Problems with Canon i560
 

I have been using this printer for about 2 years, printing on HP everyday photo paper/semi-gloss, with good results.

Recently the printer won't print a clear, sharp cover. Covers are somewhat 'oversaturated' , text is readable but colors are seeping into each other. It looks like the printer is sudenly using too much ink. I tried to change settings but the result is always the same - the cover is in some areas unsharp, blobs of ink :(
I am using Canon ink cartridges, btw.

I will try to print on Canon paper to see if I can get better results, but I would like to know if anyone here has i560 and what type of paper/printer settings are you using with it.

TIA
