Error LED On Steady 34 Steady 38 Error + Film: From firmware revision A.01.04 onwards, this combination of LEDs indicates an error in the EEROM. See Steady 135. Error + Normal: Not enough memory to allocate internal data structures. D Turn the plotter off, and then on again to see if the problem disappears. D If the problem remains, consult recent service notes for a possible solution. D If no service note deals with this error, report the problem to your HP Response Center. Note conditions and actions before error occurred. Include setup sheet and service configuration plot in report. Paper + Cartridges + Error: Processor fault. Replace the electronics module. Steady 123 Steady 135 Steady 136 Paper + Error + Fast: Error detected in the EEROM. The possible causes could be: D Power failure during the tests. D Faulty carriage PCA.
