Query: Great, fast tech support. Very good product

I've had a problem with my MP530 and a malfunctioning ink cartridge. I e-mailed tech support, and they responded within two hours and are sending a replacement by 2 day UPS. While I am annoyed that my new printer was not working properly, I was overwhelmed that tech support worked so quickly.As for the printer, I have been very satisfied. I use it mainly for fast printing and scanning, both of which it does very well for my purposes. Very satisfied with my purchase.
