CHAPTER 1 III. BASIC OPERATION A. Outline To install an optional I/O device into the printer, the Paper Handling Controller must first be attached to the printer. The Paper Handling Controller uses an 16 bit micro computer (IC101) that controls serial communication with the Video Controller and serial communication with optional I/O devices. - Page 15 CHAPTER 1 B. Operations by Block 1. CPU (IC101) An NEC 1 chip micro computer (UPD784020GC-3B9) is used. The CPU communicates with the Video Controller and optional I/O driver, and controls the optional I/O devices. 2. EP-ROM (IC109) The EP-ROM has a 64K byte memory capacity, and contains the optional I/O device's operation control program.
