5-6 Packet Reference Manual
Determining How to Store the Image
Once you have mapped out your graphic image, determine how to store it:
♦ Flash
♦ Volatile RAM
♦ Temporary Storage
Using Flash
Use flash memory when the graphic image is used by several formats, because the graphic only
has to be sent once. This eliminates the need to send the graphic image repeatedly. See “Placing
the Graphic in a Format,” for more information about using the graphic packet in a format.
Format flash memory before you can use it. From the Main Menu, select Setup, Flash Memory,
then, Format Flash. The process takes a few minutes. Graphics stored in flash memory are
saved when the printer is turned off. You may need to clear flash memory, refer to your
Operator’s Handbook.
Using Volatile RAM
You should use RAM when the graphic image is used by several formats, because you only have
to send the graphic image once. This eliminates the need to send the graphic image repeatedly.
See “Placing the Graphic in a Format,” for more information about using the graphic packet in a
format. Store graphics smaller than approximately 1/2 inch by 1/2 inch in printer RAM and
reference by the graphic ID number.
Note: Graphics are stored in the format buffer and remain there until another graphic packet is
sent or the printer is turned off.
Using Temporary Storage
You should use temporary storage when the graphic image is used only in one format or your
graphic image is very large. Graphic data in temporary storage is held in the image buffer until
the graphic is printed and then it is cleared from memory. Temporary graphics are also cleared
from memory when you send a new batch or update batch. You can use the same graphic image
multiple times on a format. Send the graphic image to the printer after the format to which it
applies.
If a graphic is stored in temporary storage, do not place a graphic field in the format. This causes
an error. Instead, position the graphic image by using the row and column locations in the
graphic packet header. Image memory (temporary storage) accepts a graphic packet 1218 rows
long with 811 dots per row.
