Hi, My Canon MP210 printer is displaying E3 code. The colour light and alarm lights are illuminated constantly and black one is flashing. When opening the "lid", the cartridges do not align to the centre. I have tried resetting the printer, but to no avail. Any help would be gratefully appreciated! Thanks.

I have workaround for the empty tank issue:
- buy or borrow another not empty tank
- place it in
- start the printer
- it recognises the "new" tank
- turn off the printer
- put back the old, empty, but refilled tank
- turn on the printer
- print something
- it will pop up a dialogue window saying
"The ink level of the black/color tank cannot be
determined. The ink level determining function will be
disabled for the black/color tank.
If you want to continue printing without this function
press the Start button on the printer."
- Press the Start button on the printer and ignore the
button 'Cancel Printing' appearing on the dialogue window.
- The dialog window disappears.

You can print your refilled tank as many times you want from this time.

When you go to 'Printers /Canon /Properties /Maintenance / Printer Status / Ink Information' it says that the ink level measuring function has been disabled for: black [40] / color[41]. You can ignore this this message, the printer will work perfectly without this stupid function.
