Lexmark MX910de, from power outages, the printer displays 919,224. Invalid Engine Code. Help me please.
Lexmark Error Code 919 when a 3000-sheet High capacity tray is installed. The 919 error removal is possibly caused by a bent pin or loose connection between the 3000-sheet option to the 2500-sheet or the 2x500-sheet tray options.
Step 1: First You need to make sure the packaging materials used in the option tray are all removed, especially if the error appeared only after installing the 3000-sheet High capacity tray.
Step 2: You need to make sure that the cable are properly connected to the engine controller board and controller board.
Step 3: If the option tray is cleared of any packaging materials, then you need to inspect the connectors on both the 3000-sheet High Capacity tray and the 2500-sheet or 2x500-sheet tray options.
