How the Image Bands Command Works

The image bands command controls the amount of memory allotted to the
imaging process. When you increase the image band adjustment to a higher
number, you add more buffers to the imaging memory. By doing this, more
of the label format is imaged before printing begins.
The minimum number of required image bands is dependent upon the print
speed and the complexity of the label. Labels that contain numerous fields
with different rotations, graphics, or combinations of any number of these
formatting options may require a higher number of image bands.
To set the number of image bands, use the <SI>I command. See the Number
of Image Bands, Set command in Chapter 6 for more information.

Optimizing Print Speed and Image Band Setting

The maximum number of image bands available for use is 10 bands with
256K of static RAM or 20 bands with expanded memory. The minimum
number of image bands available is 2.
To optimize the number of image bands for your print speed
1. Set the image band setting at the lowest number (2).
2. Print a label at the desired speed.
3. Return to the original print speed and increase the original number of
7-12

If the label prints, the image band setting is optimal. You do not need to
perform any more adjustments.
If the number of image bands is too low, the printer aborts the label
before printing is completed and attempts to reprint the label at the
slowest speed (2 ips) with the highest number of image bands (9). You
need to continue with Step 3.
image bands one at a time.
Continue to increase the number of image bands until the printer prints a
label correctly.
