Recenlty cleaned both ROS units because of missing stripes in the prints. After reaasembly CYK print fine but there is nothing printing from Magenta. Switched drums, also reseated the ribbon cables leading to the YM ROS. Still no magenta.

Docucolor 240 not imaging magenta

May be ROS, may be magenta developer assy.
Check again.
Currently back inside the ROS and I'm wondering if I put one of the mirrors in wrong. Checking in reference to the CY ROS now to verify mirrors match. I know if one is turned 90 degrees out it won't print.
Wrong mirror install !!! Mirror under magenta glass with spring.

Sorry. But clearly, you've buggered the ROS.
The ROS must be fixed.
Make it so.

Next time, you'll clean the ROS glass without popping the bonnet, eh?

Ha Ha very funny Ianizer but I had alreay done it that way to no avail. It was necessary to open the tops and clean internally as the toner fog had made its way to the mirrors inside. After further inspection of the mirrors within eac ROS I concluded all were installed properly yet still no Magenta. Any further advice would be appreciated.
I am ready to engage captain.
why dont you check if the magenta developer and drum are turning
Yes, but all indications are that everything was hunky-dory till the ROS was removed... Plan B- Prepare to swap ROS... Engage... -I
Oh wow, you remove the mirrors and lenses to clean them? I've had to clean my ROSes (ROSi?) more often than I would like to think about, but I never remove the mirrors or lenses out of the ROS housing. Seems very very fragile. I just take the top cover off and use a Q-tip which I wrap in a moist eyeglass lens cleaning cloth to wipe along all the various mirrors and lenses. It has worked every single time, first time with no lint and no streaking.
On a side -- but related -- note: The big box suction/ozone filter on the side of the machine... Is that the "main" filter for preventing ROS contamination or is there some other trick to eliminating (or at least slowing down) the contamination?
Re: Docucolor 240 not imaging magenta
I thought removing the lensi from the ROSi a bit odd too, but just kind of went with it... The suction filter does collect a lot of toner... The best solution I've found for ROS contamination, really, is just fastidious service... A key being to replace developer chemical at a reasonbly frequent interval... The 1M recommended developer cycle is a bit unrealistic, at least in my environments. -I
