Video: covering the printhead nozzles with a rubber cap. The primary cause of inkjet printing problems is ink drying on the printhead's nozzles, causing the pigments and dyes to dry out and form a solid block of hardened mass that plugs the microscopic ink passageways.
As 1200 bit/s dialup communication became more common among Time-sharing providers, the Silent 700 faced the problem that its printhead technology simply couldn't "heat up all the little dots" at 120 characters per second. TI solved this in their 780-series terminals by creating a two-character-wide thermal head, which printed 60 pairs of ...

A Thermal transfer printhead jets the liquid ink on a rotating, oil coated drum. The paper then passes over the print drum, at which time the image is immediately transferred, or transfixed, to the page. Solid ink printers are most commonly used as color office printers and are excellent at printing on transparencies and other non-porous media.
In 2007, PC World reported that refilled cartridges have higher failure rates, print fewer pages than new cartridges, and demonstrate more on-page problems like streaking, curling, and color bleed. [29] Therefore, product or service research is often recommended. [30]
Actual position can be found out either by dead count using a stepper motor, rotary encoder attached to one wheel, or a transparent plastic band with markings that is read by an optical sensor on the printer head (common on inkjets). Because the printing involves mechanical pressure, dot matrix printers can create carbon copies and carbonless ...
