If you have not already resolved this issue, we suggest you search our online knowledgebase for this product: WorkCentre 5735. I am not familiar with the Wyse C10LE NC but if you are trying to print PDFs please make sure you have the Print as Image chosen in Adobe. If you are printing from another program and getting the message make sure you have the correct paper loaded and the paper attributes set correctly to match the print job.
Alternatively, you can visit our Contact Us page for other support options.
Not been resolved, its only trying to print a test page from the NC so its not any document, its all done through the NCs firmware during the LPD setup of the printer.
I would recommend that you contact the support centre so they may assist with further troubleshooting. They can be reached at 1-800-821-2797.
We have experienced the same issue you're having. The work around we used was to share the printer from a Windows PC and then send the print jobs using SMB instead of LPD. I'd love to use LPD, but for whatever reason those jobs get deleted and not printed by the Xerox.
