Summary: I purchased the Canon MP510 in August 2007, my first Canon and first multi-function printer. It died this week for no apparent reason, having sat in the same place for about a year (34 mos since it was purchased). During its lifespan it 'did the job' of printing satisfactorily. I rarely printed photos, and when I did, found the quality well below that of my previous Epson printers. Even black-on-white printing was substandard. The MP510 is an ink-guzzler, too.
Summary: I bought this printer for my daughter attending and college and liked it so much I bought one for myself. Neither of us used it on a regular basis and they both quit feeding paper at the same time - about 1-1/2 years later. Very frustrating since we both had just bought new ink.
Summary: I am a Mac user and every time I switch functions on this printer (i.e. to scan/copy), it needs to be reinstalled on the computer or it won't print again. After 2 years of ink-guzzling use, it has developed an error message implying it has a paper jam. It does not. My only option, per canon, it to take it to be repaired for $80 since it is out of warranty.
Summary: I bought this based on the glowing reviews and my past love of Canon products. I was highly disappointed. The placement of the power cord is extremely inconvenient. It is hard to attach, falls out constantly, and the way it loops around to the back makes it nearly impossible to place it on any kind of shelf. if you're trying to conserve space and don't want a large printer out in the open, don't buy this and expect it to go into any against the wall apparatus.
