The product stores all fax pages in flash memory automatically. After these pages are written into flash
memory, they are stored until the pages are sent to another fax machine, printed on the product,
transmitted to the computer, or erased by the user.
These pages are stored in flash memory, which is the nonvolatile memory that can be repeatedly read
from, written to, and erased. The product has 8 MB of flash memory, of which 7.5 MB is available for
fax storage. The remaining 0.5 MB is used for the file system and reclamation. Adding RAM does not
affect the fax page storage because the product does not use RAM for storing fax pages.
Stored fax pages
The user can reprint stored fax receive pages in case of errors. For a fax send, the product will resend
the fax in case of errors. The product will resend stored fax pages after a busy signal, communication
error, no answer, or power failure. Other fax devices store fax pages in either normal RAM or short-
term RAM. Normal RAM immediately loses its data when power is lost, while short-term RAM loses its
data about 60 minutes after power failure. Flash memory maintains its data for years without any
applied power.
Advantages of flash memory storage
Fax pages that are stored in flash memory are persistent. They are not lost as a result of a power
failure, no matter how long the power is off. Users can reprint faxes in case the print cartridge runs out
of toner or the product experiences other errors while printing faxes.
The product also has scan-ahead functionality that makes use of flash memory. Scan-ahead
automatically scans pages into flash memory before a fax job is sent. This allows the sender to pick up
the original document immediately after it is scanned, eliminating the need to wait until the fax
transmission is complete.
Because fax pages are stored in flash memory rather than RAM, more RAM is available to handle
larger and more complicated copy and print jobs.
