Re: Lexmark X422- error: "942 service scanner failure

According to Lexmark,one or both of the CCD lamps in the scanner have failed, or the CCD cable is loose or bad.

Re: Lexmark X422- error: "942 service scanner failure

If the Lexmark X422 Printer gets an error code 944 or 942, nine times out of ten it means that the mirror and two glass lenses in the scanner mirror assembly need to be cleaned (even though in the repair manual it says that it means that the lamps or ccd cable need to be replaced).

Since you have to perform the procedures below to replace the lamps or ccd cable anyway, you might as well try to clean the mirror and two glass lenses first (before you go through the expense of buying new scanner lamps) since it won't cost you anything to see if cleaning the mirror and lenses resolves the 942 or 944 error code.

First, turn off the printer.

Then, unplug the printer from the power outlet.

Now, remove the document tray from the back of the scanner bed by gently pushing in the two plastic sides of the document tray inwards towards each other.

Now loosen the front panel by using a very small flat head screw driver to move the clips in the clip holes under the front panel. This will allow you to lift up the front of the front control panel.

Then, open the document feeder by pressing the gray button. Then, look for the arrows inside the document feeder which indicate where to use a screw driver to push the plastic clips in to remove the side covers of the document panel.

Then, remove the two Phillips head screws from each side of the document feeder.

Now, you should be able to pull the front control panel forward slightly so you can lift it up slightly....exposing the three plastic clips that hold the back of the front control panel to the scanner bed.

Push in the three clips to release the back of the control panel from the scanner bed. Now, the front and back of the control panel should be released.

Now, there are three medium sized Phillips screws that are securing the back side of the scanner bed. The screws are in three deep dark holes (in the plastic frame of the scanner bed) that are on the top of the back of the scanner bed, where the document tray was attached.

Now, remove the three Phillips screws with a medium sized Phillips screw driver. You need to stand above the scanner and have a head lamp so you can see the screws in the dark holes so you don't strip the screw heads. Unscrew the three screws and leave them in their holes.

Now, you should be able to carefully lift up the scanner glass bed with plastic frame and document feeder and rest it against the wall.

Now, remove the two black screws from the top of the black plastic mirror container. Lift the front of the black plastic mirror container (it should easily pivot up because it is made to slide on the silver metal scanner rod and move) and disconnect the white connector that powers the scanner lamps.

Now, gently lower the mirror assembly container and remove the black plastic lid from the mirror container, exposing the mirror and top glass slide. Clean the mirror and glass slide with lens cleaner (lens cleaner for camera lenses or for eye glasses will work) on a soft lint free cotton a clean cotton t-shirt. Do not use Isopropyl Alcohol because it will leave a blurry film on the mirror and lenses.

Now, gently raise the mirror container again and clean the bottom glass lens as well, in the same manner.

Now, reattach the white power connector for the scanner lamps.

Now, make sure the white scanner lamp wires are fed into the mirror container properly so they are not being pinched by the cover and so they are not blocking the mirror.

Screw the two black screws back into the mirror assembly cover to secure the mirror container. Lower the mirror container assembly.

You can also clean the underside of the glass scanner bed at this time.

Then, reassemble everything by doing everything above in reverse.

Can you change the fax speed on the Lexmark X422 mfp

Why would you want to change it?
When one FAX connects to another FAX, they "negotiate" the speed and capabilities, so as to guarantee a successful data-transfer.

As they negotiate, you may hear the "squawking" soon after the other FAX picks-up the call.

usually it means that a sensor in your fuser is bad. If you have a P.M. Kit replaced the fuser and clean the printer.

but before you do, make sure that you have cleared all jams, including in the fuser.

Its probably time for a Preventive Maintanence
