What's going on with the automatic eject of the optical drive?

Problem Description: Netizens just bought a new computer, found that the optical drive is always bouncing out of their own and automatically bounce in. have been so repeatedly, in the end what is the fault? Consult our computer engineer!

CD-ROM automatic eject explanation:

Under normal circumstances, when the optical drive Control Panel in the Eject button, the CD-ROM motor will automatically receive the door to eject electrical signals, thereby driving the tray automatically "spit out"; Once the tray pop-up position in place, the optical drive motor should also automatically accept the tray position in place feedback signal, To ensure that the tray eject after 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 working principle of closing and ejecting of the storehouse door, optical drive door automatic "spit" fault and the computer operating system does not have a direct relationship, this fault is mostly the CD drive tray in and out of control circuit work instability caused, but also may be the optical drive input power instability caused, or even the above two 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.

CD-ROM automatic eject solution:

We can carefully check the optical drive working circuit; To see if there is a printing plate at the position of the optical drive panel, you can take it down and look at the back, and look at the half curved control device, the switch on the device is just in the groove below the CD-ROM; when the CD-ROM tray pops out, 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 also 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. In the "Run" Msconfig, see the "Start" option, if you find a "Maxsder" startup, Location "C:windowsmaxsder.exe", then turn off its boot, the CD-ROM automatically eject the failure will disappear.

Daily use of optical drive considerations:

When troubleshooting the optical drive, you can first use the replacement method to troubleshoot the optical drive hardware, or the host power source, if the CD-ROM hardware problems, 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 self repair, After all, the CD-ROM 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 shut down the optical drive too hard, resulting in the closure of your spare strength after the eject. It should be gently pushed.

② Optical drive mechanical failure, is a hardware problem, and virus, software independent. If you are not very proficient in hardware, you can send the host to the local Computer maintenance agency for maintenance.
