Ma evo pokusavam sa ovim ali ne ide nikako ne uspijevam ga resetovat.

Vjerovatno zbog toga sto ne poznajem bas najbolje englesni pa mozda pogrijesim u koracima, ili sta drugo ja ne znam.

Jer ne mogu ja uopste uc u ovaj ''service mode''.

kad bi mi neko pojasnio ukratko tih par koraka da mogu uc u ovaj dio poslije bi se valjda snasao.

I mislim da je bas do kertridza jer se memi problem javio tek nakon sto sam promijenio kertridze, dok je prije toga sve bilo u redu.

Obicno se uredjaji ukljucuju tako sto drzis to dugme stisnuto jednom rukom a drugom ukljucis power dugme.Vidi kako google translator prevodi:
1) Uz štampač isključen već priključen na izvor napajanja, pritisnite Pover taster pritisnite i držite
STOP / RESET dugme.
2) Kada LED svetli, pritisnite taster STOP / RESET taster dva puta pritisnite i držite taster za uključivanje.
3) Kada se izveštava i Pover taster STOP / RESET dugme (bez obzira na redosled), štampač će se prebaciti u
servis mod. (Čekanje formenu izbor)
4) Kada LED svetla u zeleno, pritisnite Stop / Reset taster određenom broju Time (s) prema
funkcije navedene u tabeli (Svaki put STOP / RESET dugme je pritisnuto. LED svetla naizmenično
narandžasta i zelena, počev od narandže.)
