I just had this exact problem on my HP 5514. Black won't print after running out of black ink. New cartridge no good.
I tried everything-no good. I suspected the pinholes in the printhead were clogged with dried ink because I didn't change cartridge in time.
The fix that worked perfectly was when I hacksaw top off old black cartridge & removed all foam wicks so now I had a funnel(can see clear thru). I installed the cartridge & filled it with alcohol, printed page & did head clean; then printed few more pages. Problem cleared almost immediately. I then soaked up extra alcohol inside cartridge with paper towel. Removed modified cartridge & installed good one. I guess this could be done for colors as well. I don't know if this is a proper procedure, but it sure worked well for me.
New cartridge wouldnt print but sounded like it was printing. You can check ink levels clean or align cartridge by pushing menu then tools. I cleaned contact points w qtip and alcohol. What seemed to work is putting alcohol on cartridge where ink is released and putting back into machine wet did this three times first time little dots of ink then a faint print and now it is printing must have been dried ink further then I could access.
hi i am a certified Canon repair tech for this fax. the problem that you are having is very common and has to do with two things. the cartridge and the purge/cleaning unit. what you can try is this open the printer and center the carridge unit and remove the cartridge. unplug the machine while it is still centered. on the right hand side you will see the purge unit. in the center of the purge unit is what looks like a retanglar pad. mix a water soap solution and apply to pad just soaking it. let it sit for a few minutes. take the ink cartridge and wipe the bottom of the cartridge with a damp soapy cloth. also if you look at the cartridge there is a little breating hole you can hold a cloth on the bottom and gently blow in that hole it will purge ink through the bottom of the cartridge. install the cartridge in the machine close the front door and replug in the power cord. you might still have to run a few cleaning cycles. hope this helps.
Although you may not use the other colours the cleaning assembly cleans all the cartridges hence the other ink gets used.
To trick the machine into thinking there is ink in the cartridge, place some black tape over the top of each cartridge facing front of the machine. This fools the sensor into seeing no reflected light and reads that there is ink in the cartridges you do not use.
Pleas enote that if you do this on a long term basis it is liley the head will dry out and may damage the head - use this advise to get urgent prints out.
