In between cartridge changes, the MP150 does a more-than-reasonable job for home use. This can be particularly annoying if one cartridge runs out a few pages after you've replaced, and aligned, the other-as happened during my tests. Worse, you have to align the heads every time you change a cartridge. I never actually noticed those labels, however, because they're easy to miss.Ī more important issue is that you have to align the print heads by printing an alignment page and then picking the right settings to enter into the driver-something that almost no ink jets force you to do anymore. It turns out that the cartridge slots are indeed labeled B, for black, and C, for color, inside the printer to mark their respective positions.

But until you've inserted a cartridge at least once, you won't know how to tell when it's inserted correctly. I did discover through trial and error that if you put either cartridge in the wrong position, you can't snap it into place. To begin with, it's difficult to figure out which ink cartridge goes where. Unfortunately, though, there are a few snags to watch out for. Simply connect the power cord, install both the black and tricolor ink cartridges, load the paper, run the automated setup program, and connect the USB cable when prompted.
