The Cause of Clogs

Printheads clog because nozzles get blocked by either air or ink. Clogs usually happen when: You keep printing with depleted ink cartridges. Using empty ink cartridges can result in air bubbles that can clog your cartridge and/or printhead.

Clean the print head, if necessary. Make sure the paper size, orientation, and layout settings in your printer software are correct. Make sure your document does not contain blank pages. If your printer software has a Preview option, you can check for blank pages before you print and remove them, if necessary.
If the ink level is sufficient, but the printer still does not print black ink, you may need to run a cleaning cycle. A cleaning cycle is a process that cleans the printer heads and removes any clogged or dried ink.
If your PC or the LCD screen on your printer is telling you that your ink cartridges are full but no ink is passing through to the paper, then it`s most likely that you are dealing with a clogged printhead. Blurry documents and images that appear faded are also signs that it`s time to remove the excess ink.
Clean the print head, if necessary. Make sure the paper size, orientation, and layout settings in your printer software are correct. Make sure your document does not contain blank pages. If your printer software has a Preview option, you can check for blank pages before you print and remove them, if necessary.
Do a hard reset on your printer. To do this you just need to turn off your printer, unplug for a few minutes and then plug the printer again. If that still doesn`t work, try turning the printer and your computer off, and then start it back up again. Try uninstalling and then reinstalling your printer driver.
There are numerous possible causes for a printer that`s randomly producing blanks. The most common ones are empty ink cartridges, improper cartridge installation, and congested nozzles. Driver and software issues can sometimes cause this problem as well.
