Hi
I found this in a forum you can try it see if it work for you.
To reset waste tank full error in MP730.
1. Hit the "menu": Key
2. Hit "Copy" Key
3. Hit "#" Key
4. Scroll thru the menu headings until you come to "Test Mode" - 12th heading
5. Hit the "3" button- this will bring up Eprom Clear
6. Hit "0" button
7. Hit the "Stop" button
Also I found this.
First Clean and Dry the Print Head:
I used a cotton swab dipped in 70% isopropyl alcohol (rubbing alcohol). Do not use too much alcohol.
Then dry the heads, again using dry cotton swab. Be careful not leave any cotton threads on the print heads.
Then I padded dry the spongy Ink Absorbers (one for black ink and the other for color ink) using
Separate cotton swabs for each absorber. Do not displace the absorbers. Or you can replace the ink absorbers at this point if you do not want to pad them dry.
Then Proceed to the Waste Tank Reset procedure below:

Then the display changes to:

5. Then Press the "3" button and the display shows:
8 – 3 : EEPROM Clear
*** the display scrolls to [0] : INK COUNT
[1] : 2PURGE FLAG
6. Press "0" button – for INK COUNT

8. Press Off then On to set new changes.
9. Printer feeds a blank page after it is turned on again.
This should Reset the printer and remove the WRONG CARTRIDGE error and save you a few dollars.
Please all I ask is call back and just gave a vote, it will gave me some satisfaction to know am helping some one, so I will keep on helping.

Thank you! Thank you! Thank you! I've done most of the pressing tests over and over for weeks.
Finally today I followed your instruction for most part. I played around somewhat with all the instructions but when I got EEPROM after pressing 3, I followed your directions pretty much, after hitting the on then off buttons the light went off. Did most of it when saying wait please and the stop several times followed by the on off and it finally stopped the flashing light and it was in copy mode again. I then went back to write down what I did and the flashing light started again so fiddled around some more and got it off again. That is why I am not sure what I did for fear of it resuming the alarm light again. Rather inconclusive on my part, but none the less it worked!! Thanks again! tessalee2
