Service tertiary error codes
Service error codes are generally non-recoverable except in an intermittent
condition when you can POR (power-on reset) the printer to temporarily
recover from the error.
Note: All service errors are initially communicated by all lights flashing
which is the primary indication or code. For brevity, this indication is
not repeated in the following codes.
Controller software
Controller software error/illegal trap (90x). For the other errors, which
indicate a faulty programming process or faulty component on the controller
card, replace the controller card. See
page 4-15.
