SAMSUNG C8380MFP

[lenovos]

Hi I am not a Samsung tech but I was sent out to look at an c8380nd. Customer replaced yellow toner about 1 week ago yesterday they got a message that said yellow toner worn replace. Today I took up a new yellow toner and installed it (OEM) The machine kept telling me to install yellow toner. Would a bad toner add motor cause this?

The yellow toner that I removed was just as heavy as the new one. When the motors fail do they give an error code?

Thanks in advance. Like I said I am a Sharp and HP tech.

I found a service manual and was able to eliminate the toner add motor it did turn using simulation. I replaced the yellow imaging unit and that seems to have corrected the problem. I replaced the blown chips on back of yellow toners with aftermarket chips.
