No problem, thanks for confirming. I just wanted to make sure this was not a driver issue on the computer (if the nozzle page looks fine, then it may be). However, in this case, since the nozzle page is missing some parts, it looks like it is a hardware issue, meaning there is a clog on the printhead nozzle that is preventing black ink from spraying onto the paper correctly.
Please go ahead and open the printer, and take out the ink cartridges, and make sure all pre-packaged tape has been taken off them. Then reinsert the cartridges firmly, you should see the ink lamps lit red and steady. If you don't, please stop here and let me know.
Then, try 2 more regular cleanings, then 1 deep printhead cleaning, please click HERE
and use the directions there. If that doesn't help, and you still don't see the PGBK line at all, leave the printer overnight and try another cleaning in the morning. Leaving it overnight allows the clog to soften.
If there is still no change, you can soak the printhead (the part that holds the ink cartridges) to dissolve any clogs on the nozzle where the ink sprays out. You will need a container large enough for the printhead, q-tips/cotton swabs, paper towels, a lint free cloth, and some distilled water.
Open the printer and remove all ink cartridges, then seal them in a ziplock plastic bag that has a damp paper towel inside it. This will keep the ink cartridges moist so they don't dry out. Set these aside, propped upright so no ink leaks out. Now turn off the printer and disconnect all cables from the back of it. Place a folded paper towel in the bottom of a container large enough to fit the printhead. Fill it with 1 inch of very hot, but not boiling water (Heating for one minute in the microwave is fine). Now unlatch the printhead and take it out:
Set the printhead gently in the container, nozzle side down. There should be enough water to soak the nozzles but not to touch the electrical contacts on the back of the printhead. Pour some heated water inside the printhead just to wet it. Let it soak for 1 hour, then drain the container and refill it with another inch of heated water. This time move the printhead to a different spot on the paper towel and let it soak again. Repeat this for three more hours.
Now take out the printhead and rinse it thoroughly under your faucet water in the sink. During the rinse use your finger to lightly tap the round nubs where the ink cartridges connect to the printhead. This will create pressure to force clogged ink through the nozzle. If there are rubber gaskets around each nub take extra care not to dislodge or lose these. It's ok to get the electrical contacts on the back of the printhead wet we just didn't want to soak them earlier.
If your Canon printhead has a ceramic plate beneath the nozzles, similar to what is shown below:
Please click HERE
and follow the extended instructions there to clean this part thoroughly (Credit to Mike Boesen).
Now turn the printhead upside down and rinse the nozzle on the bottom. Keep rinsing it until no further ink comes out, it may take a while depending on the severity of the clogs. Take out the printhead and lightly blot it on a damp, folded paper towel a few times. Now rinse the printhead some more, specifically until you see no more ink coming out of the nozzles on the bottom of the printhead. If you see gummed up ink that won't rinse off you can take a dampened q-tip and very gently rub it off the nozzle. Do not put any pressure on the nozzle.
Then lightly dampen a lint-free cloth (not paper towels), and use it to wipe the copper contacts on the ink cartridges (if any), and inside the printhead where the contacts meet the cartridges (if any). Do this until no ink comes off the cloth. Also clean the electrical contacts on the back of the printhead, but wipe from bottom to top, in one direction.
Finally you will need to rinse the printhead off with distilled water, this will remove any minerals/solids from the tap water you used to rinse out the printhead, which can cause further clogs later if not removed. Then using a dry paper towel and q-tips, dry the printhead as best you can. Very gently blot dry the sensitive electrical contacts on the back and the nozzles on the bottom of the printhead. Set it on some folded paper towel to completely air dry, then reinsert the printhead along with the ink cartridges:
Plug in all cables again and turn the printer back on, then try a few more printhead cleanings as we did earlier.
