KX-P7105 / KX-P7110 Recommended Media Transparency: · To avoid damaging the printer, do not use ink jet transparencies. · Transparencies and adhesive material used on labels should be stable at 205°C ( 400°F ), the printer’s maximum temperature. · Re-using transparencies that have been fed through the printer once ( for example, after jams or if the transparency is ejected without being printed ) can reduce the life of the consumables and paper path components. · When using transpare

KX-P7105/KX-P7110 Cleaning: After transfer, residual toner remains on the drum surface, and for next printing, the residual toner reaches to the development area via charge and exposure. The charge level of the OPC corresponds to the white background is +900VDC, andthe bias voltage of the conductive roller is approx. +350VDC. Therefor the positively charged residual toner on the OPC drum is attracted and collected to the conductive roller. The charge level of OPC after exposure is +100VDC. So,th
