Fusing unit pressure adjusting levers
In some cases damage to the envelopes, colour deviations, or smudging may occur even if envelopes within the
specifications are used. This problem may be alleviated by shifting the fusing unit pressure adjusting levers from their
"normal pressure position" to the "lower pressure position". Follow the procedure on the this page.
