Advanced tab
1. You can specify which times of day your printer will be available.
2. Indicates current priority, from 1 (lowest) to 99 (highest). Highest 
priority documents will print first.
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 choose larger spooling documents over 
shorter ones. Use this option if you want to maximize 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 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.

documents. This is particularly useful on a shared printer to help 
each user find their own documents in the output stack.

CONSUMABLES AND 
MAINTENANCE
This section deals with the replacement of the toner cartridge and image 
drum and general maintenance.
CONSUMABLE ORDER DETAILS
* typical for continuous printing
Please always use genuine Oki consumables. 
TONER CARTRIDGE LIFE
How long your toner cartridge lasts depends on the print coverage; the 
percentage of the page that prints black. A typical letter has 3% to 5% 
print coverage; graphics usually have higher coverage. Higher print 
density means toner is used up faster. At 5% print coverage, a standard 
toner cartridge will print an average of 2500 pages. Remember, this is 
only an average: actual results may vary.
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.Item Life Order No.

WHEN TO REPLACE THE TONER CARTRIDGE
B4100, B4250
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
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.
WA R N I N G
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
B4100, B4250
When the drum reaches 90% of its life, a CHANGE DRUM message is 
displayed in the printer Status Monitor. Also, the Error LED indicator 
slowly blinks when the image drum requires changing. Change the image 
drum when the print becomes faint or begins to deteriorate.
B4350, B4350n
When the drum reaches 90% of its life, a CHANGE DRUM message is 
displayed in the operator panel LCD. Change the image drum when the 
print becomes faint or begins to deteriorate.
REPLACING THE IMAGE DRUM
It is recommended that you change the toner cartridge and clean the LED 
array at the same time as you change the image drum.
CAUTION!
The green image drum surface at the base of the cartridge is very delicate 
and light sensitive. Do not touch it and do not expose it to normal room 
light for more than 5 minutes. If the drum unit needs to be out of the printer 
for longer than this, please wrap the cartridge inside a black plastic bag to 
keep it away from light. Never expose the drum to direct sunlight or very 
bright room lighting. Always hold the image drum unit by the ends or from 
the top.
