Zde je stru\u010dn\u00fd popis jej\u00edho fungov\u00e1n\u00ed: 1. Zpracov\u00e1n\u00ed dat: Po\u010d\u00edta\u010d rozd\u011bl\u00ed dokument na mal\u00e9 \u010d\u00e1sti dat, ne\u017e je ode\u0161le k tisku.

4.

Zapalov\u00e1n\u00ed toneru: Po p\u0159enesen\u00ed obrazu na pap\u00edr je obraz posl\u00e1n p\u0159es zap\u00e9kac\u00ed za\u0159\u00edzen\u00ed, co\u017e je sada vyh\u0159\u00edvan\u00fdch v\u00e1lc\u016f.
