For something like this, you may need to do a "Nozzle Prime" on the cartridges. But first, do you have your air filters installed on the ink tank reservoirs? Make sure that the air filters are installed and check to see if you have any ink trapped inside of them. Inks trapped inside the air filters will restrict the air passing into the cartridges and will cause the colors not to come out. Same thing will happen if you do NOT have the air filters installed. IF they are not installed, they will eventually start to get faded lines and eventually turn blank on the pages.
I wouldn't recommend doing any head cleanings if you can do a nozzle prime first. Nozzle Primes would require you to use the syringe to draw the ink from the nozzle of the cartridge. By doing this , you will improve the quality and the ink flowing from the cartridge, underneath the printer.
Here is a video showing you how to draw the inks from the nozzle . Do this for each cartridge 2-3 times and you will see it improve.https://www.youtube.com/watch?v=McHXJea9Xts
