Question about Computers & Internet
LSU is your Laser Sending Unit.
Try turning your computer off and then back on. A good cleaning sometimes solves the problem, but as I don't know the specific model I can't give you specifics on how to do that.
If it continues you may want to find out how much it would be to repair it. that may be cost prohibitive. Ink jet printers have become very inexpensive, so replacement may be your best option.
