Re: mp 7500

Is it nothing to do with the print driver setting? If you print the image off on something else and then copy it is the result the same?

Re: mp 7500

munkeh,yep even in copying you have to lighten,if you use auto density its dark,i,ve noticed when i print test patterns a potion is dark,could it be the laser sync?

Re: mp 7500

You're using the "photo" setting, correct?

Re: mp 7500

Its the Laser diode assy. had this numerous times on that series. good luck on a couple of occasions I had to change the bcu shortly after replacing diode due to sc220 at start up. The laser will definately fix your dark copies. good luck

I don't think it's the laser unit. When there's something wrong with the laser unit (synchronizing errors, mirror motor errors) you will see laser unit related SC-codes appearing immediately. I'm sure it's printer driver related like Tonermunkeh and Jomama mentioned.

Re: mp 7500

Eric I can just about guarantee its the laser unit. I saw it at least 5 times I use the Katun test pattern and the surveyor face is almost pitch black.
