Display reads E-7 03 error code


E7/03 is a lsu error. The LSU is the “printer head” of the printer. But instead of emitting ink, the LSU emits a laser beam, directing it at the drum of the toner cartridge. If replacing the lsu does not fix it it may be the mcu pwb, but most likely the LSU.

Have lsu error also.


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 ....

LSU ERROR shows in display panel


The LSU is the Laser Scanning Unit or "printhead". There is a mirror in there that spins really fast, if the mirror spins too slowly (bad motor, low voltage) it gives an error. Sounds like you would need a replacement LSU. Have the printer serviced.

LSU Error


LSU (Laser Scanning Unit) is a device inside the printer that create images on the drum.
If you see LSU Error on the display, it is indicating that there's a problem with LSU unit.

  • Unplug the power cord and plug it back in.
  • Check if the printer makes any humming noise.

If the problem persists or does not make any noise, LSU needs to be replaced.
If your unit is under warranty, please contact our tech support at 800 - 726 - 7864.
Otherwise, please find nearest Samsung Authorized Service center from the link below.
