Ricoh mp 9003 toner hopper leaking toner

[n25an]

How many prints has this copier done? After a mil I am quite happy to replace the entire toner delivery assembly as the foam seals either side of the toner delivery roller wear, toner leaks through and you start to get over toning problems.
Also keep a close eye on the developer unit and the moment it starts to leak developer past the seals on the mixing shafts its time to replace it.
The quickest way to kill a Martini is to ignore dev leaks as the dev gets into the paper feed and makes all the nylon gears wear rapidly.

And I also think that the Martini range is one of the best that Ricoh ever produced.

the machines have a million plus prints
whats the part number for the toner delivery roller???
are there any seals that can be replaced on the development unit to extend life or its just kaput???
thanks for the point on the nylon gears... will keep that in mind...

I have encountered machines where someone forgot to open the toner throttle after putting the development unit back in. It causes toner to be forced out around the neck of the bottle.

If you get persistent under toning, check the nylon gear on the bottle motor. It will shrink with age and start jumping teeth.

interesting...
I have replaced a sensor on the bottom of the developer unit(part number AW230046..) when I get undertoning... or light prints... I believe thats the same thing... correct me if I am wrong... I can force toner load but that only lasts a short time...
I have noticed a setting on these machines in the service mode to ignore this sensor... could not get it to work.. I believe its the td sensor... part number AW230046...
anyway back to my question...
is there a way to make the machine ignore this sensor and load toner via some other adjustment... ??? I saw a setting to load toner according to print density but that does not seem to do anything...

thanks for the catch with the bottle motor... I think you are talking about the motor thats part of the toner hopper... underneath... let me know if I am wrong...

Replace
D1313161
A2293266
A2293263
A2933234
A293 3227

Good Luck!

ok...
D1313161 -- sits untop of the developer unit
A2293266 -- upper shutter shield on toner hopper
A2293263 -- lower shutter shield on toner hopper
A2933234 -- shield plate that sits behind spring loaded part of toner hopper
A293 3227 -- toner slider... I guess when it sticks it creates an openning for toner to get through...

ok... sounds like you are covering all the bases...
how often have you replaced these parts and how long does the fix last...???

thats a lot to think about... thanks all
god bless you everyone...

With the Martini models, if force toning brings the image back, you might have a dirty ID sensor. These models are known for dropping toner from the cleaning station. If cleaning corrects the problem but it comes back in a week or so, replace the cleaning brush and cleaning entrance seal.

I always carry all the set, and see what is needed to replace. -3227 and -3234 are the most wear out, -3266 also is often disintegrated, -3161: check the seal and -3263 is almost never replaced.

All this for the toner spilling issue. If there is developer leaking there are other parts involved.
Good luck!
