Print Head Cleaning Instructions Help with unblocking blocked printer nozzles

Inkjet Print Head Nozzles are well known for becoming blocked with dried ink or air, particularly Brother, Canon, Epson, and Kodak.  Fortunately these blockages can usually be cleared by running the standard head cleaning routine on the printer software.  Unfortunately this does not always work and it is necessary to perform manual maintenance to recover a correct ink flow.
There are two methods of unblocking the print head.  The first is to attach a syringe to the stalk leading to the print head.  We do not recommend this as it can damage the print head beyond repair. 
The best and safest way of clearing a blocked print head is to use dedicated cleaning cartridges which contain a specially formulated solution to dissolve blockages without damaging the heads.  Such cartridges can be purchased from the following store...  https://www.printercartridges.net/printercartridgesstore/index.php?main_page=index&cPath=222 

Some printers will allow you to just replace one colour, so if there is no black ink finding its way on to the paper, insert the black cleaning cartridge into the machine and print several full size pages of the image to the left.  Doing this will guarantee that a fair quantity of cleaning solution will be pushed through the print head nozzles.  Finally, replace the normal black cartridge and print as normal.  You may have to print a few pages before the black ink begins to appear again.
If the nozzle remains blocked after performing the above operation, then repeat the exercise, but this time leave the cleaning cartridge inside the printer overnight.  This will allow the solution to eat away at the blockage.
Cleaning cartridges are usually 75% successful, unfortunately however there is no guarantee that they will clear the blockage. 

Cartridges that contain microchips may not like to mix with the special cleaning cartridges chips, so you will have to install the whole set.  This makes using the following colour print images more important as you do not want to pass too much fluid through the heads that are not blocked.  If the cyan, magenta, yellow, light cyan, or photo cyan colour(s) are blocked, then print one or more of the surrounding images. Right click on them and select save image.  Then print full A4 size pictures of them.  As the cleaning fluid takes over from the ordinary coloured ink you will notice the colour gradually fade away.
