Solid inks
Solid inks, sometimes called phase-change inks, are solid at room temperature
and are liquid at the higher temperature used during printing. The inks solidify
almost instantly after being jetted onto the printer’s drum. Because Tektronix'
proprietary solid inks bleed much less than ordinary liquid inks, they allow the
printer to print brilliant colors on plain paper.
Note Turning the printer off and allowing it to cool causes it to perform a
printhead cleaning and purge cycle upon power-up. The printer's
purge cycle consumes a significant amount of ink. During normal use
and servicing, turn the printer off and allow it to cool only when
necessary.
Memory considerations
There are four basic printer configurations. With the addition of the “Extended
Feature” ROM SIMM, the printer receives 69 on-board fonts, Check Print and
PhaserMatch capabilities. More RAM gives the printer job-pipelining and print
collation capabilities.
