You have to set up the settings in user tools on the operation panel.

This problem is referred to as color to color alignment. Most color laser systems have a rough adjustment by means of a screw somewhere and a fine adjustment that is done in diagnostic mode as part of a setup routine. Try the latter first by locating your manual and looking through the troubleshooting guide which should explain how to force the machine to do an automatic color alignment. Your manual should be available online from your manufacturer's web site if you can't locate it. If this doesn't work you will need to take it in for servicing unless you are handy with tools and can find a service guide for your model.

They have a universal PLC-6 printer driver. Maybe the same one as above.

I have the same streaks problem. Any solutions?

You should see a bypass tray near the main paper tray. On laniers it is recommended you use the bypass tray for envelopes.

when you send a print job make sure to select the bypass paper tray option

Fusing fan motor error.

If when you open the rt. door are the streaks on the drum unit? If not remove the 1 screw and slide the fuser out and check there
