How long can you store the paper and ink. and does it have to be refrigerated?
Also my canon printer 3000 is blinking orange and green anyone familiar with this?

I used to have a canon and can't remember what the blinks mean but if you look in your manual it should say. Look under troublshooting, I believe. It might be a paper jam or something. As to your other questions I'm not sure.Sorry.

I store my paper in the plastic ziploc type bag that it came in and I leave my ink cartridges in the printer. I have not had a problem with clogging.I think the blinking may be a paper jam.

Neither the inks nor the frosting sheets need to be refrigerated. You should never refrigerate the inks but you can refrigerate the frosting sheets if you live in a hot/dry climate and think it would help keep them from drying out. Always keep them sealed airtight.

You can troubleshoot the blinking online at the Canon site.

Thanks everyone, I want to figure out the printer problem and did not want to lose the paper or ink due to improper storage.
I think i may have gotten burned on this printer. the printer head does not move to the middle. i have never gotten past installing the driver.

Oh that stinks If you purchased your printer new and recently, the warranty should still be valid. Call Canon for a replacement. Hope it all works out for you.
