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: l Indicator off l Indicator on l Flash 1 - slow blink - 1 long flash every 4 seconds l Flash 2 - blink - 1 flash per second l Flash 3 - rapid blink - 4 flashes per second.
Ready LED (green) l Indicator on - the printer is on-line and ready to receive data. l Indicator off - the printer is off-line and cannot receive data. The meaning of the indicator LEDs when they flash (x) is summarised as follows: Flash type Ready Manual feed Error Meaning LED LED LED (Green) (Amber) (Amber) Flash 1 – slow blink x x Flash 2 — blink x x x Flash 3 — rapid blink x x x x x x The printer is data processing when printing has been suspended.
l Resuming data processing. The secondary functions of the control button are activated after turning the printer off line, then pressing and holding the switch for at least two seconds before releasing. The secondary functions are as follows: l Printing the demo and menu pages. NOTE Demo and menu pages can also be printed using the printer Status Monitor. l Printing any data held in the buffer after printing has been cancelled.
STATUS MONITOR After installing the printer driver software onto your computer, the Status Monitor is then installed to indicate what is happening to the printer when it is being used. (See the chapter entitled “Printer Drivers”.) This Status Monitor is also used to control and change the various printer settings. Using the Printer Status Monitor Viewing the status of the printer, and viewing or changing the printer settings are carried out as follows: 1.
Printer Setup Tab Selecting this tab provides access to the Printer Menu button, which, when selected, enables configuration of the printer settings via a series of tabs described in outline below. At all stages, detailed online help is provided via the Help button. 1. Paper: Paper set paper size for standard tray, secondary tray, MPF and manual feed, tray sequence and default number of copies. 2. Layout: Layout set paper cassette size, printer emulation, lines per page and paper orientation. 3.
8. Maintenance 2: 2 adjust print and page positions, settings, language, power save setting enable/disable, and select to print an error report, set tray ID. 9. About: About about this printer. Preferences Tab Selecting this tab provides the means to choose the information displayed by the Status Monitor and how/when the Status Monitor appears. The default Alert view setting ensures that the Status Monitor pops up to inform you of a condition that requires your attention e.g. toner low.
MENU FUNCTIONS The printer menu settings made from the Status Monitor can be seen collectively on a printed Menu Map. (For details of how to print such a map, see the next section.) It should be noted that many of these settings can be, and often are, overridden by settings made in the 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.
B4350, B4350N, B4350NPS OPERATOR PANEL The B4350, B4350n, B4350nPS operator panel consists of a menu driven control panel, an LCD display and a LED indicator. PANEL ELEMENTS 1.

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: l Paper and envelopes should be stored flat and away from moisture, direct sunlight and heat sources.
TRANSPARENCIES AND ADHESIVE LABELS The manufacturer of this printer recommends the following guidelines when selecting transparencies and adhesive labels for use in your printer: l Always use manual feed. l Always use rear output. l Media must be designed for use in laser printers or photocopiers and must be able to withstand 200°C for 0.1 sec. l Do not use media designed for use in colour laser printers and photocopiers l Labels 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).
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.
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 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.
3. Start the Status Monitor. Monitor 4. Click on [Printer Setup] tab - [Printer Menu] button - [Paper tab] - [Manual Feed] button. Adjust the media type to Transparency and the paper size to the size of the transparency being used. 5. Click on the [Apply] button, [Close] button then [OK] button to set the printer for transparencies. NOTE Remember to reset the printer for normal paper after printing transparencies.
Paper feed selection The paper feed, paper size, paper weight and media type can be set manually on the printer using the control panel as follows. 1. Press the Online button to return the printer to offline status. 2. Press the Menu button repeatedly until PRINT MENU is displayed, then press the Select button. 3. Press the Item button until the required paper feed is displayed. 4. Press the Select button. A plus (+) appears next to the selected paper feed.
5. Press the Online button to return the printer to ONLINE status. 6. Select the correct paper settings in the printer driver before printing the file. Media type and weight Set media type and weight as follows: CAUTION! If media type or media weight are not correctly set, print quality deteriorates and the fuser roller may be damaged. 1. Press the Online button to return the printer to offline status. 2. Press the Menu button until MEDIA MENU is displayed, then press the Select button. 3.
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.
PRINTER DRIVERS This chapter describes how to install a printer driver on two types of operating system – Windows and Macintosh. The printer drivers are all contained on the printer driver CD-ROM (CD1). Please refer to the readme file on this CD for the latest information on printer driver installation.
WINDOWS OPERATING SYSTEMS 1. With Windows running, insert the printer driver CD-ROM (CD1) into your CD-ROM drive. 2. If the CD does not run automatically, use [Start]-[Run...] and enter E:\setup (where E is your CD-ROM drive) in the Open field. 3. Click on [OK]. 4. Click on [Driver Installation] then [Install Printer Driver] and follow the on-screen prompts to complete your printer driver installation. 5.
MACINTOSH OPERATING SYSTEMS Please refer to the readme file on CD1 for details on installing the appropriate Macintosh drivers. INSTALLED OPTIONS Ensure that any installed options are enabled in the printer driver.
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.
PCL emulation The tabs available are the Setup Tab, the Job Options Tab and the Image Tab. Setup tab. 1 2 3 4 5 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.
4. 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. 5. A single on-screen button restores the default settings. Job Options tab 4 5 1 6 2 7 3 8 1. The output resolution of the printed page can be set as follows. l The highest quality setting prints at 1200 x 600dpi. This option requires the most printer memory and takes the longest to print.
4. In Raster (bitmap) mode, processing of the page image is done in the computer leaving little processing for the printer to do, although the file size may be large. In Vector mode, file sizes may be smaller and so transmission over a network, for example, may be faster. These effects are more pronounced for graphics printing than for text printing. 5. You can set a degree of toner saving for particular print jobs. 6.
Image tab 1 2 3 4 5 1. Dithering produces an intermediate greyscale by adjusting the combination of dots used in printing. Selecting a setting determines the degree of detail with which a graphics image will be printed. Mesh determines that a screen of dots is used for dithering while Line Art determines that an array of lines is used for dithering. 2. Select dithering texture by setting the size of dots used in the halftone screen. 3.
PS emulation The tabs available are the Layout Tab, the Paper/Quality Tab and the Job Options Tab. Layout tab 1 2 3 4 1. Page orientation can be set to portrait (tall), landscape (wide) or landscape rotated by 180 degrees. 2. Printed page order can be set as front to back or back to front of the document. 3.

Job Options tab 3 4 1 5 6 2 7 1. The output resolution of the printed page can be set as follows. l The highest Fine setting prints at 1200 x 600dpi. This option requires the most printer memory and takes the longest to print. l The Normal setting prints at 600 x 600dpi and is adequate for all but the most discerning applications. l The Fast setting prints at 300 x 300dpi and is suitable for draft documents, where print quality is less critical. 2.
6. Using the Advanced button gives you access to the facility to set mirror image printing or negative image printing. 7. A single on-screen button restores the default settings. SETTING FROM WINDOWS CONTROL PANEL When you open the driver properties window directly from Windows, rather than from within an application program, a somewhat more extensive range of settings is provided.
2. This button opens the same windows as described earlier for items which can be set from within application programs. Changes you make here, however, will become the new default settings for all Windows applications. 3. This button prints a test page to ensure that your printer is working.

CONSUMABLES AND MAINTENANCE This section deals with the replacement of the toner cartridge and image drum and general maintenance. CONSUMABLE ORDER DETAILS * Item Life Order No. Toner Toner, high capacity, B4350, B4350n, B4350nPS Image drum 2,500 A4 @ 5% 6,000 A4 @ 5% 01103402 01101202 25,000 A4 pages* 42102802 typical for continuous printing Please always use genuine consumables.
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.
Switch off the printer and allow the fuser to cool for about 10 minutes before opening the top cover. 1. Press the top cover release button and open the printer’s top cover fully. WARNING! If the printer has been powered on, the fuser may be hot. This area is clearly labelled. Do not touch. 2. Pull the coloured lever on the right side of the toner cartridge towards the front of the printer to close the cartridge then remove the used toner cartridge. 3.
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.
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.
RESETTING THE DRUM COUNTER After replacing the image drum, reset the drum counter to keep a correct count of the number of pages printed on the image drum. B4250, B4250N 1. Start the Status Monitor for the printer. 2. Click on Printer Setup tab - Printer Menu button Maintenance 1 tab. 3. Click the [Reset] button next to Drum Counter, then click on the [OK] button to reset the drum counter. B4350, B4350N, B4350NPS 1. Press the Online button to return the printer to offline status. 2.
3. Open the manual feed tray and insert a sheet of A4 plain paper between the paper guides, then click the [OK] button. 4. The printer grips the paper and prints a cleaning page. 5. If subsequent printing appears faded or uneven, try replacing the toner cartridge. Using the Control button 1. Press the control button to take the printer off line. 2. Open the manual feed tray and insert a sheet of A4 plain paper between the paper guides. 3.
CLEANING THE LED ARRAY Clean the LED array whenever a new toner cartridge is installed or if there are faded vertical areas or light printing down a page. Wipe the LED array gently with the cleaning pad that came with the new toner cartridge or use an anti-static cleaning pad that is generally available for computer cleaning.
TROUBLESHOOTING STATUS AND ERROR MESSAGES Your printer has been designed to give you helpful status feedback not only during normal operation but also if a printing problem occurs so that you can take appropriate corrective action. B4250, B4250N Both status and error messages are displayed in your chosen language in the Status Monitor, error messages being accompanied by the appropriate flashing of the Error indicator.
PAPER JAMS Provided that you follow the recommendations in this guide on use of 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.
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.
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.
Symptom Problem Solution Vertical white streaking or faint areas on page. Toner is low and does not distribute properly, or the drum is worn out. LED array is dirty. Vertical black lines. Hardware problem. Fuzzy print. LED array is dirty. Distorted print. Paper path, lamp assembly, or fusing unit problem. Faded print. Toner cartridge is not correctly installed. Toner low. Smeared or blotched Dirty rollers; toner print. dropped inside printer or image drum problem.
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. Symptom Problem Solution Printing is garbled. Incorrect driver is installed. Much of the printing delays will be caused by your application.
HARDWARE PROBLEMS Symptom Problem Solution Graphic image prints partly on one page, partly on the next. When you try to print nothing happens, but printer indicates it is ready to receive data. Garbage prints. Insufficient printer memory for this image at this resolution. Configuration error. Change the resolution, reduce the image size, or install more memory in your printer. Check cable connection. If more than one printer is available, make sure your printer has been selected.
INSTALLING OPTIONS The following options are available to extend the performance of your printer: l 10/100 BASE-TX Network Interface Card: to make the B4250 and B4350 network compatible l 16, 32, 64, 128, 256MB RAM DIMM: to extend the main memory of your printer and speed up the processing of large files l RS232C Card: to provide serial interface capability for the B4250 and B4350 l Second paper tray: to increase your printer’s paper handling capacity by 500 sheets (80g/m²) l Multi-purpose tray: to
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.
