OPERATOR PANELS
This chapter describes the function of the operator panel on your
printer. It is useful to describe the Status Monitor software at this
point as it provides the B4250, B4250n status information and the
equivalent of the menu control panel on the B4350, B4350n,
B4350nPS. (See “Printer Drivers” for installation of the Status
Monitor.)

B4250, B4250N
OPERATOR PANEL
The B4250, B4250n operator panel consists of 4 indicating LEDs and
a control button. From left to right, the LEDs indicate Power On, Ready,
Manual feed and Error.
LED INDICATORS
The LED indicators show the status of the printer and have five
operating conditions as follows:
lIndicator off
lIndicator on
lFlash 1 - slow blink - 1 long flash every 4 seconds
lFlash 2 - blink - 1 flash per second
lFlash 3 - rapid blink - 4 flashes per second.
All four LED indicators come on momentarily when power is switched
on using the main power switch.

PAPER RECOMMENDATIONS
For guidance on the media you can use with your printer, which input
tray and which ejection method to use, see the section entitled “Paper
and tray information” in the “Specifications” chapter.
PAPER AND ENVELOPE TYPES
The manufacturer of this printer recommends the following guidelines
when selecting paper and envelopes for use in your printer:
lPaper and envelopes should be stored flat and away from
moisture, direct sunlight and heat sources.
lUse a smooth finished paper such as copier or laser type paper
with a Sheffield (smoothness) rating of 250 or less. If in doubt,
please ask your paper supplier.
lUse envelopes designed for use in laser type printers.
lThe use of heavily laid or textured paper will seriously impact
on the life of the image drum.
lDo not use very smooth, shiny/glossy paper.
lDo not use heavily embossed headed paper.
lAvoid printing on both sides and putting paper through the
printer twice.
lAvoid using paper with perforations, cut-outs and ragged
edges.
lDo not use envelopes with windows or metal clasps.
lDo not use envelopes with self sealing flaps.
lAvoid using damaged or curled envelopes.
PAPER RECOMMENDATIONS > 33
TRANSPARENCIES AND ADHESIVE LABELS
The manufacturer of this printer recommends the following guidelines
when selecting transparencies and adhesive labels for use in your
printer:
lAlways use manual feed.
lAlways use rear output.
lMedia must be designed for use in laser printers or
photocopiers and must be able to withstand 200°C for 0.1 sec.
lDo not use media designed for use in colour laser printers and
photocopiers
lLabels should cover entire carrier sheet.

INSTALLING PAPER
NOTE
If you are topping up the paper in a paper tray, it is recommended that
you remove the remaining paper from the tray first then add the new
paper stock followed by the paper you removed. This ensures that the
oldest paper is used first to help prevent paper jams.
1.Remove the paper tray from the bottom of the printer and
place plain paper in the tray, keeping the level of the paper in
the tray below the guide arrowheads shown on the paper
guides (1).
1
3
4
2
NOTE
Load letter headed paper face down and top edge towards the front of
the paper tray.
PAPER RECOMMENDATIONS > 35
2.Adjust the rear paper support (2) to the size of paper you are
using by gripping the lugs (3), tilting and sliding the support
forwards or backwards as necessary.
3.Adjust the paper guides (1). It is important to adjust the paper
guides correctly to ensure that the paper is not skewed in the
print process. Paper jams may occur if this operation is not
carried out correctly.
4.Replace the tray in the printer. The paper level indicator (4)
provides a visual indication of how much paper is left in the
tray.
NOTE
If you have the optional second paper tray (Tray 2) and you are printing
from the first (upper) tray (Tray 1), you can pull out the second (lower)
tray to reload it. However, if printing from the second (lower) tray, do not
pull out the first (upper) tray as this will result in a paper jam.
FACE UP AND FACE DOWN PRINTING
For face down printing, make sure the rear paper exit tray is closed
(the paper exits from the top of the printer). The paper exit bin on the
top of the printer stacks printed pages face down, capacity 150 sheets
of weight 80 g/m². Pages printed in reading order (page 1 first) will be
sorted in reading order (last page on top, facing down).
For face up printing, make sure the face up rear paper exit tray is open
and the paper guide is extended if required. In this condition, paper
will exit via this path, regardless of driver settings. Paper is stacked in
reverse order, capacity 50 sheets of weight 80 g/m².
Always use this tray and the manual feed tray for heavyweight stocks
to reduce the possibility of paper jams.

AUTOMATIC FEED SEQUENCE
With no optional feed trays installed, the Autotray function in the Print
Menu is set by default to OFF and the Traysequence function is set to
DOWN. Ensure that the Autotray function is set to ON (default) when
you have either or both optional feed trays installed. In this way, if a
tray runs out of paper, automatic feed will take place in the order
Tray 1, Tray 2 (if fitted), Multipurpose feed tray (if fitted), provided
that these trays are set up for identical media.

HEAVYWEIGHT PAPER OR CARDSTOCK
The normal paper path from a main paper tray to the top output stack
involves two complete U-turns. This may sometimes cause very
heavyweight paper or cardstock to jam or misfeed.
Use the manual feed (multi-purpose) tray to feed this type of paper
and the rear paper exit to collect printed output. This gives a nearly
straight paper path through the machine and may prove more reliable
in this type of application.
PAPER RECOMMENDATIONS > 38
PAPER FEED, SIZE AND MEDIA SETTING
The process used to fuse (fix) the printed image to the paper involves
a mixture of pressure and heat. Too much heat will cause lightweight
paper to crease or curl and corrugations in transparencies. Too little
heat will cause the image not to fuse fully into heavyweight paper.
NOTE
Although media properties can be set in the printer driver for particular
jobs, when filling a tray with media it is recommended that you manually
set the printer to match the media as described here.

INTERFACES
Your printer is equipped with a selection of data interfaces:
1.Parallel – For direct connection to a PC. This port requires a
bi-directional (IEEE 1384 compliant) parallel cable.
2.USB – For connection to a PC running Windows 98 or above
(not Windows 95 upgraded to Windows 98) or Macintosh. This
port requires a cable conforming to USB version 2.0 or above.
The operation of a printer is not assured if a USB compatible
device is connected concurrently with other USB-compatible
machines.
When connecting multiple printers of the same type, they
appear as *****, ***** (2), ***** (3), etc. These numbers
depend on the order of connecting or turning on each printer.
3.Serial – for direct connection to a device that uses serial
printing (available as an option).
4.Ethernet – For network cable connection. This port is standard
on the B4250n, B4350n and B4350nPS and optional on the

OPERATION
This chapter provides a broad outline of how to operate your printer
from either a Windows or a Macintosh environment. In the former,
while PCL emulation is available on all printer models, PS emulation
is standard only on the B4350nPS model and is optional on the
B4350 and B4350n models.
PRINTER SETTINGS IN WINDOWS
NOTE
The illustrations in this guide relate to Windows 2000 PCL and PS
emulations – other operating system windows may appear slightly
different but the principles are the same.
The operator panel controlled menus and Status Monitor controlled
menus (described in the chapter entitled “Operator panels”) provide
access to many options.
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
operator panel and Status Monitor menus, and you print documents
from Windows, the settings in the Windows printer driver will override
those settings in the operator panel and Status Monitor menus.
PRINTING PREFERENCES IN WINDOWS APPLICATIONS
When you choose to print your document from a Windows application
program a Print dialogue box appears. This dialogue 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.

3.Specifies that documents should be spooled (stored in a
special print file) before being printed. The document is then
printed in the background, allowing your application program
to become available more quickly. Options follow:
This specifies that printing should not start until the last page
has been spooled. If your application program needs a lot of
time for further computation in the middle of printing, causing
the print job to pause for more than a short period, the printer
could prematurely assume that the document has finished.
Selecting this option would prevent that situation, but printing
will be completed a little later, as the start is delayed.
This is the opposite choice to the one above. Printing starts as
soon as possible after the document begins spooling.
4.This specifies that the document should not be spooled, but
printed directly. Your application will not normally be ready for
further use until the print job is complete. This requires less
disk space on your computer, since there is no spool file.
5.Directs the spooler to check the document setup and match it
to the printer setup before sending the document to print. If a
mismatch is detected, the document is held in the print queue
and does not print until the printer setup is changed and the
document restarted from the print queue. Mismatched
documents in the queue will not prevent correctly matched
documents from printing.
6.Specifies that the spooler should favour documents which
have completed spooling when deciding which document to
print next, even if completed documents are lower priority
than documents which are still spooling. If no documents have
completed spooling, the spooler will favour larger spooling
documents over shorter ones. Use this option if you want to
maximise printer efficiency. When this option is disabled the
spooler chooses documents based only on their priority
settings.
7.Specifies that the spooler should not delete documents after
they are completed. This allows documents to be re submitted
to the printer from the spooler instead of printing again from
OPERATION > 58
the application program. If you use this option frequently it
will require large amounts of disk space on your computer.
8.Specifies whether advanced features, such as pages per
sheet, are available, depending on your printer. For normal
printing keep this option enabled. If compatibility problems
occur you can disable the feature. However, these advanced
options may then not be available, even though the hardware
might support them.
9.This button provides access to the same setup windows as
when printing from applications. Changes made via the
Windows Control Panel become the Windows default settings.

between documents. This is particularly useful on a shared

TONER CARTRIDGE LIFE
How long your toner cartridge lasts depends on the print density; the
percentage of the page that prints black. A typical letter has 3% to 5%
print density; graphics usually have higher density. Higher print
density means toner is used up faster. At 5% print density, a standard
toner cartridge will print an average of 2500 pages. Remember, this is
only an average: actual results may vary.
6,000 A4 @ 5%01101202
The first toner cartridge installed in a new printer has to fill the image
drum reservoir and saturate the developing roller with toner. The first
standard toner cartridge normally produces about 1,000 pages after
installation.
CONSUMABLES AND MAINTENANCE > 63
WHEN TO REPLACE THE TONER CARTRIDGE
B4250, B4250N
Replace the toner cartridge after Toner Low displays in the printer
Status Monitor. Also, the Error LED indicator slowly blinks when toner
is low. After Toner Low displays, the printer will print about 100 more
pages then display Toner Empty and stop printing. Printing will
resume after a new toner cartridge has been installed.
B4350, B4350N, B4350NPS
When the toner is running low, TONER LOW is displayed in the
operator panel LCD. If printing continues without replacing the toner
cartridge, CHANGE TONER is displayed and printing is cancelled.
Printing will resume after a new toner cartridge has been installed.
REPLACING THE TONER CARTRIDGE
It is recommended that you clean the LED array at the same time as
you change the toner cartridge.
The toner used in this printer is a very fine dry powder contained in the
toner cartridge.
Have a sheet of paper handy so that you have somewhere to place the
used cartridge while you install the new one.
Dispose of the old cartridge responsibly, inside the pack that the new
one came in. Follow any regulations, recommendations, etc., which
may be in force concerning waste recycling.
If you do spill any toner powder, lightly brush it off. If this is not
enough, use a cool, damp cloth to remove any residue. Do not use hot
water, and never use solvents of any kind. They will make stains
permanent.
WARNING!
If you inhale any toner or get it in your eyes, drink a little water or
bathe your eyes liberally in cold water. Seek medical attention
immediately.

IMAGE DRUM LIFE
The life of an image drum depends on a number of factors, including
temperature and humidity, the type of paper used, and the number of
pages per job.
The image drum should last approximately 25,000 pages continuous
printing. This number is approximate because different numbers of
pages are printed each time and the environmental conditions and
the paper type used may vary.
WHEN TO REPLACE THE IMAGE DRUM
B4250, B4250N
When the drum reaches 90% of its life, a CHANGE DRUM message is
displayed in the printer Status Monitor. Also, the Error LED indicator
blinks fast when the image drum requires changing. Change the
image drum when the print becomes faint or begins to deteriorate.

print media, and you keep the media in good condition prior to use,
your printer should give years of reliable service. However, paper
jams occasionally do occur, and this section explains how to clear
them quickly and simply.
Jams can occur due to paper misfeeding from a paper tray or at any
point on the paper path through the printer. When a jam occurs, the
printer immediately stops, and the operator panel informs you of the
event. If printing multiple pages (or copies), do not assume that
having cleared an obvious sheet that others will not also be stopped
somewhere along the path. These must also be removed in order to
clear the jam fully and restore normal operation.
The printer may experience a paper jam in one of three areas.
lINPUT JAM - paper has failed to leave the selected feed tray
and enter the internal paper path of the printer. A typical
message indicates a paper jam and identifies the tray to
check.
lFEED JAM - paper has entered the printer but failed to reach the
exit. A typical message indicates a paper jam and advises you
to open the top cover for access.
lEXIT JAM - paper has reached the exit but has failed to exit
completely from the printer. A typical message indicates an
exit jam and advises you to open the top cover for access.

INPUT JAM
1.Remove the paper tray from the printer.
2.Remove any crumpled or folded paper.
3.Remove any paper from the underside of the printer.
4.Replace the paper tray.
After successful removal of any damaged or misfed paper, the printer
should continue printing.
FEED JAM OR EXIT JAM
1.Remove the tray and clear any misfed sheets as given above.
2.Open the top cover.
WARNING!
The fuser area will be hot. This area is clearly marked. Do not touch it.
CAUTION!
Never expose the image drum unit to light for more than 5 minutes.
Never expose the image drum unit to direct sunlight. Always hold the
image drum unit by the ends or from the top. Never touch the surface of
the green drum inside the image drum unit.
3.Carefully lift out the image drum, complete with the toner
cartridge. Be careful not to touch or scratch the green drum
surface.
4.Remove any jammed sheets from the paper path.
5.Re-install the image drum complete with toner cartridge,
ensuring that it correctly locates into the slots on each side of
the printer.
6.Close the top cover and press down to latch it closed.
TROUBLESHOOTING > 73
7.The printer will warm up and commence printing when ready.
The page lost through the jam will normally be reprinted.
NOTE
If the edge of the jammed paper protrudes (or can be seen) from the exit,
reinstall the image drum, close the top cover and switch the printer on.
Remove the jammed paper from the exit when the exit roller begins
rotating after a few seconds after switching on. However, if the jammed
paper cannot be removed, contact a service representative.

SOFTWARE PROBLEMS
Your software (operating environment, applications and printer
drivers) controls the printing process. Make sure you have selected
the right driver for use with your printer. See your software
documentation for more information.
SymptomProblemSolution
Printing is garbled.Incorrect driver is
installed.
Printer’s output is
below rated speed.
Size of top margin
increases with each
page printed.
Much of the printing
delays will be caused by
your application.
Sometimes purely text
documents will print
slowly depending on
the selected fonts and
how they are
transferred to the
printer.
Creeping text. Number
of lines per page in
software is not equal to
number of lines per
page of printer.
Install an appropriate driver.
For maximum speed, use text in your
document and use a printer resident font.
Many software packages assume 66 lines
per page, but your printer’s default is 64.
Adjust software accordingly, or set LINES
Per PAGE in the soft control panel to
equal lines per page in your software.

INSTALLING OPTIONS
The following options are available to extend the performance of your
printer:
l10/100 BASE-TX Network Interface Card: to make the B4250
and B4350 network compatible
l16, 32, 64, 128, 256MB RAM DIMM: to extend the main
memory of your printer and speed up the processing of large
files
lRS232C Card: to provide serial interface capability for the
B4250 and B4350
lSecond paper tray: to increase your printer’s paper handling
capacity by 500 sheets (80g/m²)
lMulti-purpose tray: to extend the range of media your printer
can accommodate (capacity 100 sheets (80g/m²) or 50
envelopes)
lOne of the following can be added:
(a)8MB Flash DIMM: to allow the storage of additional
fonts or bar codes for the B4250, B4250n, B4350,
B4350n
(b)16MB Flash DIMM: to allow the storage of additional
fonts or bar codes for the B4250, B4250n, B4350,
B4350n
(c)PostScript PS level 3 DIMM: to add PostScript emulation
to the B4350 or B4350n. Cannot be added in
conjunction with extra flash memory.
The B4350 PS option is supplied as 2 DIMMs: a PS DIMM
and a 16MB RAM DIMM. When fitted into a basic B4350
or B4350n (i.e. one with no memory upgrade already
fitted) the PS DIMM will expand into the 16MB RAM
DIMM in order to work, and the amount of memory
available for general operation of the printer will
therefore not change. It will remain at 16MB, which is
the printer's base memory.
INSTALLING OPTIONS > 78
If you require to install a PS upgrade into a B4350 or
B4350n which already has a memory upgrade installed,
discard the 16MB RAM DIMM which ships with the PS
option and install only the PS DIMM. The result will be
that the amount of overall memory available to the
printer will decrease by 16MB as the PS code expands
into 16MB of RAM currently installed. For example, a
user who already has 128MB installed (total memory is
therefore 128+16=144MB) will fit only the PS DIMM and
will then have 128MB of RAM left for printing.
INSTALLATION PROCEDURE
To install any of the above options, follow the detailed installation
sheet that accompanies the option.
