Black is used on all prints. Did you pull the tape on the new cartridge?

Canon MP970 prints blank pages. How can I FIX that problem?


Some times when you get a new cart. a fine film can be blocking the
exit hole,check that this is clear by shaking the cart. up and down
over a large piece of paper ,if you do not get any ink out ,take a small
pin and gently insert it into the exit hole and move it around in a circle,
don't go to deep,then try shaking it again..? Another idea is to replace
all the carts.(colour ones also) as some printers wont work unless you
do this, after changing carts. disconect your printer from mains supply
and leave for about 15 minuets to reset..Hope this works for you
good luck. T.C.

Dumb question. Did you pull the strip from the toner cartidge? OEM or aftermarket? I would try the old cartidge and see if it changes if you don't have the old cartridge anymore I would contemplate replacing the one you just purchased or taking it back to where you purchased it and get an exchange for a defective cartridge.
