If you can’t do this yourself as it is quite technical, we advise that you get a qualified technician to do this for you.
If your HP printer is still under warranty, then you should contact HP Support and not just any technician. This will ensure you get the best repair job with no fees attached. Besides, you could get a replacement if the printer cannot be fixed. Asking any non-certified HP technician to fix your printer will void your warranty.
