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 just received the following information from Canon. Similar to Donjr's.
"The Remove Cassette issue is currently a big issue with Canon camcorders, however, it is not due to the camcorder. Canon USA has found that the cause is when customers use multiple brands of DV cassettes. Each different brand uses a different lubricant and when these lubricants are mixed they congeal and hinder the camcorder heads from moving. This can cause the Remove Cassette error. When this message is received Canon recommends using a dry cleaning cassette to clean the lubricant off of the camcorder heads. You can obtain a dry head cleaner at any local store that carries electronics equipment. If this does not resolve the issue, then the camcorder may need a Tape Path Alignment, or the posts may be loose. This would require servicing to resolve the issue."

I have purchased a cleaning tape and will be trying this solution as soon as it arrives in the mail.

I have the same problem. I have tried many cassettes and nothing works. Why does this happen?

THESE CAMERAS ARE PEICES OF ****!!!!!!!!!!!!!!!!!!
I suggest that no body buys from cannon again!!
I am suppose to record my sister-in laws wedding and BOTH of my ELURA 100's are displaying the EJACT TAPE message!

"TEMP. FIX"
This takes pateince however for me it works....When you get the EJECT TAPE mesage....eject the battery with the power on (thus the power will go off by means of the battery not being in camera) then slap the battery back in....and KEEP doing this untill eventually the camera will NOT DISPLAY the message and actual work.

It may take up to 20 trys ....slap it in..slap it out...slap it in slap it out...BUt for me it works.

If it appears to work but as you hit the RECORD button it beeps and displays the EJECT tape message again...Go back and eject the battery again and repeat the STEPS...but dont worry , that means your getting closer to it working.. LOL

P.s- I hate CANON

I had the same problem with my Elura 100. The problem started happening a few months after the warranty expired. I tried connecting to AC power only; this worked only once. I've only ever used TDK tapes (10 tapes recorded). The problem I was having was the tape never ejected. I've never dropped it or exposed it to water. The only solution that worked (which is similar to #2 above) was to open the cassette bay and leave the unit next to my laptop fan/exhaust for ~2-3 hrs. So far, so good. Thanks Donjr!

By the way, my local Canon repair shop was going to charge me $160+tax (CDN) to fix it.

Seconding Charpy Man's hack. Mine is an older Elura. It struck me as risky, but in fact worked like a charm after only two attempts at yanking the battery. In my case, I was yanking the power supply when plugged in, but the result was the same: when presented with the "eject" notice, I ejected the tape, I pulled the power, shutting the camera off immediately and unceremoniously. I then popped the power supply back on, inserted the tape, and got the eject message again. But when I repeated, suddenly, all was well.
Thanks, Charpy Man.
