Thermal Inkjet Technology
Ink-jet technology centers on a disposable print cartridge, which propels ink out of 300
nozzles (192 nozzles on the color print cartridge). The basic principle is to apply heat to
a tiny measure of ink until it expands and is propelled through a nozzle. This is
achieved by first filling a small reservoir, known as the firing chamber with ink. The next
step is to heat the ink with a thin-film resistor layered above the firing chamber. As the
ink heats up, it expands to form a bubble. As the bubble continues to expand and burst,
it is forced through the nozzle located below the firing chamber. This process is
repeated up to 12,000 times per second.

Printing
1- Most printer problems are caused by using the wrong type of paper or using
paper that is wrinkled or damp. For best results, use paper that is made
specifically for Ink Jet printers with a paper-weight of at least 20 lbs.
.
2- To load paper, tap its edges on a flat surface to even it out. Then place the paper
into the tray with the top of the page facing down and away from you.
