Re: machine does not copy

LSU Error occurs when your printer printhead is damaged. Change your printer printhead, the printer will be ok.

LSU Error keeps showing

LSU stands for Laser Scanner Unit. Depending on the model this should come up only if the services used required scanning such as copy, fax sending, scanning.
nevertheless if this is a continuous message you might need to check the connectors within the scanner which I advise an field call.

LSU error message

Remove the jammed paper. Unplug the printer from the mains and PC. Inspect the rollers, etc for tiny paper piece(s) that may be stuck, or other debris. Try to clean rollers and make sure they are dry.
Keep printer unplugged for about 2 minutes and replug and try a test print.
Also make sure that you have waited long enough for the printer to heat up before giving a print job.
Finally, it could be an issue with the paper sensor. If this is the case, you will probably have to take the printer in for servicing..

LSU ERROR MESSAGE ON little screen when photocopying

The LSU error stands for Laser Scanner Unit error. The probable cause/s:

The Polygon motor in the LSU does not rotate.
The LSU’s laser beam is functioning properly.

What you can do:

Try to unplug the machine for a couple of minutes or maybe a little longer and then plug everything back in. Power on and then test.

LSU error code

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.

Printer Problem

What model printer is this? The C2424 does not have a laser.
Are you 100 percent sure it is a model C2424?
There is no LSU status code for that machine.
