Elura 50 record direct to SD card

SOURCE: Remove The Casette Message

I was having the same problem with my canon elura 70.  I called Canon tech support and they told me that there are three possibilities.  1) The camera is made to not accept tapes when the tape heads and path are dirty.  2) There is condensation in the camera.  3) There is an internal problem that would require you to send it in for service.
The first is a $15-$20 fix.  Go out and buy a cleaner that will clean, not just the tape heads, but the entire path.  In other words one that is not just a brush that moves back and forth, but one that winds on to both spools and gets pulled over the entire path.  Unplug your camera, take the battery off, take out the watch battery and the SD card and let the camera sit for about 20 minutes before cleaning.  Put all that stuff back in--PLUG IN the camera to the wall charger, then clean the tape path.8 out of 10 times this will solve the problem.
2) If there is a moisture droplet on the screen, this indicates condensation.  Unplug your camera and let it sit in a controlled temperature room for about 2 hours.  Do NOT use a hair dryer unless it has a no heat setting.  The heat can fry other components.  
3) If it isn't one of the other two...it will most likely need service.
Hope that helps. Don

I used my hairdryer to blow dust out of the cassette compartment. It worked for me.

I only got the problem when the tape was bad. Usually the ribbon got folded, or was very wrinkly looking. Eventually I found out the drive was bad, and had to have it replaced.
