False add toner and washout on MP 5000

[rthonpm]

I've got a brand new MP 5000 that's been nothing but trouble. Within 750 pages the developer was shot. For whatever reason, no toner was getting to the developer, even the drum image was grey.
Did a dev change and the problem vanished, only to come back in a less severe form a couple of days later with a false add toner. Mylars in the hopper were fine, but I swapped the whole hopper anyway and re-ran the pro-con to darken the copies.
It's been two days and quiet so far, but has anyone else seen these kind of issues so early on?
You'd think the slightly new design would have helped a little bit!

We have not sold many but all ours seem to be working fine atm.

But basically it's still the same engine design as the older Aficio 2045 series and we
all know they can be hit and miss with add toner problems and dev roller filming.

Next time it happens, check the Vsg and Vsp to see how the machine is seeing the concentration.
If the Vsp is pretty high then pump the toner to see if that helps. If it does then the toner add mech is probably OK.
If the VSP/Vsg ratio is OK and the copy is washed then it may be the transfer. Altho changing the developer wont cure a transfer problem.
Also look at Vt, when the problem occurs.
Did you run 2801 and 3001 at setup and also after the recent developer change?
As Cipher says, they really didnt change much except the fuser and how the PCU is assembled. The rest is unfortunately sameold-sameold

You know I'm sure there's bad batches of toner around for both these machines and the MP3500/4500 (as they both use the same toner and dev)

When the MP4500s were all new and shiny I went to at least a dozen with not even 5k on the clock with washed out copies, poor solids and crapped up mag rollers. At that time the OEM toner seemed to be supplied in a weird bronzy/gold bottle, I ordered the customer some more that came in the more usual silvery/grey bottle, re-devved the machine and cleaned up the mag roller and things seemed to be pretty much ok.

There are TSB's on both units for the same issue. I was just fighting one today. I don't think it's gonna help, but I ordered a new mag roller assembly as it's been through 3 developer changes in under 140k. I've been de toning the new developer and vacuuming out the reclaim before running 2-801. Adjusting the developer bias voltage and checking the resistance from the flywheel to the chassis was part of the bulletin if I recall.

Try to removed all the developer powder and toner from the toner hopper and put a new one.go to sp mode 2963(machine installation).Maybe this one will help.I guest you didnt do this one.

you should take a look at this.
the toner hopper seems fail. Make sure you are using the right toner and the backgroung check the bulleting.

The correct toner was installed in the machine. I cannot say for certain whether the developer was correct as I did not do the initial set up. This series just seems to be really flaky so far. Now if I could only get all the false waste toner problems to stop as well!
I clean the connectors perfectly and without fail, one of my boxes says the waste toner is full about 50-100 pages later...
I only hope the MP 4050 will be a better machine.

You might want to try bending the contacts up on the door. I've had a few that weren't making good contact also.

Try to calibrate your developer with a new one.Regarding waste toner.Check the sp modes 29??(Toner Suction Collection Bottle Time) and 29??(Toner Suction Motor Operation time),put the value to zero and turn off the m/c.but off course check your sensor also.Maybe this help.

Ten years after...350/450,the same story!!

[FRIDGEMAGNET]

I would be inclined to switch the waste detection off - sp2-960 set to 0 untill they come up with a proper fix.
But you would need to check it every call - just like the 350/450 series.

toner and toner add prob

Being of the nad / adonis family of machines, it may be worth checking the toner bottle supply motor, good luck
