As long as the printer was shut down properly and was stored in a controlled (steady) temperature, you shouldn't have any issues besides it doing the cleanings. It may also check that the maintenance tank is good to use.
I've checked with our Canon rep and he's had his iPF6350 on idle thru a winter and nothing was needing to be done after he turned it back on.
If you do have questions or get any errors, you can check with Canon's tech department (800-423-2366) or we can look into it for you.
Thank you for your reply.
Thankfully it was shut down properly, and it was stored in a more or less in a controlled environment, so i'll get new ink and a printhead.
thank you again.
