Question about Printers & Copiers
Printer is producing prints with an overall greenish colour. I have run the cleaning programme more than the stated three times and performed deep clean at least twice. Nozzle check appears ok, although the colours are very light.Could it be the printer head is worn out? Printer is about three years old and gets regular but not intensive use. Cleaning is performed about once per month because if the printer is left for a few days banding occurs when printing is resumed again. The users manual only seems to point me in the direction of Canon servicing if the steps described in the manual don`t work.
Greenishness output is due to a lack of magenta (cyan and yellow combine to make green). The magenta print head nozzles are probably clogged with ink. Canon would have you buy a new print head ($75 ?). However, you can clean it yourself.
First get out some paper towels or heavy tissue paper (maybe napkins); something that doesn't give off a lot of lint is best. Also get a roll of cloth or rubber tape, duct tape works great. Get a bottle of something like 409 or one of those 'orange' cleaners that you use to clean your counter top. You'll know it is the right type of cleaner when the ink continues to come out of the print head during this procedure.
First you'll need to protect the circuit board area on the back of the print head by covering it with one or more pieces of tape. This is to prevent the cleaning fluid from getting behind the circuit board and shorting it out later when you place the print head back in the printer.
Place the print head straight up as it is in the printer on a folded, flat piece of paper towels while gently pressing down. The remaining ink should begin to appear around the edges of the print head as it is being absorbed. You'll have to continually move the print head to other clean spots on the tissue as it soaks in. The tissue helps by drawing out the ink (capillary action) and by keeping the individual colors from going into the other color nozzles. Make sure that the tissue you place the print head on is always flat and not curled or folded; this could damage the nozzles.
Spray the cleaner into the top of the print head where the cartridges normally reside. I will refer to this as the cartridge reservoir. Spray enough cleaner into the reservoir to cover the round spongy contacts that connect and align with the ink cartridges. This will soak into the print head just like the ink from the cartridges and begin pushing the old ink out the nozzles onto the tissue.
Continue squirting cleaner into the reservoir and moving the print head to clean spots on the tissue until only clear cleaner comes out onto the tissue. For the clogged nozzles this may take quite a while and lots of tissue, but the cost of these supplies is certainly less than the cost of a new print head! Don't run water through the print head!
Now carefully remove the tape and place the print head back in the printer and replace the ink cartridges. You don't have to wait for the cleaning fluid to dry and, in fact, you don't want to. As soon as the ink cartridges are in place the ink will begin flowing through the nozzles. Now run a alignment test and nozzle check to test out the system. Then resume printing those family pics, nudes, charts, etc.
