I have an HP Officejet 7500a printer it is not printing black.

[Borkkum]

I have an HP Officeject 7500a printer that hasn't been working for close to 6 years (every now and then I call it), I needed it and bought original cartridges (as I always do), and I find that the black color doesn't print. I've already cleaned it, I've tried to align the head and it doesn't print black. What will be the problem and how will I solve it? Can anyone help me. Thanks.

Hi @Borkkum 

Welcome to the HP support community.
 

I understand you're experiencing an issue with your HP device, and I apologize for any inconvenience this may have caused. I'm here to help you today.
 

Clean the printhead Solution: 

try cleaning the printhead. After cleaning the printhead, print a print quality report. Evaluate the print quality report to see if the print quality problem still exists. For more information, see:

 Clean the printhead If your printed output is streaked or has any incorrect or missing colors, the printhead might need to be cleaned. 

There are two stages of cleaning. Each stage lasts about two minutes, uses one sheet of paper, and uses an increasing amount of ink. After each stage, review the quality of the printed page. You should only initiate the next phase of cleaning if the print quality is poor. If print quality still seems poor after you complete both stages of cleaning, try aligning the printer. If print quality problems persist after cleaning and aligning, contact HP support.

 NOTE: Cleaning uses ink, so clean the printheads only when necessary. The cleaning process takes a few minutes. Some noise might be generated in the process. Before cleaning the printheads, make sure you load paper. For more information, see Load media. Not turning the printer off correctly can cause print quality problems. For more information, see Turn off the printer. To clean the printhead from the control panel 

1. Load letter, A4, or legal unused plain white paper into the main input tray. 

2. Touch right arrow , and then select Setup. 

3. Touch Tools, and then select Clean Printhead. Align the printhead The printer automatically aligns the printhead during the initial setup. You might want to use this feature when the printer status page shows streaking or white lines through any of the blocks of color or if you are having print quality issues with your printouts. To align the printhead from the control panel 

1. Load letter, A4, or legal unused plain white paper into the main input tray. 

2. On the printer control panel, touch right arrow , and then touch Setup. 

3. Touch Tools, and then select Align Printer. 

Print and evaluate a print quality report Print quality problems can have many causes: software settings, a poor image file, or the printing system itself. If you are unhappy with the quality of your prints, a Print Quality Diagnostic page can help you determine if the printing system is working correctly.
