COMMAND SUMMARY

114

Thisprinter has afull complement of features, making it an excellent partner for a personal
computer. It supports the Epson/IBM printer commands and character sets, enabling it to
printjust about anything your computer can generate, both text and graphics.

FEATURES OF THE PRINTER

Some of main features are the following:

●

●

b

●

●

●

●

Ink jet printing system
Auto-capping system
Easy maintenance
2-way power supply
Versatile paper handling
Extensive software support
Easy operation

Inkjet printing system

The inkjet printing system prints characters and graphics by firing ink drops at the paper
from thin nozzles.

Heating the ink in these nozzles, by
applying electrical pulses to the
heating elements, produces bubbles
thatquickly expand and eject the jnk.

A vacuum is then produced as the
bubble contracts after the pulseends.
This draws fresh ink into the nozzle.

B

H e

~

[

F 1 p s

An important feature of this printing system is the simple construction of individual
nozzles.
This construction has the following advantages in addition to reducing manufacturing
costs.

Chapterl INTRODUCTION 1

. The printing mechanism is more durable and smaller.
. Print quality is higher because of greater nozzle density.

● Quiet, non-impact operation.

This means that the inkjet printer can be used for a much wider range of applications than
other printers.

Auto-capping system

This printer moves the carriage to the home position and automatically caps the print head

whenever theprinter isturned on and off, or more than 5 secondshave passed sincethe last
data was received.

This auto-capping system prevents the head from drying out or becoming clogged with
dust, and ink dropping or evaporation.
Italsohelpsto reduce inkspillagein theeventthe printerisheld forany reason inother than

the horizontal position or is shipped.

Easy maintenance

This printer uses a replaceable Ink Cartridge (SC-10) that contains both the print head and
ink,the only maintenance required is a simplecartridge replacement. You can always rely
on high-quality printouts without complicated maintenance.

f 1 T p u a r C S

Z-way power supply

You can use this printer with the AC power source using the AC adapter, or without AC
power source using the optional NiCd battery pack, BP-10.
With the optional battery pack, your printer can even be used outdoors. Great for laptop
computer users.

F 1 T p u e a o N b p

Versatilepaper handling

Single sheets and envelopes (COM 10 size) are all accepted, and you can use either roller
feed or flat feed.
You can also feed paper with optional Automatic Sheet Feeder.

F 7 T p f w t w R f F f f

Extensive software support

Since it is compatible with the Epson and IBM printers, it works with any software that
supports those printers. That includes most word-processing and graphics programs,
spread-sheets, and integrated software packages.

Easy operation

Indicator displays and beep tones provide immediate, easy to understand feedback when
you press thebuttons on the control panel. The five buttons can operate in combinations to
perform a surprising variety of functions, including micro-alignment.

Chapterl INTRODUCTION 5

REQUIREMENTS

Before you start unpacking and setting up your printer, make sure that the following
requirements are satisfied.

Location of the printer

Make sure that you have a suitable place on which to locate the printer. By “a suitable

place”, we mean:

. A firm, level surface which is fairly vibration-free
. Away from excessive heat (such as direct sunlight, heaters, etc)
. Away from excessive humidity or dust
. Use the printer where there is sufficientroom for the paper and any paper being fed in

or printed out.

. Make sure that the interface cable is within 2m (6ft) of the printer.

● Do not place objects on top of the printer.

Requirements of the power supply

. Supplyit with “clean” electricity. Do notconnect it to the same circuit as a large, noise-

prod’ucingappliance such as a refrigerator.

● Make sure the line voltage is the voltage specified on the AC adapter’s identification

plate.

. Do not unplug the AC adapter cable to turn printer off. The print head will be damaged

because itcannot be capped correctly. If theAC adapter cable isunplugged by mistake,
plug it in again and switch the printer on and off to cap correctly.

Requirements of the Ink Cartridge

. Do not remove the Ink Cartridge from the printer unless it has to be replaced.
. Do not touch the print head of the Ink Cartridge. The print head is a special precision

component.

● Do not subject the Ink Cartridge to physical shock or vibration. Ink may be spilled on

your hands or clothes.

● Do not attempt to refill the Ink Cartridges. A clear printout camot be obtained.

. Do not disassemble the Ink Cartridge. Ink may be spilled on your hands or clothes.
. Do not place the head of the Ink Cartridge face down.

● Connecting the power supply

. Installing the Ink Cartridge
. Comecting the printer to your computer

UNPACKINGAND INSPECTION

Now unpack the contents of the shipping carton, and check each item in the box against

Figure 2-1 to make sure that you have everything (there should be four items).
If any of these items are missing, contact your supplier.

ONLINE button

The ONLINE button setsthe printeron-line andoff-line. The statuschanges each time you
press the button.

When the printer is on-line, it can receive and print data from the computer. When the
printer isoff-line, itstops printingand sends thecomputer a signal indicating that itcannot
accept data.

Chapter4 CONTROL PANEL OPERATIONS 19

The printer powers up in the on-line status if paper is loaded. If paper is not loaded, the
printerpowers up off-line with the indicator illuminating and the indicator
blinking.When you load paper, you must press the [

ON

[ button to set the printer

on-line.
You will want to press the I ONLINE ]button:
. Before and after any other panel operation

The otherpanel buttonsoperatein theoff-line state. Press the I ONl-lNE ~buttonto go

go back on-line.

. To pause during printing

Ifyou press the I ON

I button during printing,the printer stopsprinting and goes

off-line, allowing you to check the printout or change a control panel setting. Printing
resumes when you press the I

ON

Ibutton again to go back on-line.

LINE FEED button

If you press this button while off-line, the paper will feed forward. If you hold the button
down, the printer will perform consecutive line feeds.

If you also press the I ON

] button while you are line-feeding, the paper will eject

automatically the current page. This is explained later.

FWDADJ button

For fine alignment, you can feed the paper forward in very small increments as follows:

1. Press the ~ ON button to set the printer off-line.

2. press andholddownthe ~ button.Thepaperwill start advancing inaseries
of small steps. When you want to stop, release this button.

REVADJ button

You can also feed the paper in small increments in reverse, to return to a higher position
on the same page.

1. Press the I

ON button to set the printer off-line.

2. Press and hold down the I

] button. The paper will start moving backwards

in a series of small steps. When you want to stop, release this button.

If you press this button while on-line, this will change the Print Quality between High
Quality (HQ) and Economy. You will hear one beep tone when the Economy mode is

selected, and twice when the HQ mode is selected.The print speed isthe same in both the
Economy and HQ mode, but the Economy mode uses less ink.
When you select the Economy mode with this button, the printer ignores the Print Quality
commands from the computer, and prints all text and graphics with the Economy mode.

PITCH button

This button allows you to selectthe printing pitch. Remember that the printer must be off-

line for you to do this. Successive presses of this button will select the following options

in order (Note that semi-condensed pitch is not available in the IBM mode):

Pitch
Pica (1OCPI)

Elite (12CPI)
Semi-condensed (15CPI)
Condensed pica (17CPI)

If you press this button while on-line, this will change the Font style.

You willhear onebeep tone when theH-Gothic font is selected, and twice when theRoman

than it has actually printed, and this unprinted data must be cleared out before restarting.
Turning power off is one way to clear the buffer, but there is another way:

4. Release these buttons, make any necessary control panel settings, then set the printer
back on-line.

It is essential to halt the printing program on the computer before you do this panel
operation.
Otherwise, when you go back on-line the computer will start sending data again and the

printer will continue printing, with missing data where the buffer was cleared.
