What should I tell Canon support if I contact them about the 5B00 error after a reset on my G3000?

When contacting Canon support, clearly explain that you received the 5B00 error *after* performing a reset. Detail the steps you've already taken to troubleshoot the issue (deep cleaning, alignment, ink cartridge reinstallation). Provide the printer's model number (G3000) and serial number. Be prepared to describe the circumstances surrounding the reset – why you performed it in the first place.
