Replacing Polygon mirror/motor in D125

[Rjeffers]

I'm a printer, mostly offset, currently working in mail processing. I have been asked to install a new polygon mirror/motor in 1 of our Xerox D-125 printers. I'm no technician, or printer specialist. I have it in quite a state of disassembly, and still have not located the ROS unit. Most searches show it at the exit end of most machines, except there are very few videos/tutorials for Xerox. Can someone please point me in a direction? I'm getting tired of staring at it, and really ready to return to processing mail! Any help would be appreciated, and thanks in advance for any replies!

why would you want to replace that motor?
you have to order the whole ROS (lazer)

+1 and this should NOT be attempted by an end user / newbie without service manual .. many adjustments needed after install

Honestly, my boss handed it to me, and told me to research it online and put it on. Not much info found online, and was looking to save myself a lot of time removing things that didn't need removing. I do understand you guys are technicians, and are paid for your knowledge and expertise. I meant no disrespect to anyone. I do appreciate your input.

the only place you might be able to score a laser unit ( since you are not a tech ) is here printer parts and supplies and rentals item inc

but they are rather pricey talk to Whitt

The ROS is in the top of the machine, just below the copy bed. It is never in the exit area, on any machine, or any brand I've ever seen or even heard of.

Not sure how much you have disassembled, but you get to the ROS from the top, as I said, and you don't need to open up or remove anything from the sides or back, except some of the plastic covers. The whole copy bed flips up on hidden hinges out of the way like the hood of a car, to give you access. But make sure you put a spare screwdriver in the main hinge on the back of the document feeder or when you flip it up it will fly open violently.

I don't mean this as harsh criticism or anything, but changing the polygon motor is almost never done, even by experienced techs, as others have said. It is an extremely precise part, and not intended to be removed from a ROS and replaced. If you don't really even know what or where the whole ROS unit even is, I would consider changing the polygon motor ON the ROS assembly a... poor choice of direction. Even replacing the ROS itself on this model is not a "beginner level" repair.

You may want to rethink about taking the ROS out, if done wrong you could injure yourself at worse loose a finger if the top part falls out it could crush or cut your fingers or hands off, inside the printer there is actually a metal bar that screws down to help you lift the top part up that's how heavy it is so save yourself a little trouble get a tech out there. The first time I took one out it took me almost 2 hours to get to it that is with a service manual. With that said, good luck.
