When the Epson all-in-one device that Steve bought for his mother failed, the error message indicated that the ink pads were worn out. Simple enough: Just replace the ink pads, right? Wrong. When the printer decides, somewhat arbitrarily, that the pads are worn out, that puts the whole device out of commission. It could still be used as a scanner, or to send outbound faxes. But not when the ink pads are worn out. When that happens, you have to throw the whole thing out and buy a new one.
