Canon MP25DV adding machine high pitch noise

[rsccpa]

I just purchased probably my fifth Canon MP25DV over the last few years and this one is emitting a almost constant high pitch noise which is very annoying.  None of my other adding machines have ever done this.  It's going back to Staples tomorrow.  Has anyone else had an adding machine that has done this? 

I thought I could live with it but it is driving me crazy!

Same problem with MP11DX purchased last month. The whine goes away for a while if you shut it off & turn it back on. I am not sure if it happens when the unit is on for a while and gets warm, cause it doesn't happen first thing in the a.m. Took me two weeks to figure out what was causing the noise in my office!!

It didn't make that maddening sound for more than a year after purchase. I originally thought I had tinnitus and thought I was going crazy. It wasn't until I had a co-worker come over and help me figure out the sound that I discovered it was the calculator in sleep mode.

This is my favorite calculator and have used this model for years!  I am returning this new one TODAY because of the high pitch noise it emits when it goes into sleep mode.  1st I do not need a 7 minute sleep mode setting.  I get interrupted constantly and this is a total PAIN!

Completely agree. Love the touch of this model but the sleep mode is unneeded. Worse yet, is that the sleep mode activates the high pitch squealing sound that's loud enough to drive one mad. It didn't make this sound for about a year plus after purchase so it's past warranty.

I have Canon MP11DX and this is my 4th one like this. I love this machine, however, this high pitched squeel has got to go or the Canon is out of here. Mine is past warranty too. If I can't get an answer and solution to this problem, the next time I'm out, I'm getting another brand.

Hi there,

I'm sorry to hear about the issue you're experiencing with your new Canon MP25DV. It's not a common problem, but it does sound very frustrating.

The high pitched noise could be due to a variety of factors, including an electrical issue or a mechanical problem within the device. Here are a few troubleshooting steps you can try before returning it to Staples:

Power Cycle the Adding Machine: Unplug the machine, wait for a couple of minutes, then plug it back in. Sometimes a simple power cycle can resolve minor electronic glitches.

Inspect for Visible Damages: Ensure there's no visible damage to the adding machine that may cause the noise, such as a loose part.

Check the Power Supply: The noise could potentially be caused by an issue with your electrical supply. Try using the machine in a different location or on a different power strip to rule out this possibility.

I have tried all of your ideas and I get no changes. It's a malfunction in the calculator no doubt. I say this because I can turn it off, it still has the high pitched sound. However, when I turn it on to the first right, it stops. I can then turn it all the way to print and within 10 minutes we've got the whistle again. It's getting on my nerves and I can't keep turning it on and off every 10 minutes. This is the 3rd one I've had that does this and unless you can give me a solution, I'm going to try another brand.

I also have had the problem with my MP11DX.  I tried all your suggestions as well.  My 1st MP11DX didn't start making the noise for several years.  It was my favorite calculator as well.  The noise was madding. You just had to keep hitting the CE button to awake the machine and it will stop.  It was too much for me.  I replaced it with another brand.  I was not as happy with it.  I did finally purchase another MP11DX.  It started the noise within several days.  Again, it only makes the noise in sleep mode or if you turn it off.  Although, I have noticed that if I turn off the machine before it goes into sleep mode, it will not buzz.  I am very disappointed that such a great calculator is so annoying with this buzz.  I guess I will not be buying any Canons again. Please fix this issue.
