TME Control Panel

Gem/d User’sManual

Let’s turn our attention to the buttons and status lamps on the

.	control panel. Figure l-4 shows what the buttons and lamps can

	do for you.
	The two buttons in front are used to advance paper through
	the printer, to the next line on which you want to print. L-F-
	advances the paper one line at a time, and F.F. moves the entire
	form (or page) forward.
	The Online button allows you to switch between being
	“online” (meaning hooked-up and in a data transfer mode) with
	your computer, and being “local:’ Local means that the printer is
	incommunicado - not in a communicating mode with your
	computer.
A PRIMER OF YOUR PRINTER’S BASIC COMPONENTS
	This section is provided for those of you who are new to computer
	printer technology, and for now only want to know the most basic
	information about how the Gemini works.

A PRIMER OF YOUR PRINTER’S BASIC COMPONENTS

Figure l-5 shows what is called an “exploded” view of

Gemini-lox’s major components, and Figure 1-6is an elementary

logic block diagram for both models. But, because the Gemini

printers are so well designed, it isn’t necessary to know detailed

information about how it works - just that it does.

Expressed simply, when you turn the power switch “on:’the

alternating current is converted into direct current for the power

unit. The direct current powers the motors and the print head, as

well as providing power to the control board. The control board

does just that: controls the printer by means of a maze of

transistors, resistors, diodes, capacitors, and integratedcircuits

(IC, for short).

The control board contains the ROMs and RAMS, as

explained in the Glossary at the back of this manual. For now, it

is enough to know that the control board is the “brains” of the

machine. In fact, your new printer is smart enough to realize when

it has finished printing a short line, and instead of the print head

making an unnecessary trip along the rest of the blank line, Gemini

moves the paper up automatically, so no time is wasted before the

next characters are printed. This is why Gemini is said to be logic-

seeking.
