Prepare the product and the paper to print the diagnostic sheet Turn on your product and wait until it is functioning. Then select the paper on which the diagnostic plot is going to be printed (you can reuse the diagnostic plot any time in the future, if it is saved carefully). Ideally, the diagnostic plot should be printed on glossy paper, and you are highly recommended to do that if you use your product mostly for scanning or copying photo originals (posters, pictures printed on glossy paper, etc). If you use your product mostly to scan or copy matte originals, then you can use any matte white paper to print the diagnostic plot. Please do not use recycled or tracing paper to print this plot. The size of the diagnostic plot is 610 × 914 mm (24 × 36 in). It can be printed on any 914 mm (36 in) landscape or 610 mm (24 in) portrait paper roll. You can also use a single sheet that is at least 610 × 914 mm (24 × 36 in). Once the correct paper is loaded, if this paper permits color calibration then we recommend colorcalibrating the printer (see Using your product).

is going to be printed (you can reuse the diagnostic plot any time in the future, if it is saved carefully).
Ideally, the diagnostic plot should be printed on glossy paper, and you are highly recommended to do

glossy paper, etc). If you use your product mostly to scan or copy matte originals, then you can use any
matte white paper to print the diagnostic plot. Please do not use recycled or tracing paper to print this
plot. The size of the diagnostic plot is 610 × 914 mm (24 × 36 in). It can be printed on any 914 mm
(36 in) landscape or 610 mm (24 in) portrait paper roll. You can also use a single sheet that is at least
610 × 914 mm (24 × 36 in).
