When the rear paper stacker is folded down, paper exits through
the rear of the printer and is stacked face up. The rear stacker is
mainly used for heavy print media. When used in conjunction
with the Multi Purpose Tray, the paper path through the printer
is essentially straight. This avoids bending the paper around
curves in the paper path inside the printer and enables feeding of
up to 203g/m² media.

LED
DISPLAYS
General
Printer status (as indicated by the LEDs) can be broadly
categorised as follows:
1.Normal status (Green): the printer is operating normally
e.g. it is ON LINE or processing.
2.Warning status (Amber): you can continue to use the
printer without intervention but an error may result.
3.Error status (Amber, blinking): you cannot continue to use
the printer. Intervention is required to recover from the
error. Fatal errors are irrecoverable and require a service
call.
When several different status situations occur concurrently, only
the status with the highest priority is displayed on the LEDs.
Warning status combined with the highest-priority normal status
is displayed on the LEDs.

required.
The Status Monitor in Windows provides a readable description of
the printer status corresponding to the indications of the LEDs. In
Mac, the printer driver provides status information once you have
sent a document to print. In Windows, if you have the Status
Monitor Preferences set to Pop up on alerts, this readable
message will be presented on screen whenever an abnormal
condition occurs. See “Using the printer software” on page 83 for
more information.

APER RECOMMENDATIONS
Your printer will handle a variety of print media, including a range
of paper weights and sizes, including envelopes. This section
provides general advice on choice of media, and explains how to
use each type.
The best performance will be obtained when using standard
75~90g/m² paper designed for use in copiers and laser printers.
Suitable types are:
• Arjo Wiggins Conqueror Colour Solutions 90g/m²;
• Colour Copy by Neusiedler.
Use of heavily embossed or very rough textured paper is not
recommended.
Pre-printed stationery can be used, but the ink must not offset
when exposed to the high fuser temperatures used in the printing
process.
Envelopes shoul d b e free f r o m twi s t , curl o r o ther d e f o rmati o n s.
They should also be of the rectangular flap type, with glue that
remains intact when subjected to hot roll pressure fusing used in
this type of printer. Window envelopes are not suitable.
Labels should also be of the type recommended for use in
copiers and laser printers, in which the base carrier page is
entirely covered by labels. Other types of label stock may
damage the printer due to the labels peeling off during the
printing process. Suitable types are:
• Avery White Laser Label types 7162, 7664, 7666 (A4),
or 5161 (Letter);
• Kokuyo A693X series (A4) or A650 (B5).

The Cassette Tray can handle paper in weights of 64g/m² to
120g/m². The Cassette Tray is ideal for printing A4 documents of
more than 1 page in length.
M
ULTI PURPOSE TRAY
The Multi Purpose Tray can handle the same sizes as the Cassette
Tray but in weights up to 203g/m². For very heavy paper stock,
always use the face up (rear) paper stacker. This ensures that the
paper path through the printer is almost straight.
The Multi Purpose Tray can feed paper widths as small as 100mm
and lengths up to 1200mm (banner printing)*. For paper lengths
exceeding 356mm (Legal 14in.) use paper stock between
90g/m² and 128g/m² and the face up (rear) paper stacker.
When using the Multi Purpose Tray, feed each sheet of paper or
envelope one-by-one, rather than stacking them. This helps to
avoid paper jams.

F
ACE UP STACKER
The Face Up Stacker at the rear of the printer should be opened
and the paper support extended when required for use. In this
condition paper will exit via this path, regardless of driver
settings.
The Face Up Stacker can hold up to 10 sheets of 80g/m² standard
paper and can handle stocks up to 203g/m².
Always use the Face Up Stacker and the Multi Purpose Tray for
paper stocks heavier than 176g/m².

RINTING FROM
Your printer’s menus provide access to many options. See “Using
the printer software” on page 83 for more information.
The Windows printer driver also contains settings for many of
these items. Where items in the printer driver are the same as
those in the menus, and you print documents from Windows, the
settings in the Windows printer driver will override those items in
the menus.
The illustrations in this chapter show the C3400n printer in
Windows XP/2000. However, the options shown for the C3400n
are the same when using the C3300 model. Other Windows
versions may appear slightly different, but the principles are the
same.
P
RINTER DRIVER SETTINGS
A printer driver is a software program that controls a printer. The
printer driver feeds data about printing requirements for a
document to the printer.
You can make printer driver settings either from Windows
Printers window (called “Printers and Faxes” in Windows XP) or
from within a Windows application. The driver settings you make
from the Windows “Printing Preferences” dialog box are
essentially default settings and will be remembered from one
Windows session to the next. The driver settings you make from
within a Windows application, e.g. in the File -> Print dialog box
in Microsoft Word, are those required for a particular job and will
not be remembered the next time you open this application. In
both cases, you can save and name (on the Setup tab) specific
sets of driver settings which can be recalled for future use.

RINTING PREFERENCES IN WINDOWS APPLICATIONS
When you choose to print your document from a Windows
application program a Print dialog box appears. This dialog
usually specifies the name of the printer on which you will print
your document. Next to the printer name is a Properties button.
When you click Properties a new window opens which contains
a short list of the printer settings available in the driver, which
you can choose for this document. The settings available from
within your application are only those which you may want to
change for specific applications or documents. Settings you
change here will usually only last for as long as the particular
application program is running.

S
ETUP TAB
When you click the Properties button from your application’s
Print dialog, the driver window opens to allow you to specify your
printing preferences for the current document.
1.Paper size should be the same as the page size of your
document (unless you wish to scale the printout to fit
another size), and should also be the same as the size of
paper you will feed into the printer.
2.You can choose the source of the paper to feed, which
may be Tray 1 (the Cassette Tray) or the Multi Purpose
Tray. You can either select the tray from the dropdown list
or you can click on the appropriate part of the printer
graphic to select your preferred tray.
3.The setting for paper weight should match the type of
paper on which you intend to print.
4.Click on the Paper Feed Options button to modify your
document to fit to paper of a different size and to access
advanced Cassette Tray and Multi Purpose tray settings.
Printing from Windows> 28
5.A variety of document finishing options can be selected,
such as normal one page per sheet, or N-up (where N can
be a maximum of 16) for printing scaled down pages at
more than one page per sheet.
Select the Poster printing option to print large pages as
tiles spread over multiple sheets.
6.You can choose to print on one side of a sheet only or to
use 2-sided printing (duplex printing). Your printer allows
you to carry out manual duplex printing, meaning you
must pass the paper through the printer twice. For more
information, see “2-sided printing (Windows only)” on
page 66. The Duplex Help button also offers guidelines
on how to carry out manual duplex printing.
7.If you have changed some printing preferences before and
saved them as a set under a specific name, you can recall
them under driver settings. Saving driver settings means
that you can avoid having to set printing preferences
individually each time you need them.
