Hi I'm sorry to hear that.
How old is your printer?
Also have you reset the printer once you replaced the paper?
And were there any power outages or storms in your area just prior to this event?
Hi thank you for that information.
This issue has to do with the machine sensing the paper and tray.
Make sure the tray seats fully and correctly and ofcouse has paper lol.
Then turn off the machine and unplug its power cord wait 5 full minutes then plug the printer back in and turn it on. Please let me know if the unit functions or you still have the same issue and error message?
If it clear the error great then please rate kindly. But if not do not rate yet but simply reply to me for more information.
