Two possibilities I can provide:

1. The fuser pressure roller is out of round and the noise is the flat spot hitting the hot roller on every rotation.

2. These printers have an envelope mode that activates a solenoid in the fuser when printing envelopes to force air out of an envelope.

If it makes the noise constantly then it is the fuser. If only as the page is exiting then it is the envelope mode.

You need to be sure that you have added the duplex unit and tray unit in the windows driver. The "device" tab will allow you to add the duplex and tray to the printer.Also there is a self-docking connector on the bottom of the printer that connects to a similar connector on the duplex unit. Check that these connectors are not damaged by lifting the printer off the duplexer and inspecting visually . You can try removing the duplex unit altogether and just install tray 2 below the printer with no duplex unit at all to see if the printer sees tray 2. If it does see it then the problem is in the duplex unit. If the printer can't see the duplexer it also wont see tray 2 which is below it. Simply re-plugging the units might fix it too so give that a try.

Please get back to us if you have further query or else please accept the solution.

The printer tells you to insert a letter format paper in the mp (multi purpose) feeder (the manual tray).
If you press the GO key the print probably proceeds with print job (if has the paper loaded in mp feeder)

They are all different. Look on the bottom of your printer, on the back, or inside panel covers.

If you are having trouble printing a picture of something with your Lexmark Laser Printer, while it prints text fine, it may be a memory issue. In the 'old days' Laser printers required their own RAM to be upgraded for fancy printing, today many of these problems are solving be 'sharing' RAM from the PC. Ensure you are not running many programs and have available RAM or virtual RAM on your computer (after a reboot for example) and try printing again.

I hope that helps.

I have to ask this question of you, just to make sure this is not an issue. Are you using a factory new ink or toner cartridge?
Please consider the following:
If you are using a refilled or third party cartridges that may well be your problem. Most manufacturers build logic into their products to prevent the use of “Other Equipment Manufactured” cartridges as well as re-filled cartridges.
They do this to prevent problems from contaminated inks or toner causing problems with print quality or damaging the physical printhead or photo conductors.
If you are using factory new ink or toner cartridges, then please call the manufacturer’s Technical Support for assistance with the warranty on the cartridges

this is caused by the flag on the output bin being stuck in the up position. located where the paper comes out the top on the left side

Lexmark T634... | Answered on Dec 07, 2009

What your printer is telling you is that it thinks or knows that the top exit tray for the paper is full. This is the tray that is moulded into the top of the printer.

This caused by two things. It is actually full or the Bin Full Actuator is out of position and forcing the error condition.

Look at the standard bin. Over to the top at the top left corner there should be finger (almost the same as paper clip) hanging down. If it is not there, then it is more then likely that the finger is jammed up.
