Image Data
The actual image data encoded with JBIG image compression.
STUFF
Image data is a variable, so STUFF:0 (zero) is adjusted by continuous sending so that
the image data can be arranged into byte units or word (2 byte) units.
SDNORM (Stripe data completion: 0x02)
Shows the completion of stripe data
ESC 0x02
SDRST (The reset at completion of stripe data: 0x03)
Shows the completion of stripe data. Everything including the study table and the
ATMOVE are reset.

NOTE
When the image data encoding is 0xFF, it is imperative to attach 0x00 after
the image data encoding 0xFF in order to distinguish ESC(0xFF).
