Printheads [Oscillating vs. Spinning Polygon Mirror]
You need to be aware that there are differences in these two types of printheads. Both the alignment
procedures for each type of printhead, as well as the basic diagnostic
steps are different. This printhead
has an alignment procedure that is shown in the next section.
T650 & T650n
The T650 & T650n use an oscillating printhead and uses bidirectional printing. This printhead has a
tuning step in addition to the alignment procedure during installation.
T652dn & T654dn
The T652dn & T654dn use a spinning polygon mirror printhead, as did the T64x. This printhead is 40%
larger than the oscillating printhead and uses unidirectional printing. This printhead has an alignment
procedure that is shown in the next section.
