Question about Canon PIXMA MP210 Photo All-In-One Printer
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
