A few months back I had a similar issue with Magenta, lost it completely tried several carts (all OEM I.S Inks) many head cleans failed to resolve it. Eventually and reluctantly I pulled the print head and went through the recommended gentle window cleaning method (Panos) but to no avail. Then concentrated on the magenta input sucked/pushed fluid through a 20ml syringe saw a flash of pink, reinstalled nozzle test perfect.

My printing is pretty light anyway but resolved only print what was necessary, yet we know other forum members print thousands of pages/photos on numerous printers with few problems. Now the original problem has returned only this time it is the cyan. 2 nozzle checks, 1 deep clean, 3 different carts and the last one blew through to ensure it flowed easily but still only 20-30% showing on the nozzle checks or none at all. Yesterday I repeated the syringe method just on the cyan pick up nozzle check fine.

Today 1 web page obviously off, nozzle check again zero cyan. Any suggestions I still feel cart feed the likely culprit. I am getting fed up with how delicate these Canon printers can be but the printer is a pretty essential piece of kit in the computer set up.

1) Try a different known working or new CYAN cartridge or purge your current Cyan cartridge and retry.

2) Please post a nozzle check on the forum.

3) You said "My printing is pretty light" which I could take as the print is faint in intensity or your have many days in between print jobs. Which is it? The people who seem to have the least problems with clogging are those who print at least once a week something that uses all the cartridge colors, like a nozzle check at least. Jimbo123 probably prints most days of the week and has had flawless function. His print heads last a long time.

Your purge unit wouldn’t be playing up would it,
have you checked to see if it’s working properly..

@barf12,...Stratman is right,..you need to print something every day or at least 3 times a week. This keeps the ink in the head from drying up as well as the ink carts and the entire chain. I have one printer I have used for 7 years with the same ink carts,..just refilling them as required. But I make sure I print something almost every day.

First you need to get your printhead clean. Using the push/pull syringe did get it just clean enough so it would print a nozzle check which takes the absolute minimum amount of ink. The problem is most of the clogs hide in the input filter screen or in the internal channels that feed the nozzles tub. The point is that the ink path can be open just enough for you to get all of the nozzles primed with new ink and print a decent nozzle test print,.. but it won't take long for that to clog back up. To really test your printhead after you think you have cleaned it you need to print half a page of 6 color test bars to prove that the head and the ink carts can sustain printing and that you really have the head clean. Send me a note with your email address and i will send you my instructions and a copy of the 6 color test chart.

To clarify I do print every day and a nozzle check every week hence my frustration with this regular losses of printing function. Not tried purge test (The Hat) but will of course try that Trigger 37 comments seem to indicate print head blockage which I will pursue.

I have tried all my stock (3) so do not have a known good one but as stated the blow test was fine on the current one (stratman)

When I had a similar problem with the Magenta I did buy both OEM (ouch) and compatible which worked. This made me think my ink/methods/carts were bad. However when I started to introduce my refilled ones they worked perfectly OK. If a new OEM/Compatible works I assume that proves that it is a cart flow problem rather than the print head which I like to leave alone if possible. I envy Jimbo123 but obviously he is doing everything right and somewhere I am not.

Anyway thanks everybody for their suggestions not tried to upload yet still getting to grips with the new lay out

Keep at it. If you resolved your problem before then chances are you will solve your current issue.

If you can, try the "Upload a File" button found below the window where you type in a post and let us take a look at your nozzle check. We are a visual bunch on he forum.:ep
