Epson service manual Main Control Circuit Board C533Main for EPL-6200L, Major Elements

As the CPU core, C33 core made by EPSON is employed. The algorithm of the extension circuit is BitRepeat3.

EPSON EPL-6200/EPL-6200L Revision A

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”).

„

„

„ 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
