Newly installed n0016 black ink cartridge shows

duhhh on my part. i had removed the triple colored plastic coating i normally do and proceeded with the addition of the new print cartridge. it didn't print black and i checked and rechecked and reinserted. then i wrote to you guys. i took both cartridges out and caught a glint on the bottom of the black ink. blind bat here.. there was a section of tape that i failed to see (with my glasses on yet). so that was the solution. tape removal. my prior cartridges each had the one tri colored strip. i failed to feel or see the additional section of tape. thank you fix ya- i really would have felt stupid having you guys spend time assisting me.
