Summary Objective: produce a imaging system that is capable of capturing ink drops on the drum and on the paper at identical locations Current System: clumsy to use, vibrates excessively, and the optical system fails to meet the desired image quality Current System: clumsy to use, vibrates excessively, and the optical system fails to meet the desired image quality There is no specific imaging system that compares the drum images to paper images There is no specific imaging system that compares the drum images to paper images

Summary

Summary Oil is transferred from the maintenance roller to the drum before ink is transferred by the print head Ink transfer from drum to paper as the paper feeds between the transfix roller and drum
