INTRODUCTION Congratulations on buying an Oki colour printer. Your new printer is designed with advanced features to give you clear, vibrant colour prints and crisp black and white pages at high speed on a range of print media for the office.
PRINTER OVERVIEW FRONT VIEW 1. Output stacker, face down. Standard printed copy delivery point. Holds up to 250 sheets at 80g/m². 2. Operator panel. Menu driven operator controls and LCD display panel. 3. Paper tray. Standard blank paper tray. Holds up to 300 sheets of 80g/m²...
When the rear paper stacker is folded down, paper exits through the rear of the printer and is stacked here face up. This is mainly used for heavy print media. When used in conjunction with the multipurpose feed tray, the paper path through the printer is essentially straight.
CHANGING THE DISPLAY LANGUAGE The language used by your printer for display messages and for report printing can be changed quickly and easily as follows: READY ATTENTION Press the + key repeatedly to access the System Configuration Menu. Press the ENTER key to enter the System Configuration Menu.
PAPER RECOMMENDATIONS Your printer will handle a variety of print media, including a range of paper weights and sizes, transparencies and 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...
10mm. Paper or transparencies should be loaded print side up and top edge into the printer. Do not use the duplex (two sided printing) function. Dimensions Weight (g/m²)
FACE DOWN STACKER The face down stacker on the top of the printer can hold up to 250 sheets of 80g/m² standard paper, and can handle paper stocks up to 176g/m². Pages printed in reading order (page 1 first) will be sorted in reading order (last page on top, facing down).
LOADING PAPER CASSETTE TRAYS Remove the paper tray from the printer. Fan the paper to be loaded at the edges (1) and in the middle (2) to ensure that all sheets are properly separated, then tap the edges of the stack on a flat surface to make it flush again (3).
Page 14
Load letter headed paper face down and top edge towards the front of the printer, as shown. Adjust the rear stopper (1) and paper guides (2) to the size of paper being used. To prevent paper jams: > Do not leave space between the paper and the guides and rear stopper.
Page 15
For face down printing, make sure the face up (rear) stacker (3) is closed (the paper exits from the top of the printer). Stacking capacity is approximately 250 sheets, depending on paper weight. For face up printing, make sure the face up (rear) stacker (3) is open and the paper support (4) is extended.
> Envelopes should be loaded face up with top edge to the left and short edge into the printer. Do not select duplex printing on envelopes. > Do not exceed the paper capacity of about 50 sheets or 10 envelopes.
Your printer’s operator panel menus 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 menus, and you print documents from Windows, the settings in the Windows printer driver will override those items in the operator panel menus.
For two sided printing, you can choose to flip the page by the long edge or the short edge. Of course, this requires that a duplex unit be installed in your printer. If you have changed some printing preferences before and saved them as a set, you can recall them to avoid having to set them individually each time you need them.
The output resolution of the printed page can be set as follows. > The highest quality setting prints at 600 x 1200dpi. This option requires the most printer memory and takes the longest to print. > The normal setting prints at 600 x 600dpi and is adequate for all but the most discerning applications.
COLOR TAB Control over the colour output of your printer may be performed automatically to using manual adjustment. The automatic setting will be appropriate in most cases. The other options in this window only become visible when you select a choice other than automatic.
Changes you make here, however, will become the new default settings for all Windows applications. This button prints a test page to ensure that your printer is working. PRINTER SETTINGS IN WINDOWS > 21...
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.

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.

COLOUR TAB Colour output can be adjusted automatically or manually. Automatic adjustment will give excellent results in the majority of instances. However, if fine adjustment is needed to brightness or saturation, select the Manual Colour option. You can choose from a range of colour matching options, depending on the image source for your document.
DEVICE OPTIONS TAB In this window you can select which optional upgrades are installed on your printer. This is covered in more detail in the section in this guide about installing upgrades. To select this tab: From the Printer Properties dialogue, select Printer Properties tab.
FACTORS THAT AFFECT THE APPEARANCE OF PRINTS If you wish to manually adjust the colour settings in your printer driver, please be aware that colour reproduction is a complex topic, and there are many factors to take into consideration. Some of the most important factors are listed below.
Page 31
Printer driver colour settings The driver settings for Manual colour can change the appearance of a print. There are several options available to help match the printed colours with those displayed on screen.
ACCESSING THE COLOUR MATCHING OPTIONS The Colour Matching options in the printer driver can be used to help match your printed colours to the ones displayed on your monitor or from some other source, such as a digital camera.
SETTING THE COLOUR MATCHING OPTIONS On the Colour tab select Manual for Colour Matching. Choose the Manual colour setting and select from the following options: Monitor (6500k) Perceptual Optimised for printing daylight photographs. Monitor (6500k) Vivid Optimised for printing bright colours. Good for office graphics.
The Colour Swatch function prints charts which contain a range of sample colours. Note that this is not the full range of colours that the printer can produce. Listed on each sample colour are the corresponding RGB (Red, Green, Blue) values. This can be used to pick specific colours in applications that allow you to choose your own RGB values.
Page 35
The RGB colour displayed on your monitor may not necessarily match what was printed on the colour swatch. If this is the case, it is probably due to the difference between how your monitor and printer reproduce colour. Here, it is unimportant since your primary objective is to print the required colour.
It should be noted that many of these settings can be, and often are, overridden by settings in the Windows printer drivers. However, several of the driver settings can be left at “Printer Setting,” which will then default to the settings entered in these printer menus.
Select Tray Sequences of Auto Tray Select and Auto Tray Switch If a document to be printed demands a paper size not installed in the selected tray, the printer can automatically feed from the multipurpose tray instead. If this function is not enabled, the printer will stop and request the correct size of paper to be loaded.
CUSTOM setting see X-DIMENSION and Y-DIMENSION later in this table. Selects the type of media loaded in this tray. This will help the printer to adjust its internal operating parameters, such as engine speed and fusing temperature, to better accommodate the media to be fed.
Page 39
For CUSTOM setting see X-DIMENSION and Y- DIMENSION later in this table. Selects the type of media to be fed from the multipurpose tray so that the printer can adjust its internal parameters to better accommodate the selected type of media.
