cd eject difficulty; how to clean roller with pics

[stone36]

After some insight from Matt (thanks) I pulled apart my SC-816 to see if I could clean the roller that ejects the CD, my symtom was that while the CD would always eject, it would ejects slowly or "stutter" so here's what I did:

Start by removing the 4 screws on top market with the white arrows, then pull the top off, if you need some leverage pry against the black arrow.


Then remove the next 4 screws marked with the arrows to release the cd mehanism. A magnetic head screwdriver is GREAT in this step.


You will have about 6 inches of play from the cable that connects to the CD player. Below is the best picture I could get of the roller, though it will become easily apparent when you do it what you are looking at.


Get some rubbing alcohol and som q-tips, I just poured a bit in the cap from the bottle. The cog that has the arrow to it is the easiest one to turn because it will also turn the roller, and you will also push down on it to lower the roller track to get the q-tip in. push it down, insert the qtip and go back an forth, pull the q-tip out and turn the cog a little bit. repeat, repeat, repeat, etc....


I went around about three times and here is what the q-tips looked like after, both sides were this dirty.


Success!!! the CD now ejects quickly and perfectly each time, good luck.

Interesting and unusual. Should you use a magnetic screwdriver with electronics? I don't know nor care because I do it all the time.

Now in the Repair Database.

Outstanding repair, Stone. Thanks for posting this.

Just curious if this same procedure could be used to repair my CD player. I've got the stock CD / Tape player in a '99 S70 T5 (115K miles). The problem is that my CD player will never play a CD, it just spits it out automatically. I've read in this forum that my head unit is stuck in "reject mode" and I cannot find that post to save my life. Is there any way to reverse the reject mode setting? I've got the radio code, so I don't mind trying stuff.

Any help is appreciated.

If it's injecting and ejecting the cd, it's not the rollers. Try a CD cleaner disc. They are $5-10, available at drugstores etc.

Anyone have any more info on that "CD Reject Mode?" I am having the same difficulty on my S90. I did the microswitch thing and wiped off the laser with a Q tip, but still am having the issue. If the disc is already in the player, sometimes it flashes code "EE" and then I have to eject. However, most of the time, it takes the disc in and spins it up for about 5 seconds then spits it out. I even tried resetting it overnight to no avail.

A friend of mine will sell me one for a good price, but I don't want to buy unnecessarily if I don't have to. Thanks for any help you can provide. This appears to be a great site!

there is a mode switch which tells the motors what to do, pull,eject or play.Its normally triggered by movement on a gear.
Radio shack sells a switch cleaner and lube.You can try it on the micro switches.
I use to do repairs years ago and now gotten away from it. There is a company in N.J that repairs the factory radios,there was a posting on it,and there is a listing on ebay where a guy will fix any radio for $49.00

Not to be a pain, but 20 minutes of google searching as well as searching this site have come up with nothing. Does the shop have a website?
