PRINCIPLES OF OPERATION
Image Buffer
The image buffer has two lines at 360 DPI (including half dots). One line is used for data output, and the other
is used for developing the image data. The image data is output when an interruption is made by the SOFTI.
Figure 2-60 shows the image buffer structure.
Queue Buffer
The queue buffer is used for controlling the paper-feed operation. With the INTEO interruption, paper is fed
automatically according to the contents of the queue buffer. Figure 2-61 shows the queue buffer structure.
