this error code came from the LD unit which means the seconder LD is not synchronized on the machine but try to clean the mirror if it came agin the replace the LD board

Bad laser diode unit. It must be replaced and aligned.

kindly check if there is enouh developer in the unit .if there is check the glass covering the laser unit and clean it.
if there there is no developer then change it and the problem is solved

dsm 745 has more modification than1045 more comfortable less disputes little problem. technicians can see this difference there are more details but i expressed that dsm 745 is recently than 1045 good luck

Independente do modelo ser Dsm715 ou Dsm745 esse codigo corresponde a um erro na Unidade de Laser, mais precisamente com o sincronismo.
A primeira coisa a verificar nestes casos é se a Unidade de Laser está suja. Por vezes cai toner para o Laser e provoca estes codigos.
Se tiveres conhecimento tecnico saberás chegar á unidade de Laser. Se não tens esse conhecimento aconcelho a não mexeres (chama alguem que o saiba fazer).
Na minha opinião este deve ser o primeiro passo a dar. Deves fazer uma limpeza na Unidade de Laser.
Se não resultar replica para mim ou volta a colocar a questão no Fixya. Existem otros factores que podem provocar este codigo.
Fica bem!

West toner is situated in user manual.Thanks

These SC errors are related to the Hard disk.
Re - enter SP mode: Clear, 107 and press and hold Stop button for 3 secs.
Enter SP 5832-008 and press #,(Mail Tx data) to initialize the HDD. Then switch off and on the machine.
If still with error, replace the HDD.
Attention not to change any others SP modes - very sensitive settings!

Good luck and please rate me, thanks.

This is an SC error related to the laser unit.
Switch off and on the printer. If the error still appears, the printer has a defective laser diode or a defective Laser unit.
Please call an engineer to repair your printer.

Good luck and please rate me, thanks.
