IMPROVED BELT CONTROLS FOR A PRINT ENGINE FOR COLOR ELECTROPHOTOGRAPHY

摘要

In a print engine for color electrophotography using a photodetector belt (11) and a seamless transfer belt (12) on which a composite image is built up, the two belts are synchronized. Synchronization of the two belt drives enhances image registration. A tension mechanism used in conjunction with the belts prevents rapid changes in the belt dimensions. A transfer belt cleaner system (40) is synchronized with the belt drives such that excess toner is not left in the imaging area of the transfer belt.
