Toner near end MPC 2000

[gestetner tech]

The MPC 2000 displays toner near end, it pupms toner down to the devbox,
This is what i have done so far.
New Toner pump
New toner end sensor
cleaned the small glaswindows where toner end sensor are looking.
Performed softreset
Nothing helps.

Dev unit?

Are you using OEM toner and is the copier in a high humidity environment. The toner supply tube can get clogged, it maybe necessary to vacuum it out while it is disconnceted from the pump and the supply ends.

back up NVRAM to SD card, then do an engine clear, sp mode 5-801. if it says non oem toner afterward, set sp 5051 to turn off the message.

hi Thanks i will try that.

[gestetner tech]

Did your proposal. but it did not solve the problem.
It just come tio my mind that the display icon show low toner as well. but when loking in to the devbox i can see that there are toner enough.
I even swaped devbox from another m/c.
So it looks like NVRAm are faulty???

Silly question. Have you tried changing the toner bottle ??

[slot]

silly queston if it has a paper bank make sure the lover door is closed at the rear corner as this can stop the toner bottle resettinghad this on an mpc4500 and a BW mp4000

clean nozzle , look out for small lumps, the toner is fed too fast and compresses and does not drop into toner pipe to pump.

hey did you check your TD SENSOR SOME TIME TD SENSOR IS DAMAGE?
or is machine display error massage?

Hey Guys
I dont want to be rud but if you read my postings you will se that i did all the sugestions you havetold me.
If i swaped devbox from another machine that means also TD sensor. if i swaped tonerpump that also include new lines, so no clogged toner there.
Since it fills the devbox with toner the pump are working.
It must be something else. It looks like NVRAM fault.

If, as you say, the dev hopper is filling up with toner your problem is probably the dev unit drive. You are getting toner forced into the entrance of the hopper by the toner pump, but if the dev unit is not turning the toner will not reach the TD sensor and will build up at the entrance hole, so it looks like the dev unit has toner but near end will display.

Remove the Transfer belt and PCU. Look at the dev unit drive gear inside the machine. check for damage to the gear. If the gear is ok it could be the dev drive clutch .

What color?Check the pipes

Toner near end is a calculation based on pixel count and toner pump on time. It is not directly related to the amount of toner actually in the cartridge. Dont worry about it until it reads Toner Empty. This is based on the Developer TD sensor.
