Sažetak
The research results of the study conducted show the effect of the change in the voltage of the developing drum and the voltage of the squeegee roller, which in fact are the first and last part of the development process and this is subsequently one of the phases of indirect electrophotographic printing on the recycling mechanism and characteristics of recycled fibers. The substrates bases are woodfree uncoated paper and coated paper intended for LEP printing technology, with the purpose of achieving high quality double-sided printing. The results confirm a decrease in the specks count and a larger speck area on a handsheet prior to flotation, when increasing the negative voltage of the developing drum. The specks count is higher on the handsheet obtained by recycling prints on uncoated paper versus coated paper. A greater speck count is removed by the flotation of prints on uncoated paper (approximately 73%), unlike coated paper (approximately 28%). When dealing with non- deinked handsheets in the recycling of prints on coated paper a growing number of count specks was determined in spot size>5mm2 by increasing the negative voltage of the developing drum, which is not the case for recycling prints using a varying voltage of the squeegee roller. The results of both the brightness and the ERIC can be well incorporated in the domain of explaining the mechanism of monitored processes.
