I would highly suspect a defective toner. What happens if you put the old toner back in - - do you get the same error? If you don't, then replace the toner. If you continue to get a lsu error, then your Laser Unit has a toner spill on the glass, or has gone bad and will need replaced.
First just turn it off for ten minutes and then restart it,
There is a fault in the LSU unit. 1. Use EDC mode to test the HSYNC signal and LSU Motor. 2. Check the Harness connected to the Engine Controller and LSU. 2.

Do you have the old cartridge? Because the message you are getting makes no sense if you can copy and not print. The chip on the cartridge may be corrupting the machine software.
I will explaine why I say this. LSU fault, is a failure of the laser unit within the printer/copier. If it had failed, you should not be able to copy or print, The machine should not function. The laser unit is what makes the image on the drum. So neither print or copy should work if that was a true LSU code.
Did you purchase a cartridge made by another company other than Xerox? If so try returning it.
As I say, an LSU code should make the machine totally unpoerable, not partially functional.
I would try the old cartridge if you have it to see what happens.
Let me know if you have tried swapping cartridges and I will look into this more for you.
if it's a vertical line in scanned pictures, it's probably a dust bunny on the scanner head, if it's only on printed pages, it's probably a dust bunny on or in the laser assembly or between the laser and the photosensitive drum. if cleaning doesn't get rid of it, you could have a defective scanner head or laser assembly, or a scratch on the photosensitive drum.
