Brother Printer – No Black Ink Printing for MFC 490CW

hardware-failureinkjet-printer

I have a Brother model MFC 490CW color printer than has three color ink and one black ink cartridge.

I've replaced the black ink cartridge, but I still get no black ink being printed, the three color inks are printing correctly. What could be going wrong and how might I fix this? The printer had been idle for about nine months, could there be some kind of clogging? The printer's clean utility did not help.

Best Answer

I cleared the ink jets on a brother MFC-490CW on the first try.

  1. I had no black after 3 or 4 Power_P ALL cycles.
  2. I took the alcohol injection route.
  3. I removed all 4 ink cartridges.
  4. Using a flashlight,I found the inlet tube for the black ink.
  5. Using the thin rubber tube from an antifreeze tester which fit snugly over the black ink inlet tube,I injected about 1/4-1/2 oz. of Everclear(90% ethyl alcohol) into the tube under pressure.
  6. replaced ink cartridges.
  7. I ran the Power_P cycle once more.
  8. Black functioned 99% on first test page and 100% on second.
