Retarder pressure release button.
When you press the button and turn the wheel it should turn freely in one direction.
When you release this button you should feel the rubbing of the retarder against the feed wheel. This
should be a slight drag.
If the retarder adjustment is incorrect, insert the provided 9/64” hex wrench into the adjustment hole.
Turn the wrench clockwise to loosen, counterclockwise to tighten.
If the adjustment is incorrect you may have an Error 101 or Error 111 displayed.

If you put one finger on each side of the retarder as shown, you should adjust the retarder pressure so
the retarder just stops rocking. If the retarder is loose it will rock slightly. You want an even pressure
against the feed wheel.
Top sheet pre-fed
When the retarder is adjusted correctly you can press test and the machine will feed two sheets. After
the two sheets are fed the machine will stop. The top sheet will then be pre-fed into the machine
approximately ¼”. You can adjust the retarder until you get this results.
