Canon Image Prograf IPF605 banding through colour on prints

KTBerwick used Ask the Experts™
When printing from the above named printer there are pink bands running through grey colours and yellow bands running through green colours.  I have carried out print head cleaning various times as well as print head alignment and removing and refitting the paper roll.  I suspect it could be a print head problem but would like to be sure as this is an expensive part to replace.  Genuine Canon ink cartridges are being used.

Sounds very like a problem with the Cyan head.

Green - Cyan =Yellow
Grey - Cyan = pink (Magenta+Yellow)
Purge-Cyan.tifA cyan print head blockage is most likely.

Your printer has 5 colors:

matte black

I have attached the purge pattern for your cyan head.

Your cyan head (other heads if needed) can be purged with this handy purge info. & patterns:
Purge the cyan head (& others if needed) & if this does not clear the blockage then you may try Manually Cleaning the Printer Head (Heads):

Steps for Manually Cleaning the Printer Head
Step 1 - Remove the ink tanks and printer head. Remove the ink tanks from the printer head (tank holder) and seal them in a zip lock or other sealable plastic bag. Set them aside, preferably propped upright.

Next remove the printer head (it snaps out). NOTE: You may want to wear latex gloves to help keep ink off your hands.

Step 2 - Soak the printer head. There are multiple suggestions on ways to clean the printer head and all have some variation on the following:

Get a small, shallow pan and lay down a layer or two of paper towels in the bottom of the container to protect the printer head circuitry from contact damage.
Heat up (via microwave) enough purified/bottled water to cover the paper towels. You can also use a 50/50 mixture of ammonia and distilled water (about a pint will do). Heat the mixture in the microwave for about a minute or so - it should NOT be boiling.
Slowly pour the water or mixture over the paper towels so that you have approximately 1/2 inch of liquid in the bottom of the pan.
Set the printer head into the container on top of the towels. You should see ink 'bleeding' out. Move the print head to several different spots (about a minute each spot) and shake gently. This will dissolve the ink clogs.
If the printer head is badly clogged let it soak for 3 to 4 hours or overnight. You can move it slightly to a different spot every hour or so.
Alternative Soak Method:
Mix a 50/50 solution of warm water and Windex and place in a shallow container, enough to cover the base of the printer head and ink ports. Leave for 2 hours while agitating the unit occasionally. Remove from the mix and lightly scrub the base and internal ink ports with an old soft toothbrush. Do not scrub the gold contacts but don't be concerned if they get wet. Return the unit to the mix for another 2 hours and agitate occasionally. Remove and scrub again as before.

You need to download + then save the attached Purge-Cyan.tif  then open it.

Nice procedure ! :)
Also, even a "Genuine Canon ink cartridge" can be faulty?

So also try a new cyan (& others if needed) ink cartridge before you try Manually Cleaning the Printer Head (Heads) or think about replacing your head.! :)
