That is caused 99 percent of the time by the fuser.

There is a solid aluminum roll and a silicon rubber ( pressure) roller in the fuser. The pressure roller either developes some flat spots from park ( non running) time and over time heat and use cause it to deform and become out of round. What then happens is when the paper enters the fuser it does so with a slight twist, and the pressure of the fuser, for lack of a better term,Irons in that crease during the fusing process.

Gave the explaination so you would understand what is happening.

There is a tiny little magnet that falls off and/or has reportedly been put on backwards (fell off is what happened to me) on the auger assembly. It's nearthe black auger chute on the end of a shaft. It's tiny--a little bigger than a grain of rice. I had to replace the auger shaft assembly but if you can find the magnet, you can super glue it back on.

Phaser 7400 LCD is blank. How can that be fixed?

Once the LCD is gone blank that means you have to change the control panel. it's not difficult to change, all you have to do is remove the covers that are behind the the control panel. Once you have removed the white covers you can now unscrew the metal hinges. Then you have to insert a flat head in the small cracks behind the control panel that opens the control pane blue covers. Now you disconnect the data cable that connects from thecontrol panel to the machine and that's it. Hope this helps
