Also have noted black ink has spilled on bottom of housing near black cartridge . Printer been in use 14 months
I'm having the same issues with my Deskjet 3521 that London 74 had. I have done all of the suggested troubleshooting items and nothing works. My black ink still will not print, even after replacing with 3 different new HP black ink cartridges. Any suggestions on what to do to make it print black ink?
HP recommends that you use genuine HP ink or toner supplies. HP cannot guarantee the quality or reliability of non-HP or refilled cartridges. If you do not use genuine HP cartridges, the steps in this document might not resolve the issue. To check the authenticity of your cartridges, go to hp.com/go/anticounterfeit.
Solution 2: Allow automatic servicing to complete
Your HP printer has an automatic servicing routine that can solve many print quality issues. There is nothing you need to do. The print quality should improve a few hours after you experience the issue.
If you cannot wait for the automatic servicing routine to complete, continue with the following troubleshooting steps.
Solution 3: Check the paper
Use the following guidelines to make sure that the paper you are using is appropriate for the print job. If it is not, reload the printer with an appropriate paper type.
