So did I; another Canon (MX526) for less than the price of the cartridges in the MP800. Pity that the new world is all about RATA (Replace And Throw Away).
What could be the reason for the PGBK cartridge not printing in my test (Hoops) and the other messager.? My printer prints OK for picture files (as does his) and prints B&W pics perfectly as well so it doesn't seem to be the nozzle. It has somethin...
I have exactly the same problem. The PGBK cartridge does not print when I do a nozzle check. Jpeg files print ok in black&white but Word/Excel do not!! I changed the PGBK cartridge but ..... same problem. Anybody can help??
