Re: yellow covers
Usually when the plastic has yellowed it's because some form of chemical reaction has taken place. Usually due to exposure to sunlight for long periods of time, or from heat exposure from the machine fuser.
Neither of which you can clean off. You might be able to sand off the top layer of plastic if you are really determined though.
We have one MP3351 that has a lot of yellowed plastic around the OP panel, probably from the large amount of heat that particular unit belches out of the paper exit slot. -
Re: yellow covers
When the plastic changes color there is no way to clean it back to original color.
years ago there was a company that sold matching paint I used to use, I believe it was Keller Industrial Finishes but I haven't used them since back in the Mita days.
I'm thinking that's why some manufacturers are going with all black covers these days.Comment

Re: yellow covers
Like the other gentlemen have said, the change in color is the result of solvents leaving the plastic, leaving it brittle. Even aggressive sanding will expose only slightly less yellow plastic underneath.
You have three choices:
1) Leave them yellow.
2) Paint the covers.
3) Buy new covers.
I've seen it done all three ways.
1) If you leave them yellow, it isn't that aesthetically pleasing, though the refurbished machine is just as serviceable as it would be with new covers. It just looks like somebody's old machine.
2) Ikon used to powder-coat the covers, and they don't look bad, but keep in mind that most of the cleaners you use to clean the covers also will remove the paint, revealing yellow plastic beneath. So when you get toner smudges only use water based cleaners like glass cleaner.
3) This is the most expensive, and the best looking result. You just can't beat new covers for that shiny homogeneous appearance.
I suppose it depends on your customers opinions and your pricing structure.
Does your customer care if the covers are yellow?
Did you roll in enough money to pay for paint or new covers?
Maybe you can offer multiple options? $5K for the refurb with scrubbed covers, $6K for refurb with painted covers, $7 for refurb with new covers? Your economy minded customer can congratulate themselves on how much money they saved. =^..^=If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Re: yellow covers
Also, when parts become yellow like that there is going to be problems with their structural integrity. As such, the parts that turn that color are going to be petty fragile.
Just something I saw when I was working on the MPC2050 type machines.Comment

Re: yellow covers
We used to buy colour matched 2k automotive paint (colour + hardener) and would lightly sand the covers with light grit waterpaper (after having thoroughly washing the covers, and letting them dry.
Then blow off all the sanding dust with an aircompressor and then coat about 2 coats 2k.
It worked for the most part as it was much more hard wearing than aerosol spray paint.
Only thing is because hardener is involved make sure you spray with proper respiratory masks made for small particles, as inhaling hardner, over time with damage your lungs.
A litre went very far when compared to the cost of it.Press the GREEN button!!Comment
