Developer in the PCU gears

[xcopier]

Recently, i noticed that developer powder is making it to the gears of the PCU of our MP2000.

This creates rough, grinding noises and worn out some of the gears.

What could be causing it?

Thanks in advance for your inputs.

Age and wear and tear on parts. Best bet is to replace the lower dev unit or the mag roller gears will get eaten as well, eventually it won't work at all or will seize.

Generic Dev?
It's caused me issues like this in the past

This often happens because the developer unit was not replaced.....just the developer/starter. When we rebuild the pcu we replace the drum,developer, and starter to ensure reliable performance. Replacing all those parts is expensive though, so many customers just install the Type 1027 PCU and run the developer calibration. While that works and lasts quite a while, and is very affordable, those 1027 drum units don't last as long as they normally would because the dv unit gear drive is slightly different.

Normal wear and tear on bushing in the bushings the development unit. Truthfully it is only normal if you try to push the pm cycle or use third party developer. Depleted developer gets into the bushings which further wears them.

we rebuild units all the time. Replace seals and gears and you have to look at auger shafts it worn you have to replace lower unit. i have ran oem devlp and toner units and they last as long on the generic stuff. Other things is foam seals wear out so at some point you have to replace lower units or mag holder assy. i buy devlp powder from copylite and toner and seals and gears from china.

I only replace development units when this issue occurs.
Pouring developer in the development tank needs to be done without spilling, thus very carrefully.
Transport a mp2000 could case this issue too.

This was our normal practice as well. Seemed to work fine and almost 99.9% of the time eliminated the dev working in the gears problem.

But Ricoh has recently discontinued the Type 1027 PCU. We are out of stock and currently looking for an (gasp) aftermarket solution for our customers that just flat refuse to upgrade to a copier built in this decade.

Good luck everyone

I hope that’s not true

We scoop out about a tablespoon of developer, from day 1 on installation. It really works and the loss in yield is negligible. Copy quality issues annoy users less than a machine asking for toner when the bottle is full and sitting with a seized dev gears...especially if they already waited a day for the toner delivery just to have toner spilling everywhere and making a mess when they try to change the toner
