zWhen manually feeding any type of print media, set the paper selection lever to the front position and lower the paper support.
Do not move the paper selection lever after loading paper in the
zsheet feeder.
This lever is different than the lever on a typewriter or dot matrix printer. You need not pull it forward to load paper. You set the paper selection lever to the front position only when loading envelopes or when manually feeding paper. If it is set to the front position when you are automatically feeding stacks of normal paper, the printer may feed multiple sheets or jam.
When the paper selection lever is in the back position, a lever inside the printer prevents the paper from advancing into the printer. When you move the paper selection lever to the front position, the lever inside the printer moves so that the single sheet being manually fed can advance
