Cannot insert the tray all the way - Jura Capresso Impressa F9 Espresso Machine

If you cannot insert the drip tray as you have said above then the machine needs for you to find a way to insert the tray then the message should go. If the tray has an extra bucket on it for spent grounds then try removing that and just fitting the tray alone.

Cycle power on the Printer.

1. Turn the printer off.
2. Wait 10 seconds.
3. Turn the printer on.
4. Determine if the issue still occurs.

If tray 1 is being used:

1. Remove and reseat the tray.
   To remove and reseat the tray, perform the following steps:
   1. Pull the 250-sheet tray out of the printer until it stops.
      
   2. Hold the tray with both hands, lift the front slightly, and remove it from the printer (Figure 1).

Re-insert the paper tray into the printer and push it until it stops (Figure 2).

You sent a paper size different of the requested by the printer. Just load the requested size or delete the spool.
Some PDF downloaded from internet has A4 or 8,5x11", maybe is requesting one of this sizes.

If you can not delete this message, delete the spool using the printer manual in the control panel of the printer.

Dell 3100cn Color Laser Printer Error 024-965 - Load Tray 1

Cause:
The "Paper Tray Inserted" sensor buttons are not being depressed by the Paper Tray so the Printer thinks no Tray is inserted even if the Tray is properly inserted.

If you pull out the paper tray and look at the Paper Tray opening, you will see three white vertical sensor buttons along the left-hand side at the mouth of the aperture where the paper tray slides in. These three white vertically aligned push button sensors tell the printer that the Paper Tray is inserted when the paper Tray is
properly pushed all the way in and aligned. It also signals to the printer by noting which button is depressed whether the tray is a Letter Size or Legal Size tray that has been inserted. These buttons which are fully visible as soon as the tray is slid out can move out of place and even fall into the wall of the Tray slot preventing the buttons from sensing the tray.

Solution:
Click it back into place. There should be no play and the buttons themselves should be the only thing that move and then only in an in and out manner. They should move out toward you when the Tray is removed and be pushed in when the tray in slid into the paper tray feedering slot. A pair of needle-nose pliers may be necessary to draw the button module out of the tray slot wall if it has fallen in. Once it is STIFFLY repositioned and the Paper Tray reinserted, reset the printer by opening and quickly reshutting the printer cartridge compartment. This action will recalibrate the printer, shut off the amber error light and resume the current printing job if one was in progress.

Good luck!

With the R800, you must slightly open the paper feed panel door, lift it vertically about an inch and then lay it open horizontally away from the printer. Without doing this, there is no way to insert the disc tray.

Check the right side of the tray holder. There should be a small lever (micro-switch) that you can feel and press in. If it does not click when pressed then you need to replace it at a service center. If the leaver just broke off (a small triangle piece with a tab on the end) then you may be able to stick a piece of card board to make the switch click and fool the machine to think the tray is in. until you can get it to a service center.

if this unit is a bit older, than it's possible that the sensor switch is stuck

Look for a small pin hole in the front of the DVD player. Insert a pin into the hole to open the tray.
Also try right clicking the DVD icon, click 'eject', then insert the pin into the hole.
If the door only opens partially, grab it and pull it open. Then insert a blank DVD into the tray, then see if the tray will open automatically with the disk in the tray. If so, then keep a DVD in the tray at all times.

This can be a messy and frustrating problem to fix. You have to insure that the gears which control the opening and closing of the disc tray are correctly aligned with the apparatus inside. I have fixed this successfully on my own, but I must say it wasn't easy and involves removing the cover to give you better access, taking the tray out again and fiddling with it until everything is lined up properly. Might be worth sending for repairs.

There's a little plastice lever type thing that hangs down above where the paper tray is inserted. When the paper tray pops up after being inserted, the paper moves this lever up. This is how the printer knows if there is paper or not. With the tray out, push the little white lever up and see if the "No Paper" message goes away. If it does go away, the lever/sensor is working OK, if not the lever sensor is bad. If that was not the problem, check that the paper tray is popping up after being inserted (look from the back of the device while you insert the tray). If it does not pop up, there is a little white plastic button type thingy on the side of the tray that releases the paper tray to pop up after you insert it into the printer. Make sure that is working correctly. If you flip the pritner upside down, you can see this little white plastic button type thing that should release the paper tray to pop up during the insertion process.
