The EPSON Stylus COLOR 3000 is a high-performance color ink jet printer designed for the office market as well as for plotter use with a wide paper availability up to full A2 size.
The adjust lever, located at the right and upper side in the printer cover, is used to adjust the gap between the paper and platen. The adjust lever must be set to the proper position according to the paper type to avoid ink smudging caused by ink’s contact with paper. The EPSON Stylus COLOR 3000 is equipped with the parallel and Mac serial interfaces and a card slot for an optional Type-B interface. This section provides information on each interface. Generally, hosts abandon data transfer to peripherals when a peripheral is BUSY continuously for dozens of seconds. To prevent this kind of time-out, the printer receives data very slowly, several bytes par minute, even the printer is in a busy state. This slowdown starts when the remainder of input buffer drops under several hundreds of bytes. Finally, the printer is BUSY continuously when the input buffer is full. The EPSON Stylus COLOR 3000 has three types of interfaces: Parallel, Serial, and optional Type-B. Each interface can be selected manually or automatically. Both modes are selected thorough the default setting mode.
