The CD-ROM automatically ejects the bounce

The optical drive always bounces out of itself and bounces in automatically every other minute. have been so repeated. Explanation of the

CD-ROM automatic eject:

Normally, when the eject button is pressed in the optical drive Control Panel, the optical drive will automatically receive an electrical signal from the door, thus driving the tray to automatically "spit out"; Once the tray popup position is in place, The optical drive motor should also automatically receive the feedback signal to the tray position in place to ensure that the tray ejects the optical drive motor immediately cut off the power supply. When you put the disc in the CD drive tray and you need to close the door again, as long as the optical drive warehouse façade panel in the pop-up button, the CD-ROM control circuit will detect the feedback signal has changed, while the control circuit will be issued to the optical drive motor reversal signal, which led to automatic tray shutdown, wait until the tray close position in place, The optical drive motor will also get the tray signal in place to ensure that the motor stops turning immediately.

According to the door closed and pop-up working principle, the CD-ROM door automatically "spit out" fault and the computer operating system has no direct relationship, this fault is mostly the CD drive tray access control circuit work instability caused, but also may be the optical drive input power instability caused, Even both of these factors are possible. To verify that the input power of the optical drive is stable, you can remove the failed optical drive from the computer, and then install it to the normal computer for testing, after testing if you find that the CD drive in the computer will still occur in the door automatically "spit" fault, which proves that the CD-ROM tray in and out of the control circuit must have been a problem.

The solution to the automatic eject of the optical drive:

You can check the optical drive working circuit carefully, and when you look at the location of the optical drive panel, you can take it off and look at the back, and see that there is half an arc-shaped control device on which the switch happens to be in the groove below the optical drive tray. When the CD-ROM tray is ejected, the Groove will drive the switch on the half arc device to the side, control the optical drive motor to stop rotating; when the optical drive tray is closed, the Groove will drive the switch on the half arc device to the other side, control the optical drive motor to stop turning. After the author carefully to the optical drive control circuit repeatedly observed, the optical drive door is automatically "spit out" is due to the CD-ROM tray closed always in a false position (that is, not completely closed state), at this time the ARC device on the active switch is always unable to be in the pop-up or closed sites. After careful study of the author found that the half arc device on the active switch is not in place, is due to the drive motor belt relaxation phenomenon, the replacement of the optical drive automatically eject phenomenon disappeared.

CD-ROM automatic eject there is a software program failure:

can try to use the latest version of anti-virus software killing, if also did not find a virus, if suspected Trojan horse or spoof program in mischief. On "Run" msconfig , see "Start" "option, if you find a" Maxsder "startup item, the location" C:windowsmaxsder.exe ", then turn off its boot, the CD-ROM automatically eject the failure will disappear.

Considerations for daily use of optical drives:

When troubleshooting the optical drive, you can first use the replacement method to troubleshoot the optical drive hardware, or the host power source, if there is a problem with the optical drive hardware, it is best to send it to a professional repair shop or professional maintenance personnel repair , and do not arbitrarily remove the optical drive shell to repair themselves, after all, optical drive repair needs to have a strong professional knowledge as the basis, if the host power source, it is only to replace a host power supply.

① You turn off the optical drive too hard, causing the shutdown and then being ejected by your strength. It should be gently pushed. The

② optical drive mechanical failure, which is a hardware problem, is not related to viruses or software. If you are not very proficient in hardware, you can send the host to the local Computer maintenance agency for maintenance.
