Try Reseatting the Catridges, follow the steps

* Switch on the unit and open the lid on the top cover
* Remove the Catridges from the printer
* Then just re-install the Catridges
* Then just close the unit lid or top cover
* After closing, cycle the power of the device by turning of the device for a few seconds
* Turn the printer back on
* Try printing a test page

If the before solution did not work, try the next one.

Wipe out the Catridge contacts
* Turn the unit on and open the lid or top cover
* Remove the Catridges,
* Use a clean cloth or a clean coffee filter to wipe the catridge. Wipe the catridge so briskly
to clear the waxy lubricants from the gold contacts.
* The contacts inside the printer may also require the cleaning. Use the clean cloth to wipe
from top to bottom of the contacts.
* Re-install the catridges and close the printers lid or top cover.
* Then try printing the test page.

If even the second solution didn't work try the last solution down

Perform a hard reset on the device
* Verify the unit is power on.
* Then unplug the power cord from the printer
* Wait 30 seconds
* Press and hold the power button in the front panel
* Plug the power cord back into the printer
* Open the top lid or top cover and reinstall the catridges
* Turn the device on
* Print a test page.

If the problem is unsolved, try replacing a new catridge.

How to remove catridge

Catridge removal should be done along with the software support. Click on printers and faxes. Select your printer from there and click properties on it. Then Click on check ink levels in your printer. It will automatically show for the error if there is any empty catridge and you will get a screen with button named "Remove Catridge" On clicking it, the print head will come and stop near the opening from where you can open the print head and remove the catridge. Press the small tap like button on the side and while pressing it, the catridge will become loose , and pull it on the top. You can remove it by doing like this.

Red colour toner replaced Cartridge with a new onebut still no print coreect. Replaced the Yellow colour toner Cartridge with a new one but printing is not clear.

this problem regards the head of the catridge. u have to do clean due to dust it may happenlike that. u clean inside with the cotton cloth on the print head and refix the all color catridges. when u remove ur catridge u have to close all the sides due to avoiding dry.
the second reason when u purchase ur catridges, check whether the catridges are valid date.

Move the Catridge Carrier which holds the catridge from right to left and from left to right for about 10 times............ 4. Try to make a copy without the catridges........If this works and it gives a Blank Page out............ 5. Insert both the catridges turn the printer off and turn it on again........... 6. Now it should work fine........ Good Luck......
