Yes. I have also found that they can be quite good over the phone in providing you with trouble-shooting assistance or answering questions when you are stumped. With that said, GOD HELP YOU if you actually need a service visit from Canon. They are quite good at that, (well ... they actually farm the service out to Pitney Bowes here in the US ... so its not really Canon), but at a price! I just went through it this week with my 8300. Hold on to your hat ... or I should say wallet: A service call is $1,500.00 (plus sales tax). If you don't have an extended warranty, you are basically "between a rock and a hard spot" when it comes to a service call from Canon. All said and done, when you consider the 2 ink cartridges that also got used up in the service, it was closer to $2,000.00! Now, my machine was only a year and half old, with light to moderate use. In my case, they had to replace a relay head PCB, the print heads, and the maintenance cartridge. However, if it would have been something as simple as a belt or ribbon cable, it still would have been the flat $1,500.00! At that point: New machine vs. Service Call? Quite a decision. If I didn't have jobs / orders that I had to get done this weekend, I would have simply bought a new machine with all the specials and discounts that are being offered at the moment.
Here is the deal with Canon service: While you may be lucky enough to find an independent service company or technician that knows your machine, getting the parts is an entirely different story. Canon has tight grip on the parts. Canon sends you what they think you will need in terms of parts directly to you. Pitney Bowes didn't have any parts when they showed up to do the work. I actually found several independent service technicians who said they could work on my 8300, but they said it could take them up to week or longer to get the needed parts from "back-channel" sources.
So, while they may great on the phone, just keep in mind: If you need a service call from them, be prepared to bend over, grab your ankles, and take a deep breath.
