To determine which cartridge is the issue, we suggest running a print quality diagnostic report. A print quality diagnostic report is basically a test page that will give you clear idea of how each specific cartridge is performing.
We will be using an HP Officejet 8610 as our example. If you own a different printer, be sure to consult your printer's user guide for specific instructions.
1. Touch the “Setup” button on the printer’s display.
2. Then, touch “Print Reports”
3. And then select, “Print Quality Report”.
If the print quality looks poor or you are missing color bars it may be time to replace the spotty cartridge.
Before you run out and buy a new cartridge, you should first try running a printhead cleaning, there is a good chance it could clear up the issue right away. To clean the printhead from your printer’s display on your HP OfficeJet 8610, follow these instructions:
1. Touch the “Setup” button.
2. Then, touch “Tools”
3. And then, select “Clean Printhead”.
The cleaning process should take around two minutes to complete. Once it is done, you can try running another print quality diagnostic test and compare results. If the quality is still poor, try running a second printhead cleaning. We don’t recommend running more than 2 or 3 printhead cleanings because it can deplete your ink cartridges quite a bit. If you run a couple of cleanings without any improvement, it might be time to replace your ink cartridge.
