The only way to resolve the issue is login to your printer by using any web brower and printer's IP address.
Go to Job tab and delete the pending print jobs.
Now on your computer go to printer properties and select preference, from trey selection, Select trey 1 from the list and then save and exit.
Now print and it will be working fine.
I am having this exact issue on my 6515. It used to work fine but now won't accept that the paper loaded is A4 plain white which it is.
I have removed and reinstalled the drivers but the issue is the same.
I am now unable to print.
What I have found is that occasionally, for some reason the PC (Win 10) is sending the wrong info to the printer re paper size. The printer won't simply over ride this and print with the (A4) stock that is loaded, which is unfortunate.
Even when you turn the printer off and on and job stays in it.
You can delete the job from the printer through its menus. Once doing that the printer will work again.
When printing docs I am checking very carefully that on the PC I have selected A4 paper size and if the problem recurrs I will se if it is only from Word or from PDFs opened in Edge etc. I suspect it may be an error with one application.
But it is a pity the Xerox can't bypass this anyway and use the stock that is loaded.
I got this far with amazing help and advice from a company called Printerland.
Not acceptable at all! I'm at win10 21H2, I can't roll back, post secondary institution.. This is a xerox issue and should be resolved by them. It's global from what I can see in my searches.
I'll update you if I get any headway! Tks.
I rolled back my version of Windows, uninstalled the drivers and rebooted the machine. I then reinstalled the drivers and the problem went away. God knows what's going to happen when I'm forced to go to the next version of windows. My solution isn't ideal a Xerox should resolve for all for free, not charging for an Engineer!
Please call them back to follow up or ask for a supervisor to get the quote.
