hello! i have a question. i must change devs on some 8 series machines. does the black dev fit on color dev slots as the previous 4 series?

coming back again with solution. unfortunately the sys board is fried. thanks all for the help!

thanks for the aswers. i have a same model donor machine in service. swapped power supply and HV board, tried with all consumables out of the machine ( iu + fuser) and all doors open. nothing...

hello! just got a call from client that on powerup the machine goes to 2/9 booting steps then reboots, again 2/9 and reboot. cannot acess any mode for update, 08 menu etc. swapped memory ram and hdd...

thank you for that info, i used that a lot and works. but how about 8 series machines? i have searched all forum, didnt find anything. i am 99% sure that will work, but is there anyone done it?

if you changed all that and still you get jams 1st check if the door not closing good. try to print while you press the door against the machine or clean the vertical rollers in the small jam doors...

Looks like it was way off and was interfering with the ruler attached to the platen glass. Copied numbers from another machine and problem gone. Then I did a fine-tuning from there. Thank you all

If I raise the adf on the right side enough that don't actuate the sensor it works but it's messy because it don't start the procedure to read the platen glass if there is paper. It only works as it...

nah I am far from it. All boards that reference to scanning are replaced but no avail

As I said I already replaced scanner board and lens board from other working machine as Konica suggested but it's the same thing. Tomorrow I will contact them again since there is no other option...

Nop. No scanner board no lens board from other machine. Same thing.

That's right it works if I remove the reed switch because it don't enable the paper size detection. But that's not right. I am now replacing ccd and scanner board to check

It's a leasing return machine with low meter. Tried table 1 and 2. But table 2 is for machines with 2 sensors on the right. The only way that it works as supposed is with the platen glass removed....

I used 2 different adfs platen glass and slit glass from other working c258 machines to check. I done all the sane procedures. Now I am in the insane spectrum

Hello everyone! i have a c368 with the original left on glass when i lower the adf. what i have done so far

the machine has only 1 original sensor for a3 in the right side of the platen glass...

I think it needs thickness more than 1 paper. Try fold it 2 or 3 times

yeah i am aware of that. i just ask if there are parts so i can do it in my office and just go to customer and plug and play instead of swapping the covers on field

hey. have anyone found spare parts for the color drums holder-spacer so i can add black drums on color unit but build them in the office and not in customers office?
