Gener al print media guidelines

• Paper types you cannot use Do not use the following: –Creased print media –Curled print media –Wrinkled print media –Moist print media –Print media that is too thin (It should be at least 17 lb.or 64 g/m –Print media that is too thick (It should not be more than 28 lb.or 105 g/m

Canon print media.) –Print media with holes (e.g.punched holes) –Postcards with photographs or stickers adhered to them

• Hold the print media as closely as possible to its edges and try not to touch the printing surface. Printing quality will deteriorate if the printing surface is damaged or becomes dirty.

• Do not touch the printing su rface until the ink has drie d.

• Some print media ma y curl and the printing surface ma y smudge if you ha ve used a larg e amount of ink for printing.If this occur s ,move the paper thickness leve r to the right.Paper that tends to curl is not recommended for printing photographs or graphics.Use fo r printing mainly text .

• Do not use print media that is in bad condition ( abo ve).If the print media is curled, uncurl it before printing.

• Place the print media you have not used back into its packet and store out of direct sunlight in a place where temperature and humidity is low.

• Photo P aper Pro guidelines –Do not touch the printed su rface until the ink is fixed (approx .30 minutes). C olors in dar k

images may appear indistinct at first,but will become clearer after about 30 minutes.

–Images ma y smudge if you place them in an album bef ore the ink is completely dry.It is

recommended that you allow the ink to dry f or 24 hours.

–Do not attempt to dry the ink with a haird ry er or by exposing printed sheets to direct

sunlight.

–Do not store or display printouts in hot,damp,or humid conditions .Never expose them to

heat or direct sunlight.

–Store printouts in photo albums,photo frames,o r presentation binders to protect them

from direct exposure to air or sunlight.

–Do not mount printouts in an adhesive-type album as you may not be able to remove

them.

–Be aware that some types of clear plastic folders and albums may cause the edges of the

paper to turn yellow.
