Howdy folks,
Had a 6053 go down on Monday, message on the screen showed all 4 toners needed to be installed. The customer had changed a toner on Thursday and the machine worked fine for the rest of the week and was down Monday morning.
I couldn't find anything in the book on how the toner detection works and i expected it would of told us which toner is not installed. It doesn't.
The little fins on the back of the toner that i assumed were just for keying the toners to certain machines, they are more than that. In the back of the hopper unit is metal plates that those fins push apart. If one toner is missing or one of those plastic fins is missing, it completes a circuit and tells the machine that no toners are present. The way they built this thing, its all or nothing on the detection. It never will tell you just 1 toner is missing. On the color machines there are jumpers going across to each toner detection plate for the inner and outer plates.
There are 3 wires that connect to those plates, the yellow/black wire are in constant connection, if you unplug the connector on the Feed image board you get a 7320 error code. I think if the yellow/back wire looses continuity thats its protection that the connector is unplugged.
If the red/black wire has continuity that means a toner is not installed. When the toners are installed it splits all the plates and breaks the circuit allowing the machine to start up.
My machine had a broken fin on the yellow toner. Not sure why it worked for 2 days then quit but it did and i missed the broken fin on the first visit. It wasn't until i got back to the shop and figured out how this system works i understood what likely happened and how to check it.
If you pull the connector of the feed image board, YC12 pins 6 & 8 are the black and red wire, you can measure continuity and pull the toners in and out to test. Pins 6 & 7 should always have continuity.
Picture is from a toner unit i had sitting on the shelf from a old 4002 so it doesn't have the jumper wires or extra plates.
Hope this helps some on in the future, tech support and every one i called had no idea how this actually works.
Under the sticker on the top of the toner is a black chip, thats what the RFID board reads and tells you toner levels. If you remove that chip i think you can install any "Speed" of toner that will actually fit. IE 2554 toner can go into a 3554 just no toner level detection, low toner alert and a warning your using knock off toner on the status page.
