Note: If you regularly print in black and white, but find that color ink is also used, your printer model uses a mix of black and color inks to decrease grain. Additionally, some ink is used from all cartridges to perform periodic servicing that prevents clogs and other print quality issues.
If your HP printer not printing black ink correctly, here`s what you should do. Using non-genuine ink cartridges. Printheads that have become clogged. Ink cartridges that are defective or empty.
Check the ink levels
Sometimes, the printer may not print black ink because it is low or empty. You can check the ink levels on the printer`s display, or by using the software that came with your printer. If the ink level is low, replace the cartridge or refill it according to the manufacturer`s instructions.
If you print in mostly black, your black cartridge will naturally run out faster than the color cartridges. However, some printers will pull a bit of ink from the color cartridges when you are printing solely in black, just to keep them primed for future use.
But with grayscale setting printing, the printer uses color ink or toner cartridges in combination with black to produce different shades of gray. This helps produce better shading and contrast in black-and-white images and graphics.
Click the Properties button. The Properties dialog box opens. Check the options on the property tabs to make sure that the appropriate color options are selected. If there is a checkmark in the box by Print in Grayscale, click in the box to remove the checkmark, and then click OK.
Reasons why your HP printer has ink but won`t print
This may seem obvious, but it sometimes happens: first make sure your paper tray has paper in it. Misalignment, clogged printheads, faulty data communication or insufficient ink levels can also be sources of the problem.
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.
Printers that use two cartridges (one black, one tri-color) can print if one cartridge is empty. To continue printing, remove the empty cartridge from the printer. If a Single-cartridge mode message displays, select OK. If you are using the black cartridge, prints are in black and white (grayscale).
