[Dead] Lanier MP C2003 Magenta Developer Hsg Froze then Toner Pump failed 2 weeks later

[Doug James]

Hello, I went to a call a few weeks ago and found the Magenta housing main drive gear was froze and replaced the entire magenta developer housing with a new OEM and the machine was working fine. A couple of weeks later I get a call that the magenta toner cartridge was showing empty when it was full. I go to investigate and find the magenta toner pump was not delivering toner to the developer housing. This customer is using OEM toner. Is there something I am missing here. I am planning on installing a toner pump but is this a normal problem with this model ? Thanks so much for any responses !!!

OEM or Genuine Ricoh. There is a difference. OEM merely means the same basic recipe as far as components. It does not mean the same quality control and definitely does not mean the same particle size. The OEM toner is most likely what caused the development unit and pump to fail.

+1 most problems noted here are due to crap toner and drums. bite the bullet buy Genuine OEM toner.

I believe Genuine Ricoh (It had the Ricoh Logo on it.)
I am actually not sure....

There is no toner pump on this model, just a hopper & gravity.

What happens is when the dev unit gear fails toner backs up into the hopper & breaks the auger.

Basically you'll need to replace the magenta toner hopper.

This. Have seen it many times. Always when the dev unit takes a crap replace the toner hopper and vacuum out the chute. All the 03 color and 04 same design.

But does it say Genuine Ricoh on the box?

We only use genuine toner & this issue happens all the time.

Common replace with new oem dev assy and toner hopper is damaged also there's a little toner assy going on back frame goes between hopper and dev assy remove and clean toner blocks up

hi, it happened to me on some 2003, in my case it was the development group blocked / hard to turn and the toner compacted in the hopper breaking the plastic worm, I think it was done on purpose, otherwise the toner he would have overflowed the machine internally by dint of loads

Hello everyone, I know this is an old post. I have 3 MPC2003 maintained since new in I think 2014. I am a new member and I fleshed out my BIO incase stranger danger flares up with anyone. I would appreciate your direct knowledge on this matter. My observation of your indirect knowledge of many issues over the years has been critical to my success (and a service manual).

Code being thrown is SC360-02 at current.
Prior and briefly it was 360-02.

The TD sensor which as I can understand it is somewhere in the PCDU isn't serviceable and is symptomatic of some issue i can't seem to understand. The headline SC is for Cyan and the gravity well leading to the Archimedes screw(auger) was overflowing when pulled out. K was not at all like that and I took it out to compare(despite the brief SC code on line 2).

he auger works as far as I can tell. I.e. it is attached to the gear on one side at least but i didn't revolve it. This was all preceded by a sound from the unit that could only be described as plastic gears deadheading against something immovable. Nothing is stripped but it never made that sound before. I think the guys dropped it over a 3 inch threshold and it jarred something.

My questions

1.)The roller is mylar I think and the developer separates from it by the front and rear covers. It is completely inundated with toner and my research doesn't tell me what your experience, if you are all so kind, could do more certainly. How much can that roller handle being cleaned or should i replace it?
2.) I am only occasioning to replace the developer to repair whatever malady the TD sensor out of range (4.6v above an Initial of 3.6v) is symptomatic of. Maybe the density of the the toner in the auger is sensed through some feedback on the driver motor of the auger? I would like to know, but I only wish to understand if my repair path is verging on accurate or if I am lost.

Thank you all
Elbert

If you pulled out the cyan and it was backed up to the top of the inlet port then most likely the dev is beyond repair. stripped gears or seized bushings most likely. replace the dev unit but also check your toner hopper as the coil is most likely damaged also the vertical chute from the hopper to the dev unit may be plugged
