Question 1

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 3

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.
