I get remove paper standard tray on a AFICIO AP3800C and it locks up the software. Then does not allow clearing the message. I have removed paper. Tried Aux feed. Always does same thing

There's a video here:

Can you put the old fuser back, just to see if the message clears.

Sounds like it is misfeeding from the Default tray (just not getting the paper into the machine). try removing the paper from the default tray, and use another one. If it works, then the paper feed rollers are the likely cause.

Check the little black piece of plastic that senses the printed page exiting the machine. Our sensor was stuck and I was getting the same message (an similar Ricoh product). When I gently reset the black piece to center, moving freely, printing worked again. I think the sensor got jammed up when we were trying to remove a bad paper misfeed.

Ricoh manuals very confusing on this error message. They refer to standard tray, tray one, etc. without being clear whether it's a paper feed tray or the so-called "standard OUTPUT tray." The output is not really a tray, it's just the depression where your sheet lands after printing. I wrenched on the paper feed trays and their settings for an hour before I figured out they meant OUTPUT.

You should just be able to place paper on the tray and then select the bypass tray under "properties", "Paper", then under "tray" select "bypass tray" when printing.

It may be something to do with the paper size settings on printer driver, document print settings or page setup. If for example the computer thinks the paper size is Letter, and the paper in Tray 1/2/3 is A4, it won't print.

'Standard tray full, remove paper' is the output tray where the prints exit.
Check also the exit sensor/feeler condition.

Good luck and please rate me, thanks.

it may be one of two problem, to start off with try using one of the other trays or the manual feed. to see if it's just that tray or the machine. you may need to cancel all jobs in the printer before starting and also keep the main tray open. let me know what heppens.

Thank You,

When that message is displayed, the printer thinks the output tray is full of paper and it won't print any more because there is no room left to spit pages out. If the output tray isn't full of paper, the sensor that detects paper there might just be dirty or dusty.

That sensor is a black sensor that should be located just at the point where the paper exits the machine, above where the paper comes out. Blow some compressed air on the sensor to try to clean it off and see if that clears your error message.
