Lexmark confidential until announce edited 1/4/2007 7100-XXX Step 6: Clean/Erase There are two main cleaning processes that take place during the EP Process. One process cleans the photodeveloper and the other cleans the transfer unit. Photodeveloper clean/erase After each plane of color has been transferred to the transfer unit from the photodeveloper, a cleaning blade scrapes the remaining toner from the surface of the photodeveloper while an erase lamp discharges the remaining voltage. This is the clean/erase process. The photodeveloper surface is prepared to begin the EP cycle once again. This cleaning/erasing cycle happens after each plane of color is transferred to the transfer unit. Look at callout 6 in the picture below. This is where the photodeveloper is cleaned and erased in the photodeveloper phase of the clean/erase step of the EP process. Diagnostic aids 3-17
