c3002 "add toner" new developerbox

[djteck]

Hi Mark et al

I see a lot of the 02 series so I see a lot of this problem. I believe there is a bulletin detailing the procedures everyone is discussing here - good procedures to follow.

Because I see this so often, I carry the toner sensor board and a toner pump (K). Easy to replace and saves a lot of time.

Had one today that turned out to be the DV unit, but its more likely the pump or sensor board. I always clean out the hose and the valve that feeds it, since they can get clogged. I keep an eye out for toner dropping in back where the toner hose meets the valve.

Non Ricoh toner is often involved. Also have seen Ricoh toner misread as 3rd party as a symptom of this issue. I have not initialized the DV as part of this procedure, unless I was replacing the DV unit.

Hope this helps.

If it saying loading toner then replace it will be the pump if it says not toner it would be toner end dection sensor but only on cym no sensor on bk.

Also check see if dev clutch is turning pull out dev unit if toner around the entrance of dev assy and in machine it will be the clutch

Dear mga.
With all due respect sir, but i can't make head nor tail of what you are writing.

What toner colour is it calling for? all 4 pumps are different but as a test you can swap them around to help troubleshoot.

Swap them around? You mean remove a cyan toner pump and re-assemble it for the magenta toner (and v.v.)?

No need to disassemble, they do fit but the pipe is at a different angle so you route it the shortest distance not using the clamps.

C.T.: you mean swap the pipes?
Won't there be contamination of cyan toner in magenta (or v.v.)?

Other than the angle of one of the connecting "pipes" all 4 pumps are identical. As for cross color contamination, there is very little toner actually remaining in a pump. Definitely not enough to make a visible change of the print color.

Slim, ok if you say so...
Everyday is just another day to learn new stuff, isn't it...

Done this a hundred times. Just slide the metal plate back on the pump and vacuum it out, it takes 10 seconds. Now you have a pump ready to go. Be sure and vacuum/replace the supply hose.

the mpc3002 pumps is the same as mpc2800/mpc3300/mpc3501 pumps and yes they all go bad.......
WHEN I GET THIS it is 90% always a bad pump.
I go into service mode and ck VT reading if it around 3.5 to 5.0 it is undertoned.
I will try a forced toner feed and see if reading changes if not swap out new or used pump..
If it is K i will use a color one but 1st run forced toner on that color twice and then vacunm it out n swap........
I only will swap from a machine in the field if i dont have a spare on hand...
It is funny you wont see a add toner call for a while and then get 3 or 4 in the same month
