5.3.10.2.8 E RASE S ELECTED F LASH S ECTOR
Erases the previously selected sector. The printer transmits ACK when the sector has been erased. If the
previous sector is not successfully erased, or if no sector was selected, the printer transmits NAK.

5.3.10.2.9 D OWNLOAD TO A CTIVE F LASH S ECTOR
Contains a start address (ah x 256 + al) and count (ch x 256 + cl) of binary bytes to load into the selected
sector, followed by that many bytes. The start address is relative to the start of the sector. Addresses run
from 0 to 64K.
The printer may return one of several responses. ACK means that the data was written correctly and the
host should transmit the next block. NAK means that, for some reason, the data was not written correctly.
This could mean that communications failed or that the write to flash failed. The alternatives seem to be to
retry the block or halt loading and assume a hardware failure.
