1.5.2. Reception
FCU
LIF: Laser Interface
DCR: Data Compression & Reconstruction
MDM: Modem
Data from the line passes to the modem through the NCU. After the modem
demodulates the data, the decompressed data passes to the DCR block,
through the ECM memory, where the data is decompressed to raster image
data.
BRO only: At the same time, the compressed data passes to the SAF mem-
ory as a backup in case of mechanical problems during printing (substitute
reception.
The raster image data is then sent to the thermal head through the LIF block.
