Difference between MP6000 and MP8000

[charrex1]

Does anyone know what the differences are between the MP6000, MP7000 and MP8000? I know there is the speed difference. 60ppm, 70ppm and 80ppm. But what makes that difference? I've looked through the service mode in the service manual, but I can find no settings that make the change. I've checked the parts catalog, but all of the boards are identical. I have a MP6000 next to a MP8000 with the covers off and I looked at all the boards and can find no difference in jumpers or dip switches. I even tried swapping the NV-RAM between the two machines and it changed the name listed on the config page, but it made no difference in the copy speed. How do these machines know what they are? Same thing for the Pro 906 and Pro 1356.

Hello Charrex,

I believe the programming and firmware installed on production is what determines whether or not it is a 60ppm, 70ppm or 80ppm.
There's a completely different set of timing and registration settings (I guess)

If you're attempting to increase the speed of a machine I think you may hit a wall without specialist help.

I personally have not noticed any obvious physical differences and I have borrowed parts from a spare 5500 to fit to a 6000 several times.


I would recommend looking at the non-default print out from both machines (SP-5990-???) in fact I will do so myself when I have a chance.

NV-Ram won't affect much except the machines counter and serial number / name 'Identity' the NV-Ram doesn't contain any settings as far as I am aware.


Sorry about double post.

Richariri,

Thanks for the quick response.

I did check the firmware and it was the same between machines. I also printed out the service reports (5990) and couldn't find any difference. I also tried swapping the controller board(with the NV-RAM) and BCU board, but it made no difference.

I have worked on Ricoh copiers for almost 30 years and always thought the difference was in the main boards, but these are the same. I can't find where the difference is.

Re: Difference between MP6000 and MP8000

Most of the times, the times both the machines run at the same speed. The only difference is the interval between two paper feeds. In the faster machines the interval is shorter. There is a difference between the two machines, but you'll won't find it. Could be different wiring, or something, etc...

And is pretty obvious you won't find this information in the SP-modes....

No problem Charrex, sorry I couldn't help

One thing that have seen is that a portion of the serial number identifies the model.
