ricoh 2045 toner end lock

[diegojavbau]

Hi everybody , I have a ricoh 2045 that is locked in the toner end condition.
The main problem is that the machine dont go into the "Adding toner" situation after the bottle change , neither after the open/close front door , the bottle motor dont turn on .
1- I dissconnect every front door switch to try if some is "sticky"
2- the motor works fine when I turn it on manually.
3- the copy have enought toner (just a little saturated maybe)
4- I made a clear memory , but after a couple of copies the out of toner signal reapears.

The problem is that the machine is loked as if dont "notice" the open/close door.

Any sugestions ?

PD:sorry for my english

If it is not even trying to add toner it probably is a door switch. I would just replace all six of them and try it.

Why not try to clean out the whole toner hopper unit .

I recently change the switchs of the right door , so I will try with the front door.

I already check it , but the machine is not even trying to add toner

Just to make sure your motor is working check it's operation in SP mode output check. If it does work, you may have a bad TD sensor. When the machine is trying to add toner and the bottle IS turning, you may have a bad toner supply unit.

I Already do it , the motor works fine.

I think that in the begining but why is the machine asking for toner and dont try to add it when I open close the front door ?

The machine is not trying at all

PD: I all my search , I cant find any sensor that check if the toner bottle is in place or removed , so ...

*What is the trigger that launch the toner recovery process and erase the out-of-toner signal ? Just the open-close of the front door?

*Is there any way to clear the out-of-toner signal from the SP mode as in the ols models like the 3213 ?

The manual says that the machine should start to add toner once a new bottle is placed. Abnormal readings of TD-sensor and ID-sensor should result in SC-codes. So if you're not having SC-codes you could rule these parts out, I think.

Maybe you could try a forced toner supply (SP2-207)

[mikadonovan]

Definately a wierd problem. I would do a developer change and then run TD sensor initial setting and see if that doesn't remedy the problem.

[Fearless V K]

What is the TD sensor reading?

[diegojavbau]

I try the TD sensor adjustent without results (but no new developer) , also use the forced toner supply , problem persist.

I will take note of the td reading and come back

Thx to all

I think you machine doesn't add toner because the TD sensor values are wrong and mislead the engine to take any action. Replace the dev unit and put a fresh bag of developer, but before reset all the values to their defaults.

I think the front door should be opened for x seconds for the machine to start toner recovery. I had this problem before, and then I just turn the power off and the machine will start toner end recovery when its turned on.

[diegojavbau]

I finally solved (till today)
1 - I clear the memory of the machine.
2 - turn off and on to take efect and clear the condition
3 - Make a TD sensor initial setting before any copy

Now , after an exit jam (C point) the misfeed indicator locks , the only way to clear is erasing the memory again.
I will try changing the sensor , but joined with the previous problem I start to think in a weird problem , like some kind of fail in the doors reset system

[Koosie]

Most likely the front door switches, because to clear a C jam, the front door needs to be open and closed, because the machine wants you to turn the fusing knob.

You ranthe motor in sp mode so the switches are ok, I agree with stephend td sensor theory. ( on a lighter note- you could always buy a manual, there's a wonderful site called manuals4skinyou where they sell them insted of trying to help you)
