How to force open a jammed DVD drive?

I've been attempting to repair my iMac G4's DVD drive for quite some time now. I have been successful in opening the machine and accessing the hard drive, but I have never actually removed it completely from the computer as I can't seem to find a proper ejection hole that would allow me to force the tray open manually. I found what appeared to be a button, which I'm guessing is where the button from the original bezel would have been placed, but thanks to Apple's design, it's untouchable when fully assembled.

I have tried all software methods as far as I know: nothing is inside the tray, so I can't drag it to the trash; holding the mouse button down during startup fails; reseting the PRAM or going into Open Firmware solve nothing... etc.

When I hit the eject key, you can clearly hear the DVD drive trying to open. If I pull down the outer tray door, you can see the front of the drive and that a small white gear inside turns ever so slightly before stopping completely. It refuses to budge. I am thinking that a motor or rubber band may have broken off somewhere, but I can't say for sure.

The computer specs: 17-inch 1Ghz iMac G4, 1.25GB of RAM, 80GB HD, runs the latest version of Leopard. I like working with the machine alongside my MBP. Help appreciated.

On an iMac G4, can't you pull open the outer optical drive door? If so, look for a paper-clip hole on the front of the actual drive mechanism; that should be the emergency eject hole. You should be able to insert something into that hole to depress the hidden button.

If that does not work, it must be some mechanical failure (as you mentioned yourself).

This take apart guide offers some advice for replacing the drive.

It should be a standard tray-loading optical drive, unlike earlier and later iMacs. It mentions a consideration for the length of the drive. The drives sold by OWC will probably work.

I have not been able to find any hole on the front of the DVD drive. That's why I proceeded to inspect the inside of the computer. The few times I have opened the machine, I have not found anything useful. I have considered taking the whole thing out, but I'm a bit hesitant to do so.

I have referred to that take apart guide. The images in the guide seem to be of the older G4 units, but the internal component arrangements are largely the same. I would prefer to be able to save this drive if possible, but if it proves I cannot, I will consider looking into a new one. Unfortunately, I have yet to find any sort of video or picture guide that has shown me where the hole on the drive could be, or how I could manually open the thing.

iMac G4 Take-apart for Drive and RAM upgrades:
http://www.xlr8yourmac.com/systems/imacg4/imacg4takeapart.html

{If replacing a defective drive, while in there, consider other items
that may be in need of attention; de-dusting the interior, upgrade the
hard-to-access RAM slot (in 1.25GHz iMac, can use 2GB total RAM)
and if the hard disk drive is getting old/tired, or too small, there it is.
Also, the clock battery. New thermal paste and a lot of details, too.}

Additional searches of iMac G4 take apart may yield more clues.

There used to be some fairly handy official documents available,
if you were an authorized service tech. Others were unauthorized
ones hosted online and those were pulled eventually. A place such
as iFixit has portable computer and later iMac take apart info; but
not sure of similar info online for the entire iMac G4 machine. For
my own information, used to troubleshoot my own iMac while it
was requiring repair and the authorized shop was unable to find a
single thing wrong with it, I have an original service manual in pdf.
And I troubleshooted the computer under AppleCare and the shop
was told to just fix it, after 3000 miles of travel to/from their shop
and six months of not being able to use the computer. The company
who messed up is no longer in business here. It soured me on mac.

Good luck & happy computing! 🙂

Hey MacUser,
If I pull down the outer tray door, you can see the front of the drive and that a small white gear inside turns ever so slightly before stopping completely. It refuses to budge.

It can happen that the disk gets displaces and can jam the door. Sometimes shaking it helps.

In most of these I've seen, they're direct driven usually via a rack. If something gets in there it can jam. I've worked on these using something like a trimmed chopstick to move the gear (or a toothpick). It takes a lot of rotations but I've opened them that way.

Sorry for replying so late. Been busy.

I've been unsuccessful in turning the gear at all. Applying more pressure yields no result. I've tried paperclips and a small screwdriver, etc. It just wouldn't budge. There's no disk in it, so I'm a bit stumped. I'm guessing I'll have to order a new drive one of these days.

As to the guide posted above, I've referred to it several times. Taking it apart isn't the problem, just actually taking the drive out. I'll have to look at it more over the holidays.

Some of those optical drives appear to have a belt-drive and pulleys, so
moving a gear mechanism won't do anything; belts can slip and not let
a drive tray or slot mechanism eject an optical disc from the computer.

Once the actual drive is out of the computer it may be possible to dis-
assemble the optical drive to (hopefully) extract the disc held within.

Good luck & happy computing! 🙂

I suspected that. If I find time to take it apart again, I'd hope to pop the whole thing out and see what I can do. I'm hoping I might be able to swap one of the drives I have lying around with, but I can tell if it'll fit in the carrier or not. Again, been so busy to get back to it. I do appreciate everyone's help though. Will report back once I set a weekend aside for maintenance. Thanks.

Have you gotten the chance to repair your optical drive?

You may have already tried this but in case you haven't...Boot or restart and immediately press and hold the OPTION key. When the Startup Manager appears on the screen, you may press the EJECT key on your keyboard or click on the cyclical arrow symbol on the screen; either way it might take the drive several seconds to respond.

Solution!!!

The Imac g4 has issues ejecting the dvd drive and Cd drives.

This is very common i just ran into this myself.

Solution the dvd drive will only eject if there is a os on the imac it has to do with the imac's firmware update when installing tiger..

not the end of the road...

i found that if you connect a external cd-rom/dvd-rom drive to the imac via usb or firewire you can boot the mac os x tiger installation off of that and once it is installed the mac will eject the cd drive and you can disconnect the external.
