accurately when moving in either left-to right or right-to-left direction. Manual Head
Registration aligns the printheads with each other in the X axis. See the printer’s
User Manual
for additional documentation of these procedures.
A common question that arises is whether there is an advantage to using a manual
calibration over an automatic one, or vice-versa. Both manual and automatic calibra-
tions have the same degree of precision, but the accuracy of manual calibrations
depends on the operator’s skill level. In general, the manual calibrations can be
performed faster (by a skilled operator) than the automatic versions. The automatic
versions, however, allow the operator to perform other tasks while the printer takes
care of itself. The printer also may be more consistent as it has a fixed set of rules
for interpreting the patterns, while an operator may vary his or her judgement based
on external factors. On the other hand, manual jet mapping has the additional advan-
tage of allowing the operator to judge when a jet is firing, but may not be firing in a
consistent manner. So there is no simple answer to this question.
