Lexmark T642 print gray though new cartridge

i have cannon 3530 xerox machine ... it shows error code 350 ?? any solution ??

HI,

Please note that the #2 cartridge is the starter cartridge and the after market cartridge is the #1 cartridge.

The Lexmark X2470 printer uses the #1 cartridge which prints both color and black accordingly. While printing black it uses processed black. Hence, to print color images in "Black Only," please follow the steps given below:
1. Click on "Start," "All Programs," "Lexmark X2470 printer" group and then "Lexmark Photo Editor."
2. Click on "File" and then "Open" to select the color image file.
3. Click on "Image," "Mode" and then select "Grayscale."
4. Click on "Print."
This will print the image in gray.

Hello, Char.

Most inkjet printers are designed to require both black and color cartridges, even though you may be printing in black, only.

Please let me know if I have not understood your question.

Hope this helps.

The problem that you are experiencing is caused by the way the text is formatted in most word processing documents. By default envelopes are printed not in black, but a dark gray. This confuses the printer and causes it to use the color cartridge to process gray instead of using the black cartridge.

You can fix this problem with one of two ways:

1. Click on "Start", "Control Panel" and click on "Printers and Faxes." Right click on the "Lexmark Printer" icon and select "Properties." Click on "Printing Preferences." Go to "Quality/Copies" tab and select the option "Print color images in black and white."
2. You can also change the color of you text to a true black in your word processor. This will require you to resort to the word processor's documentation and help files.

Both of these settings will cause your printer to use the black cartridge instead of the color. If either one of these solutions solves your problem, it means your color cartridge needs to be cleaned or replaced. If you feel that the color cartridge should not be out of ink, please follow the steps given below:

Clean Nozzle Procedure:

1. Go to the "Solution Center" and click on the "Maintenance" tab.
2. Select "Clean to fix horizontal strips."
The colors that you should see here are black, yellow, magenta (a reddish purple) and cyan (a dark sky blue). You should notice the diagonal lines above and below the solid horizontal lines. These diagonal lines should be solid from left to right with no gaps.

If there are gaps in the lines or the print diminishes across the page, you should run the "Clean Print Nozzles" page a couple more times to try and clear it up. If you still have gaps at the top and bottom, you should "wick" the cartridges by following the steps given below:

“Wicking” Procedure:

1. Select "Install color/black cartridge" and remove the cartridge from the printer.
2. Get a damp paper towel.
3. Set the ink cartridge right side up on the damp paper towel so that the ink nozzles are against the towel and hold the cartridge in this position for about 15 seconds.
4. Now wipe the print head (on the bottom where the ink comes out) across in one direction only (left to right) until it looks clean.
5. Next dab the cartridge on the towel to make sure that the ink is flowing.
6. Snap the cartridge back into the printer.
7. On your computer, select "Old Cartridge installed."
8. Repeat the "Clean to fix horizontal strips" procedure listed above.

If this procedure does not help, please let us know so that we can continue with technical support.

Try to print from another program. It can't be as obvious as low(or completely dry) black cartridge could it? worth a shot? You can make a dark grey from the color cartridge just not dark black.

Take it back if it is new. If you've had it for a while and it's been sitting unused there may be dried ink in the print head. A visit to the Lexmark website might be useful for any troubleshooting. Good luck.

take the cartridges out and clean the spot they go into then clean them off also

just a wild guess. it may not be capable of printing in color.
check if you indeed have color cartridges installed.

it says B/W - Black and White.
