    My problem is similar. I have new ink in the tanks. All lights are red. When I close the lid, the red light on the yellow ink goes off. I've tried re situating the tank, cleaning the electrodes, adding a drop of yellow ink from a refill kit, but nothing helps.

    I have the same problem. It started after I changed the Black cartridge, but now it thinks the other three are in the wrong place or empty (Error U072), but they are all full and in the right slot. Have re-set them several times and cycled power on the printer, but always the same. Now I get an Error 5100.

@jrad, caboos:

Please check the black cartridge: Mayby the chip of the black cartridge has an error. Had similar problem with Magenta in stead of black. Exchanged Magenta, now it works.

Answer Part 1 of 2

An error has occurred in the printer. The number of flashes indicates the type of error, as outlined below. Check the cause and take appropriate action.
Two flashes: Out of paper or paper feed error
Reload the paper correctly and press the RESUME/CANCEL button.
Three flashes: Paper jam
If paper has jammed in the printer, clear the jam, reload the paper in the printer correctly and press the RESUME/CANCEL button.
See Paper Jams
Four flashes: Ink tank is not installed properly
Open the Print Head Cover and check whether an ink tank is installed. If an ink tank is installed, push the button of the ink tank, and reinstall the ink tank properly.
Five flashes: No Print Head installed, or Print Head failure
Install a Print Head.
When the error continues, contact a Canon service representative.
Eight flashes: Waste ink absorber almost full
Ink used for cleaning is absorbed in a waste ink absorber placed in the printer. Eight flashes indicate that the waste ink absorber is nearly full. Press the RESUME/CANCEL button to cancel the error so that you can continue printing.
If this error occurs, replacement of the waste ink absorber and maintenance of the printer are required. Canon recommends to contact a Canon service representative as soon as possible. Once the waste ink absorber becomes completely full, it cannot be printed until the Waste ink tank is exchanged.

Nine flashes: A specified period of time has lapsed without receiving a response from a digital camera or digital video camcorder / The digital camera or digital video camcorder connected is not compatible with this printer

My ink lamp does not light red-pixma mx700

Have you installed the print head? It's a separate item in a foil colored sealed package. It must be installed and locked in before inserting the ink tanks. If you have done this and still get no lights on the ink tanks, there is something wrong with the unit itself.

Ink cartridge (not) installed properly

For the Canon iP1800 printer are you sure you're using the 30 for black and 31 for color?

And make sure they "click" when installed. That should confirm that they're nice and tight in their ink compartments.

Besides that, maybe reinstalling the printer drivers could do something?

Error code 510

If the error code is actually 5100, this is how you fix it:

Open the paper output tray.
Lift the scanning unit (printer cover) completely. (The print head will move to the replacement position.)
Open the inner cover.
a. Do not try to manually move or stop the Print Head Holder.
b. Do not touch any metal parts.

Press down on the ink tank until a click is heard, thereby making sure the ink tank is seated properly.
Make sure that the ink tank is inserted in the slot that corresponds to the ink tank's color.

Ensure that all the ink tanks are installed properly and the ink tank lamps light red
Ink Tank Lamp
You can check the status of each ink tank according to the way its lamp flashes.

- On: The printer is ready to print.
- Slow flashing (at about three second interval): Ink is low. Prepare a new ink tank.
- Fast flashing (at about one second interval): Ink tank is empty, or the printer is not ready due to an error.
- Off: An error has occurred and the printer is not ready to print.
Close the inner cover and the scanning unit (printer cover).
When closing the scanning unit (printer cover), be careful not to jam your finger.
When starting printing next time, the print head cleaning launches automatically.

If you haven't installed ink recently -- then you are out of ink and that is why you ink out light is flickering.

Hope this helps.
Good Luck.
