900.00–900.99 (except for 900.05)—System software error 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 support.
Note: Before troubleshooting, determine the operating system used when the error occurred. If possible
determine whether a PostScript or PCL file was sent to the device when the error occurred. Ask the customer
which Lexmark Solutions applications are installed on the device.
