Cartridge issue HP Deskjet 3520

[Aine-1974]

I bought a HP Deskjet 3520 in 2015/16 and it worked for a short time until I bought new cartridges (the correct brand) which never worked properly. All of the functions of the printer seem to work fine and I can connect my HP app to it. The issue is that it only prints in pink / orange colour and not in black. When I touch the ink part or the black cartridge it is fully black so it’s not dried out. I have tried all the troubleshoot options so my question is do I buy new cartridges or is there something else I need to try? Thanks in advance!

Welcome to the HP support community.

I understand that you are getting print quality issues, I am glad to assist you.

Make sure the ink cartridges are properly vented

• Check the vents on the top of the ink cartridges. If they are clogged or obstructed, the ink cartridges might not work properly.
• Open the ink cartridge access door. The carriage moves to the access area.
• 
• Press the tab on the front of the ink cartridge inward to release it, and then pull up on the ink cartridge to remove it from the slot.
• If the error message mentions a specific ink cartridge, locate that ink cartridge, remove it from the carriage, and then continue with the next step.
• If the error message does not mention a specific ink cartridge, remove all the ink cartridges, one at a time, and then continue with the next step.
• 
• Examine the vent area on each ink cartridge, above the HP logo on the top of the ink cartridge.
• 
• If the ink cartridge still has the orange pull-tab attached, pull to remove it.
• 
• If the vent is clogged, use a straight pin to gently remove excess adhesive from the vent.
• 
• Clogged vent
• With a straight pin, gently remove excess adhesive from the vent
• Unclogged vent
• With the nozzle and the contacts facing down, push the ink cartridge into its slot. Press down on the ink cartridge until it clicks into place. Make sure that the color icon on the ink cartridge label matches the color icon on the slot.
• 
• Repeat these steps to inspect the vents on each of the ink cartridges.
• Make sure each ink cartridge is firmly in place in its slot. Run your finger along the top of the ink cartridges to feel for any that are protruding, and if any are, press down firmly until each ink cartridge snaps into place.
• Close the ink cartridge access door.
• 
• Try the print job again.
