Error code OK first I opened my printer (420 cn)) and cleaned the print head.  It would not print or load ink.  I then Opened it again and cleaned the ribbon and the entire printer put everything back together again. Still it will not print. I get error code 51.  I did a deep clean menu -mode - blue key 4 times - 7-6-4 I then get par. init. error.  I press 99 to exit and start over with the deep clean and I am back to error code 51.  I have checked to see if there are any broken gears or anything that is not back in place can not find anything.  The problem began when my black ink would not print. I need help!!!

print heads are more than the cost of a new machine, approx Aus$150 plus fitting, not worth doing and needs 4 new inks to run inital purge too print heads are more than the cost of a new machine, approx Aus$150 plus fitting, not worth doing and needs 4 new inks to run inital purge too

With your next printer stick to gen inks, recycled inks work out more expensive in the end because you neede to have printer fix, life is shortened, and cost of frustration with bad print quality. Laser machines are a lot cheaper to run than ink but colour laser is expensive units to buy. Running cost of a inkjet is 20-30cents per sheet, laser is 2-10. If most of your printing is B/W then buy a laser based machine and do your colour printing at the photoshop heaps more economical and reliable, thanks for rating it is appriciated.
