Maintenance
1. Ink Tank Refilling
When an ink tank level is low, the printer's ink end sensor will indicate the need for a refill. Use genuine Canon GI-790 ink bottles to replenish the tanks. Refer to the "Ink Filling" section under Setup for the correct procedure.
2. Print Head Cleaning
If print quality deteriorates (e.g., streaks, faded colors), perform a print head cleaning. This can be initiated from the printer's maintenance menu on the control panel or through the printer driver software on your computer. Regular cleaning helps maintain optimal print quality.
3. Paper Jam Clearing
If a paper jam occurs, the printer will display an error message. Carefully open the printer covers and gently remove any jammed paper, pulling it in the direction of the paper path to avoid tearing. Ensure all paper fragments are removed before closing the covers and resuming operation.
