OK found the setting now its under Services / printing / general. I only brought this ( paper mismatch problem) up in this thread as the bypass error was the only one showing and it acts as a red herring to the actual problem when not printing.
Yes its crazy. For a while I though the switch on the bypass tray door was faulty until I realised there is no switch showing the door closed! Good idea about the sachet, but I found a pen or pencil of the right diameter works, I thought the sugar could get messy if it absorbed too much water, and would make a real mess if dragged into the printer if you accidentally request print from the bypass tray ( since it now thinks there really is paper in the bypass tray). I did also try the solution to switch bypass tray to bypass not static but that did not work for me. I also found sometimes it just will not print if you try to print the wrong size and you only have A4 paper in the tray, but I found a setting in somewhere in workcenter to turn that off and ignore the size setting from the print stream, I can't find it again though!
There are some morons working at Xerox, and I wouldn't be afraid to tell them in person.
My solution is this:
1. I put a sugar sachet there :), but you can also use adhesive tape to seal the black element, the position of which I marked in the photo with a red oval (in the next post, because something this forum is going crazy).
2. Close the front tray and that's it. As a result, you cannot see that the tray is there. :)
3. The result: brainless work at Xerox.
This "error" message haunts me every day of my working life. I have users who are doctors and when they see a red notification box pop up every time they print, they call me...which is every day. Stop the madness, Xerox.
>> the programmers just program what they want with complete disregard for any proper flow logic at all.
These same programmers worked on the Xerox VersaLink. Utter garbage software that causes never ending confusion and frustration. Our users HATE them.
What absolutely ridiculous thinking ..... System printing to tray 1 and a warning message comes up for the Bypass tray ..... And this is with the Bypass tray closed which should mark it disabled ..... Did anyone think about how many support calls a tech will get because the users are seeing a red "X" and think something is wrong? ..... Who thought this one up? Sounds like a person who has no business doing any sort flow decisions at all ..... As time goes on, the programmers just program what they want with complete disregard for any proper flow logic at all.
