The Ink may have run out.
The function for detecting the remaining ink level will be disabled since the ink level cannot be correctly detected.
If you want to continue printing without this function, press the Stop/Reset button for at least 5 seconds.
Canon recommends to use new genuine Canon cartridges in order to obtain optimum qualities.
Please be advised that Canon shall not be liable for any malfunction or trouble caused by continuation of printing under the ink out condition.
NOTE
If the function for detecting the remaining ink level is disabled, the ink cartridge
in grey is displayed in the remaining ink volume screen on the LCD.
I dont know why Cannon persist wuth there stupid messages by morse code,
E 7 means that a sensor has detected an incorrect ink cartridge
Options to fix
1.Check the ink cartridges are correctly installed
2. If you have recently replaced an ink cartridge with one from a supplier other than Cannon feplace the cartridge with a Cannon branded prosduct
3. If everything looks ok then try powering down the printer, unplug wait 2 minutes for all residual power to drain, then power up to see if the printer has resolved the problem, this just resets the sensor which reports the error but it often works as the sensors are the most likely part to give intermitten faults
If after you install the cartridge you get a yellow light and error message:
“The following may have run out of color. The function for
detecting the remaining ink level will be disabled since the
ink level cannot be correctly detected. If you want to
continue printing with out this function, press the printer’s
start button. Canon recommends using new genuine Canon
cartridges in order to obtain optimum quality.”
Do not click “cancel printing”. Press printer start button
to start printing. This action will bypass the ink level
detection from the recycled cartridge. It will not damage the
printer! With a recycled cartridge this action needs to be
done one time.
A full recycled cartridge ink level may not display correctly.
It may show empty.
If you want to check the ink level, you can do a “Nozzle
check” by follow the directions below:
Go to menu File select print click on “Property” click
on “Maintenance”
Click on “Nozzle check” to print out the color check.
Click on “Cartridge Alignment” to align the cartridge.
