FIT (image FITting) flashes to indicate that a loss of raster data
occurred when the data was compressed to be fitted within the
currently available memory. Flashing FIT extinguishes automati-
cally when the job times out; the printer receives the next data
from the host computer; or if you press any key on the printer's
control panel. Try adding more memory in the printer to prevent
this error.
Change of the resolution indicator from 600 to 300 (flashing)
means that the job in 600-dpi resolution was not able to run
within the currently available memory. The resolution reverts to
600 dpi automatically when the job times out; the printer receives
the next data from the host computer; or if you press any key on
the printer's control panel. Try adding more memory in the printer
to prevent this error.
