Overview

Vertical bands in halftone images

Vertical bands of uneven image density may appear in halftone images on the rear side of duplex copies/prints when printing onto coated paper in low-temperature, low-humidity environments (10°C, 15%).

Uneven density in the area 85mm from the trailing edge

Uneven density in halftone images may appear in an area 85mm from the trailing edge, which corresponds to the point where the paper leaves the registration rollers.

Grainy image

The image density is not uniform across image areas when printing onto paper that is not smooth in high-temperature, high-humidity environments (27°C, 80%).
