Jul 14, 2020 - Wrong cartridge: Sometimes you will see that the Kyocera Printer is printing blank pages, even your ink cartridge is full. The reason behind ...

..

Try running cleaning cycle multiple times. Sounds like ink tubes may be clogged.

mayby cardridges are empty

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.

my canon pixma ip3000 prints blank, I have tried all the maintenance functions but still prints blank. pls help...

Not to sound like a smart aleck...do you have enough toner in it? Can you print a test page? Sounds like a toner issue to me.

Is it a new genuine cart? If so, I have had this problem. Run multiple copies of black only text, Run 50 copies, will still spit out blank pages.Then head clean. If no black repeat. I did this for around 200-250 copies then Volia! black. Hope this helps

Make sure all cartridge are install and secured into place...(take all the cartridge out and back in ) close front door cover and it will go into cartridge calibration...If not, press the "menu" key and with the arrow go to print quality and confirm with the enter key. Go to calibration and confirm...

Let me know....
