Arthur Entlich - Epson Cleaning Manual

Both require a fair amount of reading and the results you get are by no means guaranteed... Epson printers tend to recover best whilst Canon printheads can work again provided the head hasn't been stressed by a CIS install or poor maintenance. You mileage may vary.

Whether the printer is an Epson printer, hp printer, or a canon printer the general procedure for cleaning is the same. If the printer happens to be a bigger printer, for items such as advertising on larger format materials, the process is a bit more exaggerated but essentially the same.
