Ink Safety Precautions

Keep ink cartridges and maintenance box out of the reach of children and do not drink the ink.
Keep the ink cartridges out of direct sunlight.
Store ink cartridges in a cool, dark place; do not store the ink cartridges in high or freezing temperatures.
Be careful when you handle used ink cartridges; there may be ink remaining around the ink supply port. If ink gets on your skin, wash it off with soap and water. If it gets in your eyes, flush them immediately with water. If you experience discomfort or vision problems after flushing your eyes, see a doctor immediately. If ink gets in your mouth, see a doctor immediately.
Do not dismantle an ink cartridge. This could damage the print head.
Do not disassemble or modify the ink cartridge or maintenance box; otherwise ink may get into your eyes or on your skin or you may not be able to print normally.
Do not shake cartridges too vigorously; this can cause them to leak.
Do not drop or knock ink cartridges against hard objects; this can cause leakage.
Do not remove or tear the label on the cartridge; this can cause leakage.
Use an ink cartridge before the date printed on its package or within six months of opening the package, whichever is earlier.
Store ink cartridges with their bottoms down. Do not store cartridges upside down.
After bringing an ink cartridge inside from a cold storage site, allow it to warm up at room temperature for at least three hours before using it.
Do not open the ink cartridge package until you are ready to install it in the printer. The cartridge is vacuum packed to maintain its reliability. Leaving a cartridge unpacked for a long time before using it may prevent normal operation.
Do not break the hooks on the side of the cartridge when removing it from the packaging.
Do not shake cartridges after opening their packages; this can cause them to leak.
You must remove the yellow tape from the cartridge before installing it; otherwise, print quality may decline or you may not be able to print.
Do not remove the transparent seal from the bottom of the cartridge. This may cause the cartridge to become unusable.
Do not touch the green IC chip on the side of the cartridge. This may prevent normal operation.
Make sure to install all ink cartridges. The printer only works when all ink cartridges are properly installed.
Do not replace ink cartridges with the power off.
Do not turn off the product during ink charging. If ink charging is incomplete, you may not be able to print.
If you remove an ink cartridge for later use, protect the ink supply area from dirt and dust and store it in the same environment as the product. Note that there is a valve in the ink supply port, making covers or plugs unnecessary, but care is needed to prevent the ink from staining items that the cartridge touches. Do not touch the ink cartridge ink supply port or surrounding area.
Install a new ink cartridge immediately after removing an expended one. Leaving cartridges uninstalled can dry out the print head and may prevent the product from printing.
Do not turn off the printer during cartridge replacement. Otherwise, ink remaining in the print head nozzles will dry out and you may not be able to print.
Do not put your hand inside the product or touch any cartridges during printing.
Removed ink cartridges may have ink around the ink supply port, so be careful not to get any ink on the surrounding area when removing the cartridges.

Ink Consumption

This printer uses ink cartridges equipped with a green chip that monitors information such as the amount of remaining ink for each cartridge. This means that even if the cartridge is removed from the printer before it is expended, you can still use the cartridge after reinserting it back into the printer. However, when reinserting a cartridge, some ink may be consumed to guarantee printer performance.
To ensure you receive premium print quality and to help protect your print head, a variable ink safety reserve remains in the cartridge when your printer indicates that it is time to replace the cartridge. Quoted ink yields do not include this reserve.
Quoted yields may vary depending on the images that you are printing, the paper type that you are using, the frequency of your prints and environmental conditions such as temperature.
Do not use the cartridges that came with the printer for the replacement. The ink in the ink cartridges supplied with your printer is partly used during initial setup. In order to produce high quality printouts, the print head in your printer needs to be fully charged with ink. This process consumes a quantity of ink and, therefore, these cartridges may print fewer pages compared to subsequent ink cartridges.
To maintain optimum print head performance, some ink is consumed from all ink cartridges during maintenance operations. Ink may also be consumed when you replace an ink cartridge or turn the printer on.
When printing in monochrome or grayscale, color inks may be used instead of black ink depending on the paper type or print quality settings you are using.
