When to Calibrate
The printer features several types of calibrations. Some should
be run routinely, others only when necessary:

jobs AutoTune (page 4-4) Automatic jet maintenance during
extended printing periods
When loading a new media (but not
when loading a new roll of the same
media); after changing the head
height Media Feed or media feed adjust-
ment during printing (page 4-9)
Media advance accuracy

image sensor cannot calibrate

when loading a new roll of the same

ual)
Linearization of colors
Note: For maximum accuracy, the
photodiode must be cooled by its
fan before reading color patches. If
the left UV curing lamp has been on
for longer than 10 minutes, the pho-
todiode cooling fan runs for 12 min-
utes before taking readings;
otherwise the fan runs for 7.5 min-
utes. The control panel displays a
countdown timer while the photo-
diode is cooling.
