Re: Yellow plastics
Get the peroxide that is used in beauty salons to color hair (see attached) Amazon sells it. Brush it on plastic, cover with clear wrap and put in sun for 30 mins each yellow side. Will turn as white as a baby's ass!Comment

Re: Yellow plastics
.
Since longer, we use for the real cheddar cheese like discolored plastic a secret substance called:
PAINT
Sick of all the scrubbing, using peroxide, bleach etc., I took once a clean bright cover to our hardware store where they scanned the plastic with their equipment and got from them water based paint 99.5% exact the same color as the panels. The formula is stored in their system, so when I need it again it is very easy.
Sounds complicated, but is easier and taking much less time than the other above-mentioned methods. We apply two coats with foam rollers. No spray nor brushes, just coarse foam rollers to achieve a slightly rough surface like the original plastic.

Re: Yellow plastics
What about the machines stick on labels, model #, serial, etc. Do you buy them and replace?.

I remember back in the day when the machines were completely rebuilt by taking machine apart almost to the frame and while rebuilding sending the panels out to a place to get repainted. It was a big business back in the 80's / 90's. But most of the panels had badges on the front cover that could be removed then put back on after painted. Also several companies use to sell copier paint "Ricoh beige", etcComment

Re: Yellow plastics
On the "white" covers there are luckily mostly no labels and when, I re-make them with self-adhesive clear copier foil.
Ninety percent of our machines are rentals and must be perfect, are perfect and must look perfect too. Most of our customers are lawyers, accountants or medical doctors with modern fancy offices. For me, it's a horror to come there with machines with yellowed covers. No Way!
More than once when we came in with our machine - neatly wrapped with foil and packing material - customers asked, if that is a new machine....?
For many of our colleagues here this would probably be too much work, but for my colleagues and me, it's easier to repaint a cover than all that stupid scrubbing with chemicals and lost time and anyway less perfect results.

Re: Yellow plastics
My only caution is that IF you're going to paint the covers, remember that they're painted. Chemical cleaners like Zep Fast505, and Orange-Sol, which do a very nice job of cleaning plastic covers ALSO do a perfect job of removing paint.
During my IKON days we got some Canon machines refurbed at a factory location in Mexico. The covers were all powder coated and looked nice ... at first. Then they started to get fingerprints (no surprise) so I'd scrub them off with Orange-Sol. The first few times, no problem. Then you'd see that the paint was getting transparent, or you'd get bare spots.
Glass cleaner or water does not do as good a job of cleaning, but it does preserve the paint.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 plastics
Cat, this water based acrylic paint I'm using since years and have not seen yet any negative experiences. It also seems not solvent or cleaning materials sensitive at all when it is cured.

Re: Yellow plastics
That's a good name for them. They disassembled the machines down to the frames, and cleaned EVERYTHING!
But they didn't change a single part. Not even to make the machine operable. Typically, it was the salesman's job to run the machine in the office for a week or so to identify the typical failures for that model, and change out the parts that were needed.

Re: Yellow plastics
Almost sounds like what the unscrupulous dealers that do very little to a off lease or trade in machine before selling "Spray & Pray"Comment

Re: Yellow plastics
I fully understand about how a machine looks if yellowed. I've actually bought higher meter off lease machines because they had white covers.
What is weird and could never figured out is why some of the paper drawers turn yellow but the machine could be nice and white. My guess is the drawers are made out of different plastic or were in a place the sun just hit that part of copier.
Forget about back in the day when workers were allowed to smoke in offices, talk about yellowed covers!Comment

Re: Yellow plastics
I wondered too and came to conclusion yellowed faster covers are made from recycled plastics. Which is good for environment but bad to see. However as a tech I would prefer parts inside machine to be in good shape than outfit but fully understand what Hans talk.A tree is known by its fruit, a man by his deeds. A good deed is never lost, he who sows courtesy, reaps friendship, and he who plants kindness gathers love.

Re: Yellow plastics
The problem is, that almost all customers -being non-technical - judge a machine according to its appearance alone. Your machine can have all critical and essential parts brand new, but when it looks from outside, because of its appearance and color, like a used up oldie, it's hard to convince them about its qualities.
