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".
