SOURCE: Reset ink level on CANON MP 140 PIXMA PRINTER

How to reset the Canon MP150 after a refill (Step 10 concerns refill; instructions below the steps):
Method1 (Safe Factory Method):
1) Disconnect the printer’s power outlet
2) Press and hold the power button while connecting the power outlet back.
3) While still holding down the power button, press the reset button twice.(red circle with a triangle)
4) Release the power button
The printer takes about 10 seconds to show the number 0.
5) Press + to change the value from 0 to 1.
6) When this value is 1, press colour button; this will light up two leds.
One is for plain paper and the other for photo paper. At this point is feed the printer with paper.
7) Press the power button twice and the printer will print a some stuff (if it doesn't print by itself, then press the "color" button once and the test sheet will print). Don’t worry much about the printed material. I got some stripped lines and some numbers. I believe that my colour cartridge is clogged which is why I got the green strips.
When you print this sheet the value in the display returns to zero.
8 ) Open the printer cover cover (not the scanner cover) and remove the cartridges. With the printer still open, disconnect the power outlet.
9) Close the lid and turn on the printer.
10) Refill cartridges and place them back in their nice little abode in the printer.

This worked for me: hold down the stop/reset button til the indicator light near the on/off button starts cycling.  The color ink orange light remains on but I can still print black and white and scan as normal.  Good luck!

SOURCE: refilling cartridges

For that printer: there are 4 color and 4 black cartridges BESIDES the #31 photo cartridge. Lexmark has made it so you MUST either, throw away or send to them, the 36 and 37, the 36XL and 37XL. The printer will never again recognize them after they are removed from the printer...
However, the 36XLA and 37XLA AND the 36A and 37A as well as the 31 Photo may be removed from the printer, refilled, and reinstalled.

I have seen some forums that say you can but a piece of BLACK tape, across the bottom row of contacts on the non-refillable cartridges....I believe there are 4 to 7 contacts across the bottom row only.....and the printer will still give you a message that it needs ink.....but it WILL print. I have not tested this theory yet though. I have just gotten the first message saying my black ink is very low.

Hope this helps and I think Lexmark Corporation Sucks for tricking people like this. (This printer comes with the NON refillable cartridges as default, but I did NOT see in the documentation that it couldn't be refilled. Nasty people........:(

Good Luck~~! [email protected]

I found these instruction at out-of-warranty.com They seem like a possible solution.

Steps:

1. Press Cancel and Power, at the same time.
2. Then, the Unit will ask for a Key Combo, press blue, green, gray buttons (in order) for this.
3. “Support Menu” should appear.
4. Go to Resets menu and use the semi-full reset.

The ink cartridge is most likely chipped & you would not be able to reset the ink level. Purchase an original or a good compatible cartridge. Refiling newer cartridges is not a good idea.
