Deadband Alignment (for 500 Series)
The deadband alignment is necessary to ensure that the output images
are being produced with the highest quality standards available while
using the ENCAD printer in a bidirectional mode.
This adjustment helps to compensate for any deviations that may have
become apparent due to the carriage speed and/or the type of media
loaded. Precise calculations are being performed to time the release of
the ink drop so that they land on the media at the correct location.
Differences in media thickness make the distance that the ink has to
fall vary and this variable needs to be compensated for in the calcula-
tions.
To perform the Deadband Alignment for the 500 Series printers
1. Select “Utility Menu” from the Main Menu. This brings up the
Utility Menu as shown in Figure 3-19.
2. Select the “Service Menu” from the Utility Menu. This brings
up the Service Menu as shown in Figure 3-23.
3. Select the “Calibration Menu” from the Service Menu.
4. The Calibration Menu is shown in Figure 3-24 and is where the
deadband test is performed for the 500 series printers. Select
“Deadband Test” to run the deadband test.
5. When the plot is complete, select “Deadband” at the Calibration
Menu. This brings up the options menu for the deadband
adjustment. This menu is similiar to the menu depicted in
Figure 3-21.
6. Observe the plot and using either “Prev Option” or “Next
Option”, rotate through the selections until the value you want
is selected. Press “Ok” to accept the selection and return to the
