PRINTER PLACEMENT
Before you start setting upyour printer, make surethat you have a suitable
place on which to locate it. By “a suitable place”, we mean: .
A firm, level surfacewhich is fairly vibration-free
.
Away from excessive heat (such as direct sunlight,heaters, etc)
Away from excessive humidity
.
Away from excessive dust
.
A steady power supply that is not subject to power surges should be connected tothe printer. For example, do not connect itto the samecircuit as a large, noise-producing appliance such as a refrigerator or an air conditioner.
.
Make sure the line voltage is the voltage specified on the printer’s identification plate.
.
Installthe printer where there issufficient room for thefanfold paper stack and any paper being fed in or printed out.
.
If you are connecting your printer with a parallel interface, make sure that thecable iswithin 2m (6ft) ofthe printer. An RS-232 connection usingthe optional SPC-8K interface converter can be made over longer distances.

Installing the front cover

After you have installed the ribbon cartridge, re-install the front cover.
1. Insert the tabs into the slots on the printer case.
2. Swing down the rear of the front cover to close it.
Figure 2-9. Installingthe frontcover.

Connecting the interface cable

Connect the printer to your computer using a standard Centronics parallel interfacecable. On a PS/2 or PC/AT-type computer, this means that you use the25-pin D-typeconnector atthecomputerend, and the Amphenol-type 36­pinconnector attheprinter end. The configuration of the printer’s connector is given in Chapter 11 should you need a cable for connecting to another computer.
If you need to connect to a serial port, use the optional Serial-Parallel Corwerter, SPC-8K.
Follow the procedures below to connect the interface cable:
1. Turn off the power switch both the printer and the computer.
2. Connect the interface cable to the printer as shown in Figure 2 Make sure that you press the plug into the interface connector.

Configuring your software for the printer

Most application software programs let you specify the type of printer you areusing sothatthesoftware can take full advantage of theprinter’sfeatures. Many of these software packages provide an installation or setup program that presents a listof printers.
This printer is setup to emulate theEpson printer commands at the factory. Ifyou want to emulate the IBM printer commands, you can select it with the Electronic DIP Switch (EDS) mode.
Choose one of the following (in order of preference) according to your selected Emulation mode.
I IYI Standard (Epson)mode / IBMrnode I

Star LC24-20
2 Star LC24-200
Epson LQ-860
3 4 Epson LQ-850 5 Star LC24-10
IBM PS/1 printer Proprinter X24E Proprinter 24P
I
You can also select one of NEC 24-wire printers to print graphics in the Standard emulation mode.
Ifyoursoftwarepackage doesnotmention printersby name, but asksinstead what features your printer is capable of, the most common questions are: “Can your printer perform a backspace?” and “Can it do a hardware form feed?”. You should answer “Yes” to both these questions.
Make surethatthe Electronic DIP Switch (EDS) issetfor the correct printer emulation, and that you have also selected the appropriate character set. (Refer to Chapter 5 for detailed information on the EDS mode.)
Ifyouareindoubtaboutthe configurationof your application software, seek expert advice. Your software supplier will probably be your most qualified reference.

chapter 3
PAPER INSTALLATION AND USE
Thischapterdescribes instructionsfor printing suchasselectingpaper types, iidjustingthe printing gap, and installing paper.

SELECTION OF PAPER

Your printer accepts any of the following types of paper:
Single sheets (cut forms) and stationary
Use the friction feed or the optional Automatic Sheet Feeder.
Fanfold forms
Fanfold forms have holes along the sides and perforations between thesheets.They are also called sprocketforms, continuous forms, or
just plain “computer paper”.
Printingon or neartheperforations of continuous fanfold forms may reduce printingquality, misalign the fanfold forms, or cause a paper
jam.
Multi-part forms
Youcan usemulti-part forms that have up to three parts includingthe original. It isrecommended thatyou load multi-part forms usingthe bottom feed slot with the optional Pull Tractor Unit. Use pressure sensitive multi-part forms with both side edges glued and a difference in thickness of 0.05mm or less between the side edges.
Labels
When printing labels,always selectthe type mounted on a continu­ous backing sheet with sprocket holes for use with a tractor. Do not try to print labels as cut forms because labels on a shiny backing sheet almost always slip a little. Itisrecommended thatyou loadlabelsfrom the bottom feed slotwith the optional PullTractor Unit.
19
NOTES:
1.
Never feed labels backward. Labels can easily peel off the backing and get stuck
in the printer. To remove labelsfrom the paper path after you finish printing, first tear off the labels at a point before the paper slot.
2.Use labels only under normal operating conditions. The labels are especially sensitive to temperature and humidity.
3.Do not leave labels loaded inthe printer between jobs. They curl around the platen and may jam when you resume printing.
Figure 3-1 shows the recommended print area for each type of papers.

ADJUSTING THE PRINTING GAP

The distance between the print head and the platen can be adjusted to
accommodate different paper thicknesses. The adjustment lever is located at the left side of the printer. Pushing the adjustment lever towards the rear of theprinter narrows the gap; pulling ittowards the front of the printer widens the gap.
There are five positions, and you can feel the lever clicking into each position.The secondposition from the rear (marked with “*”)is the one most commonly used for single sheets of paper.
Try different positions until you get the best printing results. NOTE: Printing with an inappropriate gap may drastically shorten the life
of the print head.

This printer accepts fanfold forms up to 10”wide. This printer can feed fanfold forms either from the rear or from the bottom
of the printer, as shown in Figure 3-3,
Figure 3-3. Paper path for fanfold forms
This section will take you through the procedures for loading, parking and unparking fanfold forms from the rear of the printer.
If you want to feed paper from the bottom, you must use the optional Pull Tractor Unit, (Refer to Chapter 7.)
