2.3.1.2 Main Control Circuit Board (C533Main) for EPL-6200L
EPL-6200L employs a newly developed controller for ESC/PageS Printing System.
PRINCIPAL FEATURES
„
All the functions, including those of the CPU, are incorporated in one ASIC
(called “SLC2”).
„
As the CPU core, C33 core made by EPSON is employed.
„
The algorithm of the extension circuit is BitRepeat3.
„
This controller is a fruit of the full pursuit of cost reduction:
2 MB of RAM (SDRAM is used), no optional RAM, no RITech and PGI
(EnhancedMicroGray), and resolution fixed to 600 dpi
„
Parallel interface (Nibble, ECP) and USB 1.1 interface
