Reference for Canon ST5510 Inkjet Printer Maintenance Utility

After receiving the Grade A L1800 mainboard back from verification from BCH Tech and it still did not work on either of my computers (Win10 & Win11) as the same error was showing, I finally found a solution. I had to reinstall Windows (new install overtop of existing to keep all files and apps, but fixes any corrupted files) on both computers and not it is working properly. I apologize for the original negative review but rest assured it is not Kevin's fault. Thanks for you understanding and sorry for the original review.

I would encourage each and everyone who pays large sums of money for ink cartridges to consider buying these convenient and inexpensive Ink refills. Also, go to Youtube and learn how to use these inks in your used cartridges. I knew ink cartridges were expensive, but never realized the extent of this over-priced product! I use about 4-5 slight squeezes to fill my cartridges and the bottles last quite some time. I am so happy to be able to print in color and not have to worry about the cost of new cartridges.
