This means there is a problem with the engine board. You can try to reset to factury defolds. Turn off the printer, push the buttons 2,3 and 5 and than turn on the printer. When message "reset to defolds" apears release the buttons. If this does not work than you have to exchange the engineboard.
Good luck, Gerrit Jan

a 900 rip error is the engine card. located behind the system board (formatter) if you can get the printer to a ready state you can phone 1800lexmark and get a pin code from them costs about 15 bucks. if this flash does not work you will likley need a new engine card.

If the 900 error occurs
only when the printer is receiving information from a network or
computer, contact your software/network support. If the error occurs
when the printer is idle or not connected to the network or PC, there
may be a printer hardware or connection problem. Sometimes a bad
connection with an Internal Network Adapter/Network Card can cause the
problem. The first thing to check is the base printer.
check the base printer:
Optra S series and Optra K series printers: Continue to press Menu > until you see TESTS MENU.
Optra T and Lexmark T and W series printers: Continue to press Menu > until you see UTILITIES MENU.
