Question 2

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 4

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 5

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.

Installation: Insert the adapter into the USB port of the printer while it is powered on.
Network Configuration: Use the navigation buttons on the printer to access the network settings or wireless connection menu.
- Select your Wi-Fi network.
- Enter the network password if necessary.
Wireless Printing: Once connected, you can print directly from a smartphone, tablet, or computer via the Canon app or your device's wireless printing functions.

This solution allows you to use the SELPHY CP800 via Wi-Fi despite the absence of this built-in feature originally.

Question 7

How to use the Canon SELPHY CP800 photo printer?

Accepted Answer

The Canon SELPHY CP800 is a compact photo printer using dye thermal sublimation technology. Before you begin, make sure you have purchased a paper kit and a color ink cartridge sold separately (available kits: KP-36IP, KP-72IN, KP-108IN for postcard and L-size, KC-36IP and KL-36IP for credit).

Initial setup: Unpack the printer and place it on a flat, stable surface. Plug the power cord of the AC adapter (CA-CP200 W provided) directly into the printer, then into an electrical outlet. Only use the recommended power source. No battery is provided (the NB-CP2L battery is optional). Press the power button to turn on the printer. The 2.5-inch tilting LCD screen lights up to guide you.

Installing the ink cartridge and paper: Open the front compartment of the printer. Insert the ink cartridge by gently guiding it until it clicks into place. Check the paper size on the feed tray (postcard 148x100 mm, L 119x89 mm, or credit 86x54 mm). Remove the protective sheet if present. Insert the paper into the feed tray with the glossy side facing up, not exceeding 18 sheets maximum. Never touch the glossy surface with your fingers. For credit size, fold the paper at the stamp line. Close the compartment.

Selecting images and printing: You can print in three ways: directly from a compatible memory card (SD, SDHC, CF, MicroDrive, Memory Stick, MMC) inserted into the printer's card reader, via USB from a computer (PictBridge), or from a compatible camera. Use the touchscreen to navigate, select a single image, or use the included SELPHY Photo Print software to select multiple images to print in one operation. The screen displays the print areas for different formats.

Print settings and options: The printer offers several effects and options: red-eye correction, image optimization, sepia conversion, black and white printing. You can choose between different layout formats (single image, 2-up, 4-up, 8-up) and ID card printing. Print speeds are approximately 47 seconds for postcard, 39 seconds for L-size, and 24 seconds for credit card, at 300 x 300 dpi with 16.77 million colors.

During printing: Keep the outer cover open. The paper enters and exits the printer several times during the thermal sublimation process. Do not remove the paper until the printing is completely finished. The photos are automatically ejected into the output tray at the front. Wait a few seconds after ejection before handling the photos to avoid damaging the protective coating.

Important points: Only use the special Canon paper provided in the official kits; never use standard paper. Do not exceed 18 sheets per load to avoid jams. Do not bend or separate the paper at the perforations before printing. If you need to stop a print in progress, press the cancel button. For portable use, the optional NB-CP2L battery allows you to print approximately 54 postcard sheets per charge. Printed photos offer a longevity of up to 100 years if kept in an album.

Reinsert the cassette correctly: Once freed, place the cassette back ensuring it is properly aligned and locked in place.
Close the cover and turn the printer back on: Check that everything is in place and then turn the device on to resume printing.

Tip: If the cassette remains stuck despite these actions, avoid using excessive force to prevent damaging the printer. In this case, it may be necessary to contact a specialized technical service for further assistance.
