System Error: Steady EKL 8 After replacing a new electronics module it must be configured either as a DesignJet 430 450C or 455CA If a new module does not show this error it means that it has been installed previously and was probably calibrated with other parameters After configuring the module Error code Steady DLM will appear which means the accuracy calibration must be done After the accuracy calibration is done all other calibrations must be done If configuring the module does not remove the error even after switching the Printer OFF and ON then the EEROM in the main PCA is probably defective Before trying to replace the electronics module try clearing the EEROM and perform all the calibrations again and see if that solves the problem
System Error: Steady EK 8 Switch the Printer OFF and ON again and see if the error remains If the error appears continuously replace the Electronics Module The Calibrations in the EEROM have been lost Perform the Accuracy Calibration
