printhead

However, this time, the ribbon runs along between the paper and the printhead.

If they are too close, the printhead will snag and tear the form.

Check the state of the printhead, removing ribbon debris carefully.

The printhead paints text and images onto the paper.

However, the printhead uses roughly the same basic technology as the one that prints on thermal paper.

Another layer of protective coating keeps it from sticking to the printhead.

Other annoying drawbacks of old ink jets involved the printhead mechanism.

"Printhead" even verifies this fact within its own lyric.

The printhead sprays the ink on a rotating, oil coated drum.

The daisy wheel spins out 36 characters a second, the dot-matrix printhead 200.

The printhead provides heat to the thermal transfer ribbon in the appropriate places and melts these areas down.

In the printhead a small reservoir of ink sits above a resistor that is heated to about 330 C.

And the DeskJet even caps the printhead automatically when the job is done.

Most printers have a setting for adjusting the distance between the platen and the printhead, the moving part that creates the image.

As the printhead moves across the paper, it transfers a dot of color to the paper whenever heat is applied.

The firmware then controls the printhead and creates physical ink output up to the marketed resolution.

This printhead uses a heat resistor to convert electricity into usable heat.

In the Tonejet printhead, an electric force is applied directly to the charged ink particles.

The Tonejet printhead is therefore a simple, nozzleless, open structure.

In fact, in direct thermal fax machines, the only moving part is the system that feeds the paper through the machine past the printhead.

Normal inkjets use heat to form a bubble of ink which is expelled through nozzles on the printhead.

Separating the ink storage from the printhead may also allow the tank to be refilled or replaced while a print job is in progress.

For this reason, many third-party ink manufacturers provide a guarantee and will pay for the replacement of a damaged printhead.

So, to take advantage of the chemical's ability to darken paper, the fax machine incorporates a printhead that applies heat in the right places.

To date, the most successful commercial application of microfluidics is the inkjet printhead.
