My HP printer not printing black-ink – why

Your printer is working, but the printed papers are not coming with the right or instructed colors. The HP printers, especially the inkjet printers, face this problem quite frequently. Under this situation, some users start believing that black ink needs a replacement. However, it does not only mean that the cartridge needs a replacement. This issue sometimes occurs due to the use of a local cartridge and demands a genuine HP cartridge be resolved. Evaluating the quality report is the other thing you need to do if the HP printer black-ink not working properly. We have mentioned a set of troubleshooting tricks, starting from the evaluation of the print quality report.

Is your print quality satisfactory?

Your cartridge might be full of ink, but it is not necessarily an error-free cartridge. If so, you will be getting poor quality printouts from your HP printer even if it is high on ink. Simply replace the cartridge if you found it broken or defective.
