Says tray 1 does not have paper but it does and it won't allow me to print anything

SOURCE: tray problems

There is a tray up sensor that has popped off. Its a black flag type piece that moves up and down with the paper stack.
Tray 1 can just be pulled out and up and it will pop right out.Look on the upper side of the frame above the paper stack for a sensor. You can compair to tray 2 as reference.

Hi,

You need to remove the trys affected, most likely there is a sensor issue.

Remove the trays and check behind them as paper sometimes falls behind blocking the sensors. If so, remove the paper.

Also, check the paper slides in the tray themselves, remove the paper and slide them in and out all the way, put the trays back in the machine and put the paper back in the tray moving the slides right up against the paper and close the door. It should work normally from now on, if not try a reboot one more time.

SOURCE: I can't get anything to print from tray 1, the manual feed. I'm trying to print envelopes and they keep printing on 8.5x11 paper from tray 2. If I put envelopes in tray 2 it won't print

Have you already tried this? After you click print and select your printer, click properites and select your paper from 8.5x11 to Envelope.

SOURCE: Printing from wrong tray

I suffered from the same problem for a long time. We got Xerox Phaser 8550 and 8560 here. I choose on computer "tray 2" but the printer just print from tray 1 which is empty.

Today i figured it out! It's some configuration at the printer. So go to "Paper tray setp" -> "Tray 1 mode" and "Tray 2 mode" -> change to "static".

I figure it's like this. Before it was "dynamic", it probably means the printer decides it's better to use tray 1 even though you choose tray 2 - and this decision is stupid. Changing it to "static" fixes this.

Let me know whether this works for you too!
