I have a Canon Pixma MG6650 which I'm having trouble with aligning the print heads and my prints all come out in disjointed bands. Auto alignment doesn't seem to make any difference and my problem is that I don't know how to proceed with the manual alignment

Several of the columns have equally extremely streaked patterns so how do I choose?

When I print out the 'print head alignment value' a few of the boxes print out well and these seem to correspond to the columns that at least have unstreaky patterns to choose from
 
if a deep clean is not working there may be ink slug or paper pieces under the print head or the print head has a few bad jets on it. take out the print head use soft cloth and rubbing alcho. clean it real good. check under and around the print head for any paper or lables. look inside the printer for any paper jams. if the issue still there see what the cost to replace the print head is.

thankyou I will look up on how to take the print head out, the printer has been giving errors saying 'something' went wrong and to check for things stuck inside but I couldn't see anything
