Error 1668 on a Canon printer typically indicates an issue with the ink cartridges. Here are some steps you can try to fix the error:
Check Ink Cartridges: Ensure that the ink cartridges are installed correctly and are not empty. Open the printer cover and inspect the cartridges. If any cartridges are empty, replace them with new ones. Make sure they are securely inserted into the printer.
Clean Cartridge Contacts: If the cartridges are not empty, remove them from the printer. Clean the electrical contacts on both the cartridges and the printer using a lint-free cloth or cotton swab lightly dampened with distilled water. Allow them to dry completely before reinserting the cartridges.
Restart Printer: Turn off the printer and unplug it from the power source. Wait for a few minutes and then plug it back in. Turn on the printer and check if the error has been resolved.
Reset Printer: Sometimes, a printer reset can help resolve various errors. Consult your printer's user manual or the Canon website for specific instructions on how to perform a reset for your model.
Update Printer Firmware: Outdated printer firmware can sometimes cause errors. Visit the Canon website and check if there are any firmware updates available for your printer model. Follow the instructions provided by Canon to update the firmware.
