High Voltage Transformer = HVT ( the board that gives you your charge / bias etc... )
You can vac the dev unit, but you must keep your fingers on the mag roller to ensure you don't cause a static shock to damage the auto toner sensor.

Ahh. okay. That's what I'm suspecting, maybe I damaged the ATDC sensor. Thank you for the info. By the way, is there any calibration or adjustment in HV where I can play with? I cant find any service manual in the net lurking around just the old models of toshiba. And where is the HVT located in the machine?

Re: eStudio 2050c/2550c Series

There's no adjustment for the HVT that will make any difference (there are some codes i once found, but they didn't make any difference)
The HVT is at the bottom right of the back of the machine (behind the back cover)

Have you tried clearing the gamma tables? (i guess not if you haven't got a manual) 08 - 7300 initialize
We had one where the image was similar & it needed the firmware re-loading but using the hardwear jigs rather than usb.

Thanks I will try that tomorrow and will inform you whatever happens. In our company, I'm the only one who uses the real manual of the machine and do some networking and firmware flashing for some brands which do not requires hardware jigs. They are using intravia that is not complete and sometimes not explained clearly. As a sign of gratitude, if you need manuals of other brands, I have some to share.

Hi mckinley, I found that the problem was in cyan and magenta developer unit. When I replaced it with another machine, the copy becomes good. By the way, if I'll request for the developing unit, does it comes with developer inside? Or it is separate? If separate, is there any calibration? Like 08-2000? Thanks for the support.

Re: eStudio 2050c/2550c Series

I think you have to order the dev separately ( there's no picture of a dev satchet or bottle on the online parts site anyway, which there normally is if you get one )
05 - 2002 = M / 05 - 2003 = C

I just had one 2 hours away where the transfer belt bushings had seized & toner had vibrated all over the place, atleast it's sunny though so i can't complain

Regards.

Thanks..Well I guess 05-2001 for Yellow and 05-2004 for black? but that is not important for now. Still I have some confusions whether I have to change the whole unit or the developer only will solve the problem. I haven't seen any damage in the developer unit.
