I have a canon mp730 and since I have replaced my ink cartriges I keep geting a wrong cartridge message. I have checked and rechecked installation and re booted several times to no avail. I have checked and removed the printer head to see if anything looks abnormal also but see no visible problems. If there is an obvious answer please let me know. Other wise I guess it will have to go in to a tec shop. Thankyou!!

Clean the print head/cartridge with Isopropol Alcohol (rubbing alcohol)and Q-Tips, The nozzles, the contacts and all the excess ink that had acummulated around the nozzles. The error message should clear.Run through all the maintenance checks and alignments. If this does not fix it, the print head needs to be replaced about $45-$60 from Canon.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it and give a testimonial for my response. Thanks, Joe

i think the LAST COUPLE OF LINKS WILL ANSER YOUR QIUESTION

Your print head may be damaged. You might consider replacing it.

Canon suggests pulling the ink wells and also pulling the print head and then reinstalling the whole assembly. They consider this a reset. It is also suggested to replace the printhead which the ink cartridges are housed in. I have done this to remedy bad printing and am considering this $50 purchase as I am dealing with "wrong cartridge" message also. Some have said replacing the printhead remedied this code problem. BUT, i did read one person who said this did NOT work. Right now I am debating whether I should put $50 dollars more into this machine....although this printer has been excellent and many agree.
Comments: Apr 17, 2010 - As a follow up I did fix my "Wrong Cartridge" message by replacing the printhead, I worked and worked at cleaning the old one but finally gave in and anted up the $50. This fixed it! Long live DIYers!

Replace the ink
cartridge(s), or press the
OK button.
When selecting to press
the OK button, ink may
run out during printing.

I have the identical problem. After talking with the Canon Service Center here in Arizona, they stated that the problem is with the Printhead, not the ink cartridges. The choices are to buy a new Printhead, which are very hard to find now, or buy a new printer. I found one last Printhead in Tucson, which I can purchase of $50.00, and install it myself. Otherwise, the Service Center can do it for the price of the part, plus $65.00 labor.

Seems like the logical solution is to buy a new printer. The PIXMA MX330 is $99.00 or the PIXMA MX860 is $199.00, which are similar replacements.

I am leaning toward purchasing a new printer. We've had the MP730 for about 5 years.

That message means that you need a new printhead, the holder where your inks go. the part number is QY6-0064-000 around $40.00. easy to change yourself, instructions are included.

Keeping an order when installing printer cartridges is not necessary.

You can even replace just one cartridge and this would make no difference.

To replace all cartridge you usually start from the right side one and keep following, as it is easier to extract cartridges.

Follow the whole procedure from manual below, under maintainance>>Ink replacement.

Even with new cartridges sometimes the pc board that is attached to the cartridge can get dammage,replace the faulty cartridge.

All files on my website are only there for a limited time

I went to the Canon website http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&tabact=SupportDetailTabAct&fcategoryid=238&modelid=9035 and typed "Wrong Cartridge" in the search portion for the MP730. It listed detailed instructions to remove all ink cartridges, raise the lever to the right on the carrier, and then remove / reseat the "carrier". After that I replaced all cartridges and printed the alignment page. All is working, now.
