1. Wojambulayo amagwiritsa ntchito makhalidwe omwe angakhalepo a optical conductor kuti azilipiritsa optical conductor popanda kuwala, kotero kuti pamwamba pake amatsukidwa mofanana, ndiyeno kupyolera mu mfundo ya kujambula kwa kuwala, chithunzi choyambirira chikuwonetsedwa pa optical conductor.

2. Gawo lachifaniziro silinawunikidwe, kotero pamwamba pa woyendetsa kuwala akadali ndi malipiro, pamene malo opanda fano amawunikiridwa, kotero kuti malipiro omwe ali pamwamba pa woyendetsa kuwala amadutsa pansi pa gawo lapansi, kotero kuti mlandu pamwamba kutha, motero kupanga electrostatic zobisika fano.

3. Kupyolera mu mfundo ya electrostatic, tona yokhala ndi polarity yotsutsana imagwiritsidwa ntchito kutembenuza chithunzithunzi cha electrostatic chobisika pamwamba pa kondakitala wa kuwala kukhala chithunzi cha tona pamwamba pa kondakitala wa kuwala. Kupyolera mu mfundo ya electrostatic, chithunzi cha tona pamwamba pa kondakitala kuwala amasamutsidwa pamwamba pa pepala kukopera kuti amalize ndondomeko zofunika kukopera.
