4.6.13 System software error service check
There are different types of 900.xx errors that can occur. There may be a communication problem (bad
cable, network connection, and so on) software issue, or a hardware problem with the controller board,
or ISP (internal solutions port). The communication and software aspects should be checked first.
Determine if the problem is constant or intermittent. Use the troubleshooting procedure below to isolate
the issue. Take any notes as instructed. You will need that information in the event you need to contact
your next level of support.

Those are RIP firmware errors.
Clear all print queues from print jobs.
Reboot the machine with network cable disconnected.
If problem repeat after connecting network do restore factory default from the Configuration Menu.
If anything works for you may have to replace controller board...I personally would blame poor Lexmark design and throw it in the bin.

On 4050 the problem is the ADF.

When the machine is starting you listen the ADF testing the pickup arm ?

Everytime I had 900.x errors on Lexmarks it was a corrupted print job (mainly stuff printed direct from Explorer/Edge) or bad driver. Follow tsbservice guide, clear print queues for any stuck jobs, reinstall print driver and maybe a FW update if it's possible.
