Solid Inks; Memory Considerations - Tektronix Phaser 340 Service Manual

Solid inks

Memory considerations

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.
Phaser 340. With a base memory configuration of 8 Mbytes, the printer delivers
300 x 300 dpi printing and features 1.5 Mbytes of virtual memory. With a
4 Mbyte upgrade (12 Mbytes total) the printer's virtual memory is increased to
3 Mbytes. A 16-Mbyte RAM SIMM can be installed in the Phaser 340, but it will
only recognize 4 Mbytes of the SIMM.
Phaser 340 Plus. With its total of 24 Mbytes, the Phaser 340 Plus can print
600 x 300 dpi, job pipeline 600-dpi images, off-load images from the host faster
than a base Phaser 340, store more downloadable fonts, improve imaging
performance, and increase the input memory buffer for the parallel port.
