The Setup Guide will help you get your new printer set up and
running quickly. Here is how it is organised:
Setup shows you how to get the printer ready, connect it to
your computer, install the standard and optional paper
handling accessories, load different types of paper and run
a self test.
Operation describes how to run your printer using the
control panel and gives you some hints on what to do if you
are having problems.
If you want more details about working with software or advanced
topics like graphics, read Chapters 3 to 6. Use it to find out more
about particular commands or to explore your MICROLINEs
advanced capabilities.
In addition to this manual, make sure you have the following
items:
1. MICROLINE printer
2. Platen knobs (2) (fitted)
3. Power cord
4. Ribbon cartridge (black for ML393, colour for ML393C)
5. Paper support
*Paper and interface cable sold separately

Important Note
If you are like most printer users you probably will not need to
read this entire book. Rather, you will flip from section to section
as required to learn how to make your printer do what you want
it to do. The Setup Guide contains information on loading paper
and most of the mechanical aspects of running your printer. The
Reference Guide pertains more to controlling your printers
features, such as format and print settings, and the method of
doing so.
● Chapters 3 and 4, IBM and Epson control code references, give
you the command codes and descriptions of their functions.
● Chapters 5 and 6 explain the particulars of writing commands
for generating graphics and designing your own characters.
● The Appendices provide you with code reference tables and
interfacing information, as well as other tables and technical
references you may require.
Selecting Drivers
Printer drivers are usually written for a particular model of printer
and identified by the name of that printer. Although most packages
offer several selections, they cannot have drivers for every printer.
Therefore, you may have to choose a driver that was not specifically
written for the ML393 but is compatible or nearly so. Installing a
driver is normally a simple process of making a selection from a
menu. Look for one of the following printers on your softwares
printer driver selection. As you go further down each list, you will
have access to fewer ML393 features.

Preliminaries
Open the access cover and remove the shipping restraint. (Save the
shipping restraint with the packaging materials).
The platen knobs should already be fitted to each side of the
printer. However, if they are removed for any reason, the flat side
of the shaft should be lined up with the flat side of the knob.

Optional Font Cartridges
Insert cartridges with the label facing upwards; ensure that the
cartridge is firmly seated.
Important: Ensure that the printer is turned off before inserting or removing font
cartridges.

Connecting to Your Computer
Before you can use your printer, you need to attach it to your
computer using an interface cable.
Note: Interface cables are not supplied with the printer.
1. Make sure both your computer and your printer are switched
OFF.
2. Attach the power cord to the socket in the rear of the printer,
and plug it into an earthed power source.
Note: Do not use an unearthed adapter with your printer. The printer must be
connected to an earthed power supply.

Loosen the metal plate with a Phillips screwdriver and slide to
uncover the proper connector for the interface cable you are
using.

Inserting the Ribbon Cartridge
IMPORTANT
You have just bought the best printer, so be sure to use the only
ribbons recommended for it. Original OKI ribbons are the only
ones recommended. Ask for them by name.
Please remember that if you buy any other ribbon your warranty
may be invalidated.
Purchasing inferior ribbons really does not make sense. They do
not last as long. They are prone to shredding, which can cause
damage to your printhead. That is why any short term savings on
cheaper ribbons are quickly lost.
So do not waste your time and money. Insist on OKI consumables
for your OKI printer.
You can order them from your printer supplier.
1. Unpack the ribbon cartridge. Remove the shipping restraint
and push the idler roller lock to the right to free the idler roller.

2. Open the printer access cover.
3. Centre the printhead.
Note: The printhead can get very hot during extended periods of printing—be
sure to let it cool off before you touch it.
4. Place the ribbon into the printer so that the pins on the ribbon
cartridge fit into the notches in the side plates of the printer.
Push down so that the cartridge snaps into position.
Centre the printhead
5. Thread the ribbon around the posts on the printhead, making
sure that you follow the proper path (refer to the following
illustration).
Thread ribbon around posts as shown
6. Turn the take-up knob clockwise to take up any ribbon slack.

Adjusting the Printhead Gap
The blue head gap lever (located on the righthand side of the
printer, below the access cover) adjusts the printhead for printing
on different types of paper. The following are recommended
settings for commonly used papers. You may want to try varying
the settings to get the easiest feeding and best print quality for the
paper you are using.

papers that have problems wrapping around the platen, as well as
for normal continuous-form paper.

Installing the Optional Cut-Sheet Feeder
The CSF 3001 single-bin and CSF 3002 dual-bin Cut-Sheet Feeders
(CSF) are ideal for high volume printing using single sheet paper.
Paper can be fed automatically, controlled either by the control
panel or through your computer. The dual-bin allows you to
alternate between letterhead and plain stationery.
Since the two CSF are installed in the same way, we will illustrate
the procedure with the CSF 3001, noting any differences as they
appear.
