage bushings. D At high temperatures, and if the fan is not working correctly, the internal resistance of the motor driver may increase, causing a decrease in the voltage between the motor contacts, and a shutdown of the motor. D Ensure that the encoder strip is not inverted, damaged or absent. D Reconnect or replace the trailing cable ' page 8Ć8. D Replace the carriage assembly ' page 8Ć37. D K E L F M A G N B H O C I J Steady DEM Ready + Align Media + Media: YĆaxis Movement Error. Possible causes: D Something is causing excessive friction in the YĆaxis (carriage axis).
