having trouble with my dc4sx sensing media. just put in a new roll of media went to run calibration and it shifts the media left and right and usually starts to print with the media crinkled against the hold down. messing up the left edge of the media and binding the carriage when it passes over. tried cleaning the sensor but no luck. any ideas tech support is closed when i get to my machine so they are out of the question. tried email and I Get a call tech support. sending the machine in is out of the question as it is in HAWAII.
