NovaJet 500/630/700 Series Service Manual
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.

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

deadband test is performed for the 500 series printers. Select
“Deadband Test” to run the deadband test.
