Question about Canon PIXMA MP470 All-in-One Printer
This symptom signals blocked printhead, you need to do bit of cleaning, not necessarily cahnge the cartridge.
follow this procedure:
1. download test page with alternative from this site black:
2. print page each and assess the colour and streaks. if on the beginnig of the page you do have errors and on the bottom all is corrected, this meant that you just cleaned your printhead nozzles and problem is solved.
3, if problem persist, from stationery store purchase few pages of absorbent paper, weight of about 120 to 160, do not use thicker than 160 and print these colour pages again,
4. print control page again and see if any improvement was made, if there were no changes, follow this procedure:
a. remove cartridges from craddle
b. determine what is ink solvent, water, isopropyl alcohol or methylated alcohol - correct solvent will be that which do not precipitate or curdle the ink
c. touch with absorbent tissuebottom of the cartridge and check if it is leaving even print, if not, whipe once with solvent
d. put a drop of solvent on gold/silver buttons inside of the craddle, allow to sink for about a minute, whipe off with absorbent tissue
e. put again a drop of solvent on the button in the craddle and insert ink cartridge
f. print test page, page will be very weak on the top (solvent print first!) and improve as it prints down, if necessary, print again colour or black test page from 1.
this should solve your streaking head problems, if they still persist, this meant that print heads are really well blocked by caked ink and usually is cheaper to change printer than change the head in it...
