Appendix Wavy or dry edges may cause misalignments in paper feeding. The recommended moisture content of paper is between 4 and 6 %. To maintain the correct moisture content level, pay attention to the following items. • Store paper in a dry, well-ventilated place. • Leave packages of paper wrapped as long as possible. Rewrap paper that will not be used soon after unpacking. • Store paper into its paper carton or packing paper with sealing. Place the cartons on a pallet or other furniture so that they are not in direct contact with the floor. Separate particularly from a boarded or concrete floor in the rainy season. • Before using paper stored for an extended period of time, keep it in a proper condition of water content for at least 48 hours. • Do not expose paper to heat, direct sunlight or damp. Grain Direction In manufacturing of paper, paper is cut with grain vertical to the paper length (long grain) or with grain vertical to the paper width (short grain). Since short grain paper may cause a problem in paper feeding, use long grain paper. Other Specifications Porosity: Indicates the density of paper fiber. Stiffness: Limp paper may buckle in the machine, resulting in paper jams. Curl: Most paper naturally tends to curl one way if left unpacked. When paper passes through the fixing unit, it curls upward a little. To produce flat printouts, load the paper so that the upward pressure from the machine can correct their curling. Electrostatic discharge: During the printing process, paper is given an electrostatic charge to attract the toner. Therefore, select the paper that discharges the static electricity immediately. Whiteness: The contrast of printed images depends on the whiteness of the paper. Whiter paper produces sharper and clearer images. Quality control: Uneven paper sizes, corners that are not square, jagged paper edges, irregularly cut sheets, torn edges and corners, etc. may cause malfunction of the machine. Be careful particularly when cutting paper by yourself for using it as copy paper. Packaging: Select paper that is securely packed and shipped in a carton. Packing paper coated inside for moisture proof is the best. Special treatment: It is recommended not to use paper with the following treatment even if the paper satisfies the basic specifications. To use such paper, perform trial printing before purchasing a large amount of paper. • Glazed paper • Watermarked paper • Paper with uneven surface • Paper with perforations Appendix-4

of paper is between 4 and 6 %.
To maintain the correct moisture content level, pay attention to the following items.
•
Store paper in a dry, well-ventilated place.
•
Leave packages of paper wrapped as long as possible. Rewrap paper that will not be used
soon after unpacking.
•
Store paper into its paper carton or packing paper with sealing. Place the cartons on a pallet or
other furniture so that they are not in direct contact with the floor. Separate particularly from a

content for at least 48 hours.
•
Do not expose paper to heat, direct sunlight or damp.
Grain Direction
In manufacturing of paper, paper is cut with grain vertical to the paper length (long grain) or with
grain vertical to the paper width (short grain). Since short grain paper may cause a problem in paper
feeding, use long grain paper.
