COMMAND SUMMARY 114

Thisprinterhas afull complement of features, making itan excellent partner for apersonal
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:

●
●
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
thatquicklyexpand and eject the jnk.
Avacuum is then produced as the
bubble contracts after thepulseends.
This draws fresh ink into the nozzle.

He
~
[F1ps
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 thatthe inkjet printer can be used for amuch wider range of applications than
other printers.
Auto-capping system
This printer moves the carriage to thehome positionand automatically caps the print head
whenever theprinter isturned on and off, ormore than 5secondshave 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.
Italsohelpstoreduce ink spillageintheeventtheprinterisheld foranyreason inotherthan
the horizontal position or is shipped.
Easy maintenance
This printeruses areplaceable Ink Cartridge (SC-10) thatcontains both the print head and
ink,the onlymaintenance required isasimplecartridge replacement. You can always rely
on high-quality printouts without complicated maintenance.
f1Tp u a rCS
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.

F1Tp u e a o Nb p
Versatilepaper handling
Single sheets and envelopes (COM 10size) are all accepted, and you can use either roller
feed or flat feed.
You can also feed paper with optional Automatic Sheet Feeder.
F7Tpfwtw R fFf 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 thebuttonson the controlpanel. The five buttonscan operate in combinations to
perform asurprising variety of functions, including micro-alignment.

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 asuitable place on which to locate the printer. By “a suitable
place”, we mean:
.Afirm, 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
.Supply itwith “clean” electricity. Do notconnect itto the same circuit as alarge, noise-
prod’ucingappliance such as arefrigerator.
●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 becapped 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 aspecial 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. Aclear 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.
