I've got an older Canon G3012 printer that hasn't been used in about 3-4 months, and now it refuses to print anything. I've been proactive and tried several things to troubleshoot the issue:
- I performed a deep cleaning using the LCD display by pressing the 2 and 3 buttons.
- Unfortunately, it keeps showing a P08 error.
- I've spent hours researching printer mechanics and attempted to warm up the ink pipes inside the printhead (though I'm not entirely sure what they're called).
- I'm starting to wonder if Canon is practicing planned obsolescence with my device.
- Out of desperation, I even wiped away dust from the printer's exterior.
I really need my printer to work again and would love to avoid buying a new one, especially if I might end up in the same situation after a few months of not using it. Any suggestions?

It sounds like the printhead nozzles might be clogged, especially since the printer's been idle for a while. This can happen when ink dries inside. If you aren't using a printer with auto-cleaning features, it's a good idea to print something at least once a week if you can. Also, think about getting a new ink cartridge, but I'd recommend going for compatible ones instead of the original - they're often a lot cheaper!
I feel your pain! Leaving printers unused tends to cause issues. You might have dried ink that's hard to clean. If you ever decide to get another printer, consider a laser model next time—they're generally low-maintenance and don't have this sort of problem.
The P08 error typically indicates an issue with the ink tanks. Make sure they're filled with ink before trying any fixes. Try this: turn off the printer, then turn it back on to reset it. Next, press the settings button and then the '+' button ten times, followed by the black copy button. It should start the ink flush process, which usually takes about ten minutes, and hopefully, that resolves the P08 error.
First, check your connectivity! Since you're using Windows 11, make sure the printer is properly connected through USB, Ethernet, or WiFi. Have you managed to print a manual test page? It could help identify if the issue is with your computer or the printer itself.

I printed a test page, but unfortunately, all I got was a blank sheet. No waiting time either.
