Prints in light grey instead of black

[Kushal0803]

All of a sudden today my printer started printing only in light grey instead of black.  I have checked ink levels on the black cartridge but it is at over 90%.  I have cleaned printer heads.  I have made sure the  preferences are set to grey scale  off.  What else can I do to get back to printing  black?

Hi @Kushal0803,

 I'd like to help!

I understand you are facing print quality issues

To assist better-

1) Does the copy print out the same way? 

2) What's the application you are trying to print from? Have you tried printing from a different application or device? 

While you respond to that, let's print a Print Quality Diagnostic page -

1. Load paper into the input tray.

2. Open or search for the HP folder in your list of installed software programs, click the folder for your printer, and then click the name of your printer.

   The HP Printer Assistant software opens.

3. On the HP Printer Assistant window, click Maintain Your Printer.

4. Click the Device Services tab, and then click Print Quality Diagnostics Page ().

Post the Print Quality Diagnostic page here so we can help you further. 

You may also refer to this document with steps to fix the " Print Quality Issues" issue applicable for your printer -  Print Quality Issues

 Also, try updating the printer's firmware - HP Printers - Updating or Upgrading Printer Firmware 

Hope this helps! Keep me posted.

Thank you for getting back to me.

Try the single-cartridge mode

The printer you own can work in single-cartridge mode, wherein the printer will be able to print with one cartridge in the printer. Which will help us identify if its a cartridge issue or a printhead issue

To try single-cartridge mode follow the below steps:

• remove the black ink from the printer, leave the color in and try printing
• then remove the color ink and, insert the black  in and try printing

 If the issue persists, I'd suggest you contact HP in your region regarding the service options for your printer

Hope this helps! Keep me posted.
