I replaced the mirror that's supposedly the problem, no change. Hotline suggests adjusting scanner position so that it's nice and straight from op to non-op. We'll see.

You have to check the factory settings again, SP 4685-002 for DF ,4686-002 for DF 4687-002 DF it should of course be as its written on the papper that you find in the cover. if we are talking copy from Df
Re. fuser oil, on the mirrors i have never seen that on newer copy m/c,
Some one asked me before about my time in the business, since Xerox 1040 so it`s around 25 years

All mirrors are used and you would not get this fenomena even if there are some dirt.. And Never Never Use any solvent on mirrors.Only dry cloth.
And problem was that i missed a line in factory settings when replacing NVram, the gray settings in DF mode was wrong....... "
Gestetner TEch Can you please give also tips to where you can find or read a service manual saying don't use alcohol(the best solvent) on the mirrors?You are asking for tips but you don't even say thank you to the people who gave you time. Instead you are saying you're 25 years in the industry. Years are not the barometer of a good technician. It is the humility and respect that matters. I have asked help here in this site but I never pretended to be the best. Please refer to the service manual preventive maintenance - just use the manual of DSM 615,etc. page 2-1.

Hi rsyarcia.
Well you can read the manual of for example MPC 2800 PM
Reflector C Optics cloth1st/2nd/3rd mirrors C Optics cloth
Its ok to use Alcohol on scanerglass,
But i learned By 3M and others that never use any solutions on mirrors becouse you will harm the silveroxid that mirrors are made of.
Some say that use compressed air, thats not a good solution becouse the drive gas in the bottles are danger to mirrors.
And by using a compresor you can get oil from it. so a Optis cloth is what should be used.
regarding saying thank you. well i appoligize.
I asked for tips , but found the problem myself, all the tips was not relevant to the problem.
Ok I red the service manual and it is very obvious that you disregarded the other mirrors in which we can use alcohol especially the exposure glass and ADF exposure glass. We are not only talking about the 1st/2nd/3rd mirrors it is the whole optics. And it is very clear that we can use solvents(e.g: alcohol). We are doing Ricoh machines and not 3M and others. Just base on the PM when you gonna use solvent. Anyway thank you for your post.

The only parts that you should not use alcohol are the mirrors as written in the manual. when i talke optics i mean the mirrors and the lens on CCD the expossure glas and scanner glass i dont refer to optics in that way, and its ok to use alchol on.
What i meant by 3M was that many yeares back we worked with OH projectors that had big Mirrors inside, and we was teached to never never toutch them. we also work with Ricoh. I v been Ricoh tech since 1997.
