i have a big problem with this machine. i have changed drum, drum blade and developer new but copy is very bad, how can i fix the copy ? and when i take a copy 1. cassette its working much and gives code E-89-2.... and who can give this macine's simulation codes and setup ?

Manual says it's the SCB ( System Control Board ) but if I'm not mistaken E89 codes often are generated when the print controller doesn't boot properly, this can be because corrupt firmware in controller or bad main body HDD. I would try removing the print controller if you have one, and doing a HDD Format if you have one.

As far as your quality issue, if you performed L Detect when changing Dev and Drum Ch wire and Blade have been done all should be well, tell us more about the quality, too light? too dark? streaks? Just saying bad quality doesn't give us much to go on.

these are the copies

That looks like a developer issue, turn the dev by hand and see if you have any voids ares on the mag roller, make sure mixer bushings aren't seized.
