LSU is your laser assy. Sounds like you have a major problem. Laser usually needs replacing with this fault.

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. Check the Harness connected to the Engine Controller and LSU. --> Refit the harness or replace it if it is damaged.

If the problem still happens call a repair tech.

hi
the cover that pritect the laser unit is closed; the release lever of LSU is not actuated; try to open the front cover and look inside is the lever ok , if broken block it with plastic parts to get the LSU on. if LASER beam does not reach te drum unit you have a blank page because the drum was not scanned.

I have same problem too. Did you find a solution?

Even though the toner was shown at 1/2, I had the fax machine operator install a new cartridge. Problem solved!

Hi ...

LSU stands for Laser Scanner Unit ... you normally get 2 different kind of errors with LSU ...
LSU Hsync or LSU Motor Error ...
If you get this error, it means that the Laser Scanner Unit has gone bad and the only way to get it fixed is to get the printer repaired ...

Cheers ....
