My lexmark print black - Lexmark T644 Laser Printer

Do a Clean Printhead operation.
This will usually correct the problem.

If your color ink is already empty or not substantial for printing, then you must replace it with a new cartridge. The Lexmark printer will continue to print when there's substantial ink in the cartridges.
If you prefer to print in black and white as your default print setting, please follow the steps below: (make sure your black and color cartridges ink levels are good)

For Windows OS:

1. Go to Control Panel.

2. Open Printers and Faxes.

3. Right-click on Lexmark 3600-4600 Series print object and click on Properties.

4. In the Lexmark 3600-4600 Series Properties window, go to Advanced tab. Click on Printing Defaults.

5. In the Lexmark 3600-4600 Series Printing Preferences window, under Ink Use, select Print using black ink only. Click OK.

6. Click OK button in the Lexmark 3600-4600 Series Properties window to save the changes.

Your printer will print in black and white draft mode the next time you send a print job to the printer.

For Mac OS:

1. With the file (you wish to print) open, go to Print. A window will pop up.

2. Select the Lexmark printer.

3. Expand the arrow pointing down beside printer name if you're not able to see other options for printing. Look for Quality and Media.

4. Under Paper tab, select Print in Black and White.

5. Save this as your default print setting. Click Presets option and choose Save as. You can personalize the name for this default print setting (e.g. Black and White Draft or My Setting).

Select this Preset name every time you print your files/documents.

There are some Lexmark color laser printers that are capable of black-only printing w/o the color cartridges installed, unfortunately, the Lexmark C720 printer is not capable of printing with only the black cartridge installed.

Hi MikeC,

Most of the time this is due to the black cartridge being out of ink. The Lexmark uses all the colors to create black when the black ink cartridge runs out, but won't let you print black because it is essentially saving ink.

Hope that's the reason and it isn't the printer failing. Good luck! :)

Clean your printer cartridge printer maintainence program or alignment or head clean

It's possible the black nozzles may have become clogged or the black cartridge may not be properly seated. Recommend you contact technical support via www.lexmark.com.

Unfortunately the printer wont print unless there is ink in both cartridges

hmmm...paperman..that's unusual to say the least..
