I'm assuming you've already verified that the carriage isn't binding, by trying to move the print head with the printer turned off, so we'll skip that step. If the carriage is moving, and suddenly stops, with a continuous error bell, it's possible that there is something wrong with the head positioning electronics. The motor that moves the print head has an encoder wheel on the back of it, which of course is monitored by the logic board. I would GUESS that if the printer doesn't see any feedback from the encoder, that it would stop the print head, and turn on the warning bell. I have one of these at home, with the classic "head slam" problem, which is also related to the encoder and/or electronics. It will print, but when returning to the left-hand side, it will start with a gentle tap while it's printing, then a bit louder, then a bit louder, as the carriage slams harder and harder up against the left stop plate. Finally, it stops, and the bell sounds. In this instance, it's losing track of where the print head is. I haven't had time to isolate the problem myself, but it sounds like you're having problems along the same lines. I would check the connections to the encoder wheel. . . the encoder wheel itself, (sometimes they get dust / dirt inside the enclosure, which interferes with operation), then the infrared sensors, and related circuitry on the board.
