Every two to three days it goes very light (washed out). If you tone it up it comes back. The developer and drum have been changed calibrated and processed. Machine only has 250k on it. Ideas appreciated.

Re: MP 6002 Keeps going light
if you repalce the developer in any other way then the serv.man. prescribes, this trouble might occur.

Re: MP 6002 Keeps going light
Light prints(and overtoning and dumping) on the 6002 (and 7502,9002) is unfortunately a known common issue. Ricoh released firmware to help with this issue. Also, see the attached bulletin.TSB Light Images_Toner Dusting_Over Toning.pdfLast edited by blazebusiness; 07-05-2018, 04:14 PM.sigpicAnything can be made to work if you fiddle with it long enough- San Diego Copier Repair.comComment

Re: MP 6002 Keeps going light
The first things I used to do when I had a machine that kept getting light in a short time is to clean all toner hazing from the PCU frame, properly clean the ID sensor, replace the cleaning brush and initialize ID sensor SP3001-002.Comment

Re: MP 6002 Keeps going light
Does it display low toner messages as well?
I had an MP5002 this week that displayed low toner messages after a toner change.
I reset SP2-976-001 to "0" to reset the toner bottle 'on time' counter and the bottle icon displayed full again but the fault returned a day or two later.
I replaced the toner supply unit because I noticed that the density was light (It had a new pcdu the previous week) and it's fine now.
Machine has 1.5mil on the clock and a new machine has been ordered.

Re: MP 6002 Keeps going light
All of the above as well as check toner delivery clutch and are they using genuine Ricoh toner?At least 50% of IT is a solution looking for a problem.Comment

Re: MP 6002 Keeps going light
do not waste time, immediately clean the laser polygon and all the various lenses and mirrors under the metal door of the optics ... (guaranteed 100%), I have become stupid for months on similar models to change developers, drums, sensors id, etc, etc"loneliness is an invention of the white man, when we are alone we talk to everything around us, we are never alone" (Ojibwa)Comment

Re: MP 6002 Keeps going light
If I remember correctly, I thought there was a technical bulliten regarding this problem where the developer unit needed to be replaced. I had an MP6502 go light on me after 85k total pages, replaced developer and it went light again after another 50k or so and I ended up replacing the unit and drum and so far its done well ever since.Comment
