Question 6

How to resolve the error message "unsupported USB connected device" on the Canon SELPHY CP780 printer?

Accepted Answer

The error message "unsupported USB connected device" means that the Canon SELPHY CP780 does not recognize the type of device or peripheral connected. This issue is generally related to device incompatibility or a misconfiguration of the connection.

Steps to resolve the issue:

Make sure you are only connecting one device at a time. The printer cannot be connected simultaneously to a camera, a computer, and a memory card. Disconnect all USB devices except the one you wish to use, then reconnect the SELPHY printer.
Use an appropriate USB cable. Ensure that you are using a compatible type B USB cable for connection to a computer, or a type A USB cable for connection to a PictBridge compatible camera. A faulty or unsuitable cable can cause this error.
Do not connect via a USB hub. The SELPHY CP780 printer does not function properly when connected to a computer via a USB hub. Plug the USB cable directly into a USB port on your computer or into the USB connector of your camera.
Check the camera compatibility. If you are connecting a camera, make sure it supports the PictBridge standard. Refer to your device's manual to confirm this compatibility. Only memory cards with an adapter and PictBridge devices are recognized on this model.
Disconnect other USB devices. Unplug any other USB devices from your computer (except USB mouse and keyboard). Other USB devices may interfere with the printer's recognition. Once disconnected, reconnect the SELPHY printer.
Restart the devices. Completely turn off the Canon SELPHY CP780 by holding down the q button, then turn it back on. Also turn off the connected computer or camera, wait a few seconds, then turn it back on. Then reconnect the USB cable.
Check the file format. If you are printing from a memory card, ensure that the image files are in JPEG format, which is the only format supported by this printer.
If the problem persists. Turn off the printer, wait 30 seconds, then turn it back on. If the error message continues to display after following all these steps, contact Canon support.

Question 8

Why does my CANON SELPHY CP760 photo printer only print on the upper half of the paper?

Accepted Answer

If your CANON SELPHY CP760 photo printer only prints on the upper part of the paper and leaves the lower half blank, it may be due to several causes related to the paper, print settings, or the printer itself. Here’s how to resolve this issue:

1. Check the paper used

Make sure you are using photo paper compatible with the SELPHY CP760, typically Canon-specific photo paper for this printer.
Check that the paper is correctly loaded in the tray, with the glossy or print side facing the correct direction according to the tray instructions.
Avoid using crumpled, folded, or damp paper that could disrupt the paper feed.

2. Check the print settings

Ensure that the paper size selected in the print settings exactly matches the size of the loaded paper (for example, 10x15 cm).
Make sure that the image format or layout does not limit the print area to the upper half.
If you are printing from a computer or mobile device, check that scaling or cropping options are not incorrectly enabled.

3. Cleaning and maintenance of the printer

Perform a print head cleaning via the printer menu to remove any blockage that may cause incomplete printing.
Check that the ink ribbon is properly installed and in good condition, as a worn ribbon can lead to partial prints.

4. Other tips

Restart the printer to reset its system.
Try printing another photo or a test print to see if the problem persists.
If the problem continues, it may be a hardware defect requiring technical intervention.

By following these steps, you should be able to identify and correct the cause of the limited printing to the upper half of the paper with your CANON SELPHY CP760.

Question 9

Why doesn't the screen of my Canon SELPHY CP720 printer display the photos from my USB drive?

Accepted Answer

If the screen of your Canon SELPHY CP720 printer does not display the photos stored on your USB drive, several causes may be behind this issue. Here are the points to check to resolve this situation:

1. Check file compatibility

Make sure that the photos on your USB drive are in a format supported by the printer, particularly the JPEG format (.jpg). Incompatible formats will not be displayed.

2. Check the format of the USB drive

The Canon SELPHY CP720 printer generally recognizes USB drives formatted in FAT32. If your drive is formatted in NTFS, exFAT, or another file system, it may not be detected correctly.

3. Check the insertion and condition of the USB drive

Ensure that the USB drive is properly inserted into the printer's USB port.
Try removing and reinserting the drive to ensure a good connection.
Test the USB drive on a computer to verify that it works normally and that the photos are accessible.

4. Examine the size and number of files

Files that are too large or a large number of photos may slow down or prevent display. Try with a few smaller photos to see if they display.

5. Restart the printer

Completely turn off the printer, wait a few seconds, then turn it back on. This can resolve some temporary malfunctions.

By following these steps, you should be able to display your photos on the screen of your Canon SELPHY CP720 via your USB drive. If the problem persists, it may be helpful to test with another USB drive or check if a firmware update is available for your printer.
