Mini tape holder keeps opening and it displays error beeps... Has been used at beach on various occassions... Any help would be appreciated.. Is there anyway we could clean the inside mechanisms?

moisture in the cassette holder. Take out the cassette, leave the holder door open for a couple of hours in a dry, warm location, and it should work again.

I tried every method I could find from people posting on the web, but the method that worked for me is this.

1. Eject the tape and close the tape holder.
2. Turn the camera off and remove the battery.
3. Put the battery back in. Leave the camera off.
4. Open the tape holder.
5. Slide the tape in, but as you press the holder in to accept the tape, keep your finger pressing in on the holder, being careful not to slow the tape holder from moving downward.
6. Turn the camera on.
7. If it doesn't work the first time, press more firmly to help the tape holder accept the tape.

That's it. This method seems to work for me and lets me use the camera for a long while. If the camera is sitting unused for more than a few hours, I have to do it again. And each time I insert a tape, I make sure that I keep pressing as the tape holder lowers the tape.

the capstan motor of your camera is stuck up....check the capstan motor is there is some debris insert at the sensor...if nothing you find check also the bushing at the upper part of the motor....

This is a common failure in this model and unfortunately will not be resolved without a qualified servicer. The error code indicates a message for lack of reel motion. Most often it is an electronic connection problem and not an actual reel problem. Good luck, magic seadog

need manuel for cannon camcorder zr45mc

check the capstan motor if it is stuck up... find if there some debris inserted at the sensor...if nothing you find check also the bushing in the upper part of the motor

( c : cassette : 30 capstan fg ) ; your capstan motor is stalling - try ( other brand ) new tapes and gently ! swaying camera from side while loading - if loads , your tape mechanism is dirty or is going out of alignment ; - - if the camera will not unload tape ? the capstan motor may be failing ( connector is loose , corroded ) or - it is jammed and it needs . . . disassembly . . . to complete checking .

These type of problems usually result from damage to the tape transport mechanism, Unfortunately they are impossible to fully diagnose without a physical examination of the mechanism.
There is not a magic tweak for this i'm afraid.
Wish i could be more help

not geting in holder tht mean u must open ur casset holder and put in polethin bag for a hour and it will accept tape

I have the zr850 which I have used less than a dozen times, and it does the same thing as you describe. Was told by canon tech people to try a maxell brand tape and a head cleaner tape. Have not tried their sugestion yet. camera is 3 months old.
