Summary: Heavy, delivered on a skid, then didn't work. Got a persistent error about a toner cartridge that was impossible to eliminate. Documentation was superficial, not helpful at all, no telephone number to call therefore no alternative but to pack the thing up and return it.
Summary: It is difficult to adjust the color, I have to do it mostly in the printing program and then if I print the same page 6 times I will get different color intensities for each print. I had a Techtronic phaser before and it was very easy to use.
Summary: I ordered the 6180DN, but when the 6180N (no duplexing) arrived three days late (next day shipping? forget it!), I decided to try it out anyway. The set-up video did not work on my new iMac. The written instructions, however, were fine. But when it came time to print, it didn't.
