I have a problem of system error of copier ir 2000. how can i solve it?

can You be specific by mean of which system error? Like E100? E000?, E001....

Few examples of most common errors:
E100 - Laser trouble - change the drum unit ( complete drum unit )
E000/001 - fixing trouble - try to reset the error under service mode - procedure: press MENU and #, with > key go to CLEAR and OK, find ERR and OK, turn off and back on - if it helps you solved the problem, if not you need to change the thermistors or the fixing lamp, because you have low/high temperature problem.
E019 - waste toner full - remove the drum unit and open the corks on top of the unit and empty/vacume waste toner out.

Hope that helps!

E100 is laser related error.

You can try to reconect the conectors on dc controler board, and on laser unit, clean the laser, check if the laser shuter is broken.
If notthing helps the next step would be to chnage the laser unit and/or dc pcb
