Hi,
Googling to solve the same problem with my Power Shot G12, I found a manual under ManualOwl -- on p.194 it says:
"Communication error: images could not be transferred to the computer or printed due to the large amount of images (aprox. 1000) stored on the memory card. Use a commercially available USB card reader to transfer the images. Insert the memory into the printer's card slot to print."
This worked for me. Hope it does the same for you.

Try NOT connecting your camera to your computer.

The best way to transfer pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.

Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive, the same way you copy any other files. Or you can use any photo management program such as Picasa.

try either a card reader (rather than connecting your camera to the computer) or try erasing photos. it seems that it happend when the card is too full. i had the problem and had to go under 3000 photos and then it worked.

hope this helps.

Fully concur with Obertelli's solution. Here's a little more info on the external card reader method to download photos. Note that there are many advantages to using this method than downloading through your camera.

Hi,


I highly recommend that you instead consider using a card reader to move the photos or videos to your computer. Card reader's do not require software (although Windows 98 and earlier may require drivers), are very inexpensive, are much faster downloading files from the camera, do not use the camera's batteries during the download, and are much less prone to file corruption of the photos during the download.
Really, it would be better for the camera user if one of these was included with the camera instead of the cable and bundled software.
You place the camera's card in the reader, plug the reader into the USB port, and your computer sees it as a hard drive. You simply copy/paste or drag/drop your photos onto your hard drive. For this simplicity, most professional photographers utilize card readers exclusively. You'll save yourself a lot of heartache if you convert to using one of these. Also make sure that you get a reader that is clearly stated capable of reading your card, particularly if you use SDHC, XD, CF, or MS cards.


Thank you!

SOURCE: I receive a "communication error"

To address the present problem make sure the camera is off before plugging in the cable either to the computer or the camera. Also make sure the batteries are up to charge, low batteries or batteries that fail during file transfer will corrupt the memory card. With batteries up to charge plug the cable into the camera and the other end into a USB port and turn the camera on. Now, I would like to suggest that you invest in a memory card reader these are fairly inexpensive and can be bought as a single reader for the type of memory card you have or as a multiple card reader for pretty well every memory card that's on the market. To use a Card Reader it plugs into a USB port and the memory card is removed from the camera and inserted into the card slot. The computer recognizes this card reader as an external hard drive and files can be transferred to your computer Hard Drive with ease. One thing you must remember with any external device and that is you need to do a safe disconnect or eject make sure the device is shut off and the file information is downloaded before you remove the memory card or the files/card can become corrupt. Okay once the transfer is completed insert the memory card back into the camera and format the memory card. Don't delete the pictures at this point Format the memory card. Every time you download the pictures to the computer Format the memory card.

I have a Canon PowerShot G9 camera. When i plug it into usb cord to dowload pictures, i get the error message "Communication Error" across the viewing screen of the camera.


The problem I believe is the sequence or flow of the connection.
With the camera turned off. Connect the USB cable to a computer USB port and the other end to the camera digital port turn the camera on by using the "Playback" button here is a diagram

You know there is an easier and better way of transferring picture files and that's by using a memory card reader. A memory card reader plugs into the USB port of a computer and the camera memory card is inserted into the reader slot. The computer then looks at this as an external Hard Drive. Both methods will need you to format the memory card after the images have been downloaded to the computer. Formatting the memory card in the camera in which it is to be used will clean the card and making it compatible with the camera both the camera and memory card can then communicate without errors.

Sony cybershot P200 says 'File Error'


Hi,

The LCD screen may display a FILE ERROR message when trying to view a still image on the camera if the image was rotated, modified and overwritten using editing software on a computer. To play images you have taken on the camera, it is recommended that you do not make any changes to the original image files. I suggest that you transfer the images from the Camera to the computer and check if it works. After transferring the images, get the Memory formatted from the Camera and start capturing new images. The edited images will not get displayed in the Camera again. Please try not to edit the images in the Computer without transferring it.


Thanks.

Troubleshooting the camera displaying Communication Error when connected to the computer via USB. If the camera displays "Communication Error," when trying to download images the main cause for this error is that there are more than 1000 images stored on the memory card. It is recommended if there are more than 1000 images on the memory card, that you use a card reader to acquire the images, or to delete images off of the memory so that there are less than 1000 images to download from the memory card.
If this is not the case, there are not 1000 or more images on the memory card, try reconnecting the camera to abnother port on the computer, try another cable or another computer. This error can also display when connecting to a direct print printer. Please check with the printer manufacturer for more information on this error.

Canon zoombrowser Ex downloading problem


Try updating the Zoombrowser software.

If you have a connection to the camera, go into my computer and get images directly off the camera using scanner and camera wizard, microsoft's default program. This will at least allow you to transfer your images until you can resolve the software problem.

If you have no connection to the camera via your computer, you need to try some other troubleshooting steps to get a connection. I will post those below in the next post.
