NOTE:
Regardless of printer model, if symptoms are similar to what you are seeing in this article, you can still follow the below preliminary troubleshooting steps.

What you will see

A 900.xx firmware error follows the connection of the printer to certain networks; these networks where identified to have transmission frames containing over 1500-byte packets, which exceeds the limit set by the IEEE 802.3 standard.

Troubleshooting

  1. Disconnect the printer from the network.

  2. Perform a Power- On Reset (POR).

  3. Perform a copy or print an internal test page.

  4. Clear ALL jobs from all print queues.

  5. Reconnect the printer to the network.

Does 900.xx return immediately? Then...
Yes Contact Lexmark Technical Support and provide article ID#:SO8684 to the support agent.
No Perform additional testing and attempt to answer the following:
  1. Does the error occur only when performing a print job?

If Yes, then identify the following:

  • the driver language, e.g., PS, PCL, XPS
  • the driver type, e.g., UPD, System Driver
  • the driver version number (#)
  • the exact print job
  • the software application used to generate the print file
  • the file type, e.g., .ps, docx, .pdf, .xls, .prn, .jpg, .gif...

If No... then identify the job type, e.g., copy, scan-to-function, or name of the solution software

  1. Is the printer's firmware-level current? See xref_HO550_xref for firmware update instructions.

See xref_HO3643_xref for further diagnosis and additional steps to be taken in the event of an escalation, which may be required to resolve this issue.
