#099. The job was cancelled. Perform the job again. An error occurred because the main power switch was turned OFF while executing a job.
Unplug and restart your printer

Sometimes power cycling your printer can resolve the issue. Turn off your printer and unplug it, wait 30 seconds, plug your printer back in, and then turn the printer back on. If your printer still doesn`t work, continue to step 2.

Common factors include driver problems, software issues, hardware failures and overuse.
I recommend performing a reset of the printer. While the printer is on, unplug the power cord from the printer and let it sit for 60 seconds. While the power is off, press the power button 5 times. After 60 seconds plug the power cord back in and power on the printer.
An E9 error occurs when the printer detects that ink system maintenance is required. An Ink System Maintenance page prints containing instructions to open and close the printhead access door to resolve the error.
You may face the “printer not activated error code –20/30” for different reasons. For instance, the outdated Windows OS, incorrectly working printer drivers, or not having the fill permissions of your account may lead to this issue. Besides, this error may also be caused when your printer device is not set as default.
With the printer powered on, select Setup . Select Device settings . Scroll to the bottom of the menu list and select Reset settings.
The printer supports 3 connection methods. USB, Ethernet or Wireless. None of them depend on or require a internet connection to function. Without internet, you will not be able to use any cloud based features like scan to email, but printing and scanning to / from devices on a local network is possible.
Connecting using a network key or PIN

If your printer doesn`t have WPS, you`ll probably have to enter a `network key` – a series of numbers and letters – into the printer using the function buttons and screen on the printer in order to establish the connection between your printer and router.

If your wireless printer isn`t printing, be sure to check your settings. Make sure your Wi-Fi is enabled, and then check to be sure you`re connected to the correct Wi-Fi network. You can often check your connectivity by printing a network configuration sheet by selecting this option from the printer`s display menu.
Printers can run reliably for many years and thousands of prints, but they can also malfunction or stop working entirely. Sometimes the reason is as simple as over- or under use. Many people don`t use their inkjet printers often enough and this can lead to problems with dried-up ink blocking the nozzles.
Do a hard reset on your printer. To do this you just need to turn off your printer, unplug for a few minutes and then plug the printer again. If that still doesn`t work, try turning the printer and your computer off, and then start it back up again. Try uninstalling and then reinstalling your printer driver.
It`s usually because the printhead inside your printer is clogged or dried out. Like with most printers, Canon printheads can clog due to ink or dust drying up and collecting in the nozzle.

Quick Fix:

The first thing you can do is remove the cartridge and try re-installing it to see if the printer will recognise it, if it will still not recognise the cartridge then simply hold down the stop button (this is the button with the triangle inside a circle) for a minimum of 7 seconds.
