I have a CP760 that I use to make the occasional 4x6 print at home and late last year I bought 2 KP-108IN ink and paper packs.
While doing a bunch of prints I had to replace the ink cartridge and paper and on the next run the cartridge seemed to run out really fast - the printer prompted for a new ink cartridge, and when I pulled it out the marking on the cartridge indicated 5 prints as opposed to 36. From memory I think you get a little sample pack when you buy the printer so I guess someone screwed up during packaging.
I contact Canon customer service and after a couple of weeks or so they tell me they've sent me a replacement. I called about a week after this and I'm informed it's in transit. Christmas and New Year's comes and goes and I realize, "Where the heck is that package?"
I contact Canon again and they give me a tracking number, which I look up and the package has been returned to sender. I live in an apartment building and the courier they use is notorious for issues with deliveries to apartment buildings. Never got a phone call or any kind of notification that I had a package waiting to be delivered or picked up from their depot. I let Canon know and they overnighted the package before they got my email asking them to send it to work but they give me the tracking number this time.
I get hold of the courier company and tell them to hold the package at the depot - I finally get a chance to swing by and pickup the package last night. I open the box and find...
An ink and paper pack for card size prints (see photo). I guess Canon technically fulfilled their responsibility by sending me a replacement cartridge but now I'm short 5 sheets of 4x6 and also have 36 card sized sheets I can't even use without an additional accessory.
Don't think I'll pursue it any further but thanks for reading my rant..!
