Re: Kyocera 5002i C7301 Toner Motor K Error

First, allow me to thank everyone for the advice and suggestions. However, being unable to locate any toner blockages, and having replaced the following parts, Developer Unit, DR-6500 Main Drive Unit, Waste Toner Box, Toner Supply Drive Unit, and Feed Image PWB, I've come to an impasse. After all these parts were replaced, and no toner blockages found, I have to wonder why I'm still getting prints with print missing, light, or washed out.

Also, since I started this repair, and even after replacing said parts, not once has the machine shown any indications that it's adding toner, on the Op Panel.

I replaced the developer unit a few days ago with no positive results. Also, I replaced the Main Drive unit, Waste Toner Box(that's on the inner side of the Main Drive Unit.)
New Feed Image PWB, as well.

I know it's a old post but for the knowledge base, this is what that toner duct thingy looks like. We have a machine that just threw this code. New DV didn't fix it but the old DV unit had 730k on it (sales said it was getting upgraded, apparently it didn't ). The DV unit was kaput, im guessing it backed the entire system up. Likely that toner pipe is packed full of toner. We are heading out to replace this unit. YC19 Pin 2 on the feed image board should cycle 24 volts when the machine is adding toner from testing on a machine in the office. Not sure if the motor can take out the board if this unit locks up.

Im assuming this is the sensor that detects if a C7301 is occuring.

Motor and pipe. In the middle is a LED and sensor im assuming is the level sensor.

Had similar codes with old dev units 5 year old plus just randomly decides no toner. I tried many ways to get them to return to normal but I usually just vac out toner hoppers and replace dev units. I've also seen the foam sponges get torn and block the inlet.

Also had had a transfer belt cause it weirdly as well.
