Test Patterns: 82E2000 (A3 and 11x17) 82E2010 (A4) 82E2020 (8.5x11).
Procedure
Make 5 copies of the test pattern,
through the centre of a solid area. Use a finger to apply medium pressure along the fold to
crease the paper. Unfold the copy. Use a finger to lightly rub the area of the fold and adjacent
areas.
Specification
Any break should measure less than 1mm (1/32 inch) across the line of a fold. Any area
rubbed with a cloth should not smudge or the image lift off the surface of the paper. When
checking the fusing on heavyweight paper (200gsm), rub the image with a finger. Images fused
on the smooth side of the paper have a greater resistance to rubbing than images fused on the
rough side of the paper. Do not attempt to fold heavyweight paper, as this breaks the fibres.
Corrective Action
If the fusing specification is not met, perform the
