5.4.1 Data in the image storage memory (DRAM)

DRAM stores image data which was read other than by a direct transmission. It also acts as a buffer memory
to store the image data received. If power is turned off, the memory clear list is printed automatically the next
time the power is turned on. The user is thereby notified of the images that were erased from memory.
NOTE
SRAM (IC5)

Reception image data
This product is not equipped with image data backup, so that if the power supply is cut, data
in memory reception will be lost.
When image data are set to be printed, they will be stored in the DRAM as memory reception
images, and "REC'D IN MEMORY" will be displayed. If printing is disabled due to a fault
in the printing section, transfer the stored reception image data to another fax machine.
