Take a moment and make sure that you are calling for paper from the correct paper source.

Why does my printer say there is no paper in the tray when it is full?

from what u did I would look for a broken paper sensor.
It could also be a ripped paper hanging the sw.
it might also be that somehow the operating tray got changed in the config - if u have multiple trays or manual feed

No paper in tray light on all time

There is a plastic arm that rests on your paper. As the paper supply decreases, this arm drops lower and lower. When you are out of paper, the other end of the arm trips a photo sensor that tells the printer "you are out of paper." The sensor is either jammed or broken. Pull the tray out and examine the printer for the paper sensor.

"Print Mechanism"


When the paper is picked up by the pickup roller the paper crosses a sensor that tells the machine that the paper has fed from the tray. The sensor is an infra-red light emitting diode and an infra-red receiver placed in a small plastic "U" shaped body so that the light emitting diode and the receiver are looking at each other. It is located in the throat of the paper path (where the paper first enters the machine from the tray. A plastic "tab" (sensor flag) sticks up in the "U" to tell the machine that there is no paper in the path. When the paper was pulled out from the front of the machine, the "tab" (sensor flag) was either displaced from the sensor body (U) or it was broken off by the paper, so now the light emitting diode can be "seen" by the receiver and the machine thinks that there is paper in the paper path. If you know someone who is mechanically inclined,k they can remove the cover from the machine and either reposition the sensor flag into the sensor body, or if it is broken off, glue the sensor flag back together.

Good Luck

The following is my exact problem...can it be repaired? Hard to tell if piece is broken. "My faxes are not printing. The error message says there is a paper mismatch and tells me to remove the transparency...

Somewhere, your printer has a sensor (probably a light and a mirror and a detector), to try to distinguish between transparency media and opaque media (such as a sheet of paper).

So, that sensor either has a piece of transparency media stuck inside it, or it is otherwise misdiagnosing what media is between the light-emitter and the light-detector, and thus is claiming that there is transparency media loaded into the paper-tray.

It sounds like you need to take the printer to a qualified technician.

My paper loader wont accept paper that is to say paper is no log

What I understand the paper tray is installed correctly.
Some machines have push sensors inside the at the end of the tray. Look inside the area where the tray goes in with a flashlight. Everything is mostly black so it is hard to see.
Look for actuators that need to be pressed. Locate the tray end area to see if there is a plunger that pushes in the switch actuator. Sometimes the plunger is missing on the tray, or the slide selector on the tray is not positioned correctly. I cannot see this tray so look for these common areas.
Sometimes you can gently move actuators up and down, and phsyicaly see if they fell out of postion or just completely broken.
Also, paper dust is common in these areas. If the sensor is dusty, the sensors will tell the machine there is a jam, if you can clean the sensors from debris even excessive tonor or developer that falls in these places a lot.
Good luck.

Dell 3000cn keep getting load mpf when i try to print but there is paper in the tray. how do I get it to recognize the paper. I've changed nothing on the computer but this just started to happen! please...

I have a Dell 3010n myself, and a few times I did run into that "Load MPF" issue.
1.) Before printing a document, please check and see the properties. i.e. Kind/type of paper, which tray, or if printing envelopes or any other document than a regular 8 x11 paper. Putting all the tray and paper type selection on "Auto" can be very helpful.
2.) On the printer itself, there is a menu button where you can configure the type of paper, i.e. regular 20 llb. copy/print paper, glossy photopaper, thicker paper - after you place a fresh load on the paper tray and slide it in, usually it will ask you which type of paper you just loaded. Make sure it is the same settings as the document that you are trying to print: i.e. if document settings on computer was set to print on photopaper and you have regular paper on the tray, the printer will do a "Load MPF".
The paper sensor on it is amazingly (for a Dell, that is) sensitive and it can differentiate across a lot of paper types/thickness. If you have several computers and user across a network, and there are several paper-type settings done on the printer itself, this "Load MPF" issue will present itself more often.
In my case, it's simply because the person who recently changed the paper-type to glossy cover paper from some user who previously printed to a transparency forgot to revert MPF/Tray 1 to regular copy/print paper. Most cases, the printer setting on the PC has been left to print on to a transparency by default, so even if I stack the tray with copy paper to the hilt, it still will do "Load MPF".

Laser printer does not print

Hi there it may just be that the paper tray springs are not pushing the paper higher enough not making contact with the paper detect sensor arm. Or the sensor arm is broken and will need replacing. Check the tray springs also check the sensor arm you will see it if you remove the cassette and look inside there will be a black plastic lever hanging down when you put paper in this lever should go up as the paper acts as a barrier thus telling the machine that there is paper in it.
