OK, a couple of things... Some earlier Lexmark units had code on both a RIP board (raster image
processor) and an engine board. In this case, the code would have to be reloaded into both
boards. Fortunately, this can be done even if the printer will not boot to a ready state. However, if
this has already been done sucessfuly, the problem may well not be the printer but rather something
in the data stream. To confirm this, remove any and all data cables and reboot the printer. If it comes ready and you can print all the internal pages including the network config pages, then it is likely the
problem is the data stream. One must be careful when the printer is controlled by a print server
because the end user may not have control over the print que. If a corrupt or printer incomprehensible
job is stuck in the que, the printer will go to a 900 condition as soon as the network interface
initializes. This will continue until the print que is cleared.
Hope this helps...
