I wouldn't try it unless it can be kept completely flat - the maintenance tank is one potential issue, but the bigger problem is that Canon printers use sub-tanks in between the tanks and the head. It's what allows them to drain cartridges completely, and avoid Epson's complex pressurized ink system, but it's also the source of leaks. I saw one of these ruined by a Level 2 move that should have been a Level 3 (significant stairs). Unless you have wide enough doors at both ends, and no real stairs (depending on what two or three entrance stairs look like, you may be able to keep it flat), you need to do a Level 2 or even a Level 3...
