Setting Up the Printer

Choosing a Place for the Printer

When you select a location for your printer, keep the following in mind:

l Place the printer on a flat, stable surface. l Place the printer close enough to the computer for its cable to

reach.

l Leave adequate room around the printer to allow for easy

operation and maintenance.

l Use a grounded outlet; do not use an adapter plug.

The illustration below shows a good printer location.

Choosing a Place

for

the Printer

Note: If you plan to use a printer stand, make sure it meets the

following requirements:

The stand must support at least 35 lb or 16 kg (twice the weight of the printer).

l The stand must not tilt the printer more than 15 degrees from

horizontal. With a cut sheet feeder, the stand must keep the printer level.

l If the paper supply is below the printer stand, make sure that

the paper cannot catch on the underside of the stand or on the stand supports.

Make sure that the power cord and the interface cable do not interfere with paper feeding. If possible, secure them to a printer stand support.

WARNING:

Avoid locations that are subject to direct sunlight, excessive heat, moisture, or dust.

Avoid using electrical outlets that are controlled by wall switches or automatic timers. Accidental disruption of power can wipe out information both in your computer’s memory and in your printer’s memory.

l Avoid using outlets on the same circuit with large

motors or other appliances that might disturb the power supply.

l Keep the entire computer system away from potential

sources of interference such as loudspeakers or the base units of cordless telephones.

1-8 Setting Up the Printer

Assembling the Printer

To assemble the printer, you need only do the following:

Install the paper feed knob.

l Install the ribbon cartridge. l Attach the paper guide.

Installing the paper feed knob

The first step in setting up the printer is to install the paper feed knob. You use this knob to manually feed paper in the printer when the printer is turned off.

You’ll find the paper feed knob packed in an indentation in the white foam packing material.

Insert the knob into the hole on the printer’s side and rotate it until it slips onto the shaft.

Setting Up the Printer

Assembling the Printer

Remove the ribbon cartridge from its box and remove the plastic

wrapper. Turn the ribbon-tightening knob in the direction of the arrow.

This removes any excess slack in the ribbon and makes it easier to install.

electrical outlet and load a sheet of paper.

Connecting the Printer to Your Computer

If the self test printed correctly and your printouts looked like the ones shown, you are now ready to connect your printer to the computer.

Your printer has a built-in parallel interface. If you have a suitable shielded cable, you should be able to connect your printer immediately. If you are unsure whether your computer has a parallel interface, see your computer’s operating manual.

Printer Selection Menus

Most application programs let you specify the type of printer you are using so that the program can take full advantage of the printer’s features. Many of these programs provide an installation or setup section that presents a list of printers to choose from.

Choosing from a menu

Because the family of Epson printers shares a great many commands, you can use an application program even if it does not list your printer on its printer selection menu. Choose from the following list

(the printers are listed in the order of preference):

L-750 L-1000 LQ-850/950/1050 LQ-500 LQ-2550 LQ-2500 LQ-800/1000 LQ-1500

If none of these printers is listed, select the first one available on the following list.

EX FX LX RX

To use all the features of your printer, however, it is best to use a program with one of the LQ printers on its menu. If your program does not list these printers, contact the manufacturer to see if an update is available.
