No print with black ink

[And-iovi_15]

Hi, I changed a few months ago my black ink cartridge with a new one - and everything was working properly - and then I never used it again until now, and I can't have the printer to print in black. Does anyone have any idea what could be happening to my printer? Here below I had an example of what yesterday was the results of the pages printed in black, but the same does not happen again today, just blank pages.

Thank you in advance. Cordially,

Andrea

Welcome to HP Support Community. This is a great place to post questions and find answers.
Thank you for posting your query, I will be glad to help you.

I see that you are facing print quality issues with your HP DeskJet 3755 All-In-One Printer.

Please follow the steps listed below to clean the cartridges.

1. Load plain white paper in the tray.

2.  Open the HP Smart app, and then click the picture of your printer to open the settings and management tools.

3. In Print Quality Tools or in Advanced Settings > Tools > Utilities > Print Quality Toolbox, select Clean Printhead to start the cleaning tool.

4. Review the Print Quality Diagnostic page that prints for defects and any instructions to resolve the issue. Run up to two more cleaning cycles, if necessary.
