Genicom Nov 00 4 GENICOM LN28 and microLaser 280 User Guide About the Printer About the Printer The GENICOM LN28 and microLaser 280 printer uses a data modulated laser beam and conven- tional dry-ink xerographic processes to produce images up to 1200dpi resolution at a paper output speed of 28 pages per minute. The printer can accommodate both plain paper and other print media, and feeds paper from either a main 500-sheet paper tray or from the front tray, which is designed to feed special print media such as labels and transparencies. There are four paper handling options available for the printer, including a Duplexer for two-sided printing, a 500-Sheet Feeder for additional paper capacity or variety, a High Capacity Feeder for even greater paper feeding options, and an Offset Output Tray to hold and separate large print jobs. There are also four replaceable components: the Toner Cartridge, the Fuser, the Transfer Roller, and the High Capacity Feeder Feed Rolls. You may connect the printer to either a local computer or a computer network system. Application and print driver software on the computer controls image generation and print processing. The computer sends the electronic image to the printer, where the printer turns the electronic image into a black and white printed image. Features Your laser printer has the following features: • Quality printing at a high speed The printer has an output of 28 pages per minute with a resolution up to 1200 dpi. • Flexible use of paper sources and delivery methods The base configuration of the printer includes one 500-sheet universal paper feeder and a front tray.

USB Port The USB port of your printer provides a reliable, high-speed, bi-directional connection between your printer and PC, The USB standard is designed to deliver complex, graphic-rich documents to the printer with speed and accuracy. USB-enabled printers and PCs allow up to 127 devices to be attached to a single USB port. Fast 12Mbps communication from your PC and printer with abso- lute reliability. OS Support The USB port of your printer supports the following operating system environments: • Microsoft Windows 95b and 95c (also known as OSR 2.0, OSR 2.1 and OSR 2.5) If you are using one of these operating systems, your PC may require an optional upgrade to work properly with USB. This upgrade is called USBSUPP.EXE and is provided in the \OTHER\USB directory of your Windows 95 CD-ROM. GENICOM does not supply this update. To find out if your hardware/operating system combination supports USB, run the free program USBREADY.EXE, available from www.usb.org. • Microsoft Windows 98 and 98se These operating systems come with complete support for USB. You should still run USBREADY.EXE from www.usb.org to ensure that the required software and hardware are installed. • Apple Mac OS 8.6 and above This version of Apple's operating system ships with the USB equipped systems and contains the necessary code to support USB. No additional software or hardware should be required. Hardware Support The USB port of your printer supports the following hardware: • Intel

Genicom Nov 00 2-6 GENICOM LN28 and microLaser 280 User Guide Connecting the Printer to the Host Computer Most recent Intel systems will contain the needed components. However, there are a number of older systems that, while having USB hardware, have an obsolete USB implementation . Your GENICOM USB printer will not work with these older systems unless a separate USB controller card is installed in your system. It is possible to have working hardware but not have a physical port, in which case the proper connector must be purchased from the system supplier. NOTE: Systems made in 1996 and earlier probably do not support USB correctly on the motherboard; systems made in 1997 may or may not properly support USB; and systems made since 1998 probably do support USB correctly. • Apple The Apple iMac and G3/G4 systems come with working USB hardware and fully support your GENICOM USB printer. Older PCI-based Macintosh systems may be upgraded with a USB card. This configuration should work with the correct version of the operating system. Installation for Windows Use the following procedure to install USB for Windows: 1. Verify that your system supports USB and has an available USB connector. If you do not have an available connector, you may need to purchase a USB hub. NOTE: You may use an unpowered USB hub, since the printer is considered a self-powered device and will not draw power from the USB port. 2. Power on the host system and the printer and allow the two systems to finish booting. 3. Attach the USB cable to both the printer and the host. It does not matter which host connec- tor you attach the cable to; however, make sure you always attach it to the same connector. NOTE: The USB printer port created is associated with the actual port to which the device is attached. If the printer is attached to a different hardware port, a new USB printer port will be created, even though it is attached to the same printer. The maximum length of a USB cable is 16 feet (5 meters). Longer distances may be spanned if intervening hubs are used. There is a limit of 5 hubs between the host and any given device, giving a maximum distance of 98 feet (30 meters). 4. Windows displays a dialog box stating that new hardware has been found and Windows is searching for a driver. 5. Browse to the location of the USB port software and select the appropriate version for either Windows 95 or Windows 98 (\Software\USB\Win95 or \Software\USB\Win98 on your CD-ROM or the location where you expanded the driver files). 6. Windows creates a GNUSBn printer port. 7. At this point, you may install the printer normally, either by using the "Add Printer" wizard or by running the appropriate setup program, or your system may announce that "New Hardware has been found". In either case, install the driver required for your printer at this time. 8. After the printer has been installed, make sure that it prints to the GNUSBn port.

GENICOM LN28 and microLaser 280 User Guide 2-7 Connecting the Printer to the Host Computer 9. Ensure that the Spooler settings for the printer have "Disable bi-directional support for this printer" checked. 10. Your GENICOM USB printer is now ready to print. Installation for Mac OS 8.6 1. Power on the printer and the host computer. 2. Ensure that the "Apple LaserWriter Software" is installed. 3. Attach the USB cable to the host and the printer. Note that the printer is considered a "self powered" device and as such may be plugged into any available USB port on the Macintosh, including the one on the keyboard . NOTE: The keyboard USB port on an iMac can only source a minimal amount of power. Plugging a bus-powered device into this port can cause problems because of insufficient power. Since the GENICOM USB Printer draws no power from the bus, it should be possible to use this port without affecting other USB devices. 4. Open the "Desktop Printer Utility" (installed when you installed the Apple Laser Writer Soft- ware). 5. Choose the correct driver to use, depending on the printer you are installing. 6. Choose "Printer (USB)" and press "OK". 7. Choose the PPD file that corresponds to your printer. 8. Choose the correct printer. 9. Press "Create". 10. You now have a desktop shortcut to the GENICOM USB printer and are ready to print.

Genicom Nov 00 4-2 GENICOM LN28 and microLaser 280 User Guide Upgrading Printer Firmware About this Chapter This chapter provides information about maintaining your printer. Although the printer requires very little maintenance, with normal daily use you will need to perform some routine maintenance procedures, including replacing consumable items and cleaning the printer. This chapter also con- tains information about moving and storing the printer. Upgrading Printer Firmware The executable firmware for the printer controller is stored in FLASH memory. You can easily upgrade this firmware on site when a new version of code is available. The upgrade process involves sending the new code, which is usually named with a .LOD extension, to the printer using either the parallel or network interface. When the printer receives the file, it will automatically recognize it as a firmware upgrade file and will program it into the FLASH memory. During this process the printer will display information about each sub-file that it is receiving or programming. When fin- ished, the printer displays the text “Upgrade Completed” and reboots, executing the new firmware. Contact your dealer or service provider for more information about firmware upgrades. Upgrading Firmware Using the Parallel Interface To upgrade the printer using the parallel interface, go to the DOS prompt and use the copy com- mand to copy the new file to the printer. For example, type “copy newversion.lod/b lpt1” at the DOS prompt, where “newversion” is the name of the firmware upgrade file and “lpt1” is the printer you would like to upgrade. Be sure to use the “/b” switch on the copy command line to ensure that the data is sent in binary mode. NOTE: If you are using a PC that is not running Windows or if you do not have any printer drivers installed and configured to use the parallel interface, you will need to configure the parallel port for permanent retry by entering the following command PRIOR to entering the copy command discussed above: mode lpt1:,,p If you are running Windows, you may get an error message during the upgrade process that indicates that the printer is busy or that there is a printer error. This message box will contain check-boxes for “Retry” or “Cancel”. DO NOT SELECT CANCEL. This error message is only a result of the printer programming a large file into FLASH memory and will disappear once the programming is completed. Upgrading Firmware Using the Network Interface To upgrade printer firmware using the network interface, simply send the new file to the printer using whatever procedure you normally use to send a print file. This procedure varies depending on the network environment.

GENICOM LN28 and microLaser 280 User Guide 4-3 Replacing Printer Components Replacing Printer Components Replacing the Toner Cartridge The toner cartridge contains the dry ink as well as the xerographic drum and associated compo- nents that create the xerographic image on a sheet of paper. The toner cartridge will eventually run out of ink through normal use. When the toner is low, printed images will be uneven or very light. Use the following guidelines when using or storing a toner cartridge: • An unopened and correctly stored toner cartridge has a shelf life of approximately two years. • Do not open the box containing the toner cartridge until you are ready to install the cartridge into the printer. • Store the toner cartridge box horizontally—not on end. • Keep the cartridge out of the reach of children, and in an area where the temperature remains between 32°F and 95°F and the humidity remains between 15% to 85%. If you bring a cold toner cartridge into a warm room, wait a least an hour for the temperature to stabilize before opening the cartridge box. • Do not disassemble the toner cartridge. • Toner is a safe material, but if you get any on your hands DO NOT wash them in hot water. Use only cold water to wash off toner. Hot water sets the toner and makes it difficult to remove. • A shutter protects the photosensitive drum from ambient light. Do not open the drum shut- ter by hand. Use the following procedure to replace the toner cartridge: 1. Place a drop-cloth or some paper on the table or floor near the printer. Drum Shutter CAUTION: Do not expose the new toner cartridge to strong light for more than a few min- utes before installing it into the printer. WARNING! Do not dispose of used toner cartridges in an incinerator or in an open fire.

GENICOM LN28 and microLaser 280 User Guide 4-7 Replacing Printer Components Replacing the Fuser The fuser melts the toner image into the paper to form a finished print. The fuser wears with nor- mal use and can leave dirt or marks on printed sheets when worn. The normal life of a fuser is approximately 200,000 A4/Letter size prints at 5% area coverage. Running high image density prints or large format paper will cause the fuser life to be shorter. NOTE: In the following procedure, the left and right sides of the printer are those to the left and right of a person facing the rear of the printer. Use the following procedure to remove and replace the fuser: 1. Turn the printer off by pressing the [ O ] on the power switch on the right side of the printer, and disconnect the AC power cord from the wall outlet. Wait at least 30 minutes before pro- ceeding to remove the fuser.. NOTE: If the high capacity stacker is installed, it is not necessary to remove it to replace the fuser; however, removing the stacker will make it easier to access the fuser. WARNING! The fuser becomes very hot during operation. Do not touch the fuser until it is cool.

There are four basic types of printer problems: • Installation problems If there is a problem with the printer when you first turn in on, refer to “Installation Prob- lems” on page 5-2 for information about possible installation problems. • Paper Jams If there is a paper jam, refer to “Paper Jams” on page 5-4 for procedures to remove the jam. • Print quality problems If the finished prints delivered to the output tray display image problems such as image black spots or vertical lines on the page, refer to “Print Image Quality Problems” on page 5-27 and complete the procedure provided for the specific image problem that you have encountered. • Miscellaneous problems If you have a printer problem but the control panel does not display a warning message or error message, refer to “Miscellaneous Problems” on page 5-35 and follow the directions for correcting that problem. Many of these printer problems are indicated by a warning or error message appearing on the con- trol panel display. If the printer control panel displays a warning message or error message, refer to “Warning Messages and Error Messages” on page 5-39 and complete the actions prescribed for the specific warning or error message. Installation Problems It is common for simple oversights during printer installation to cause problems when you first turn the printer on, resulting in noise, smoke, or smell; an inoperative printer; or the absence of a ready message on the control panel.

GENICOM LN28 and microLaser 280 User Guide 5-3 Installation Problems Inoperative Printer If you have problems turning on the printer, check the possible causes listed in the table below. If the printer will not start after checking these items, turn the printer off, disconnect the power cord from the AC outlet, and contact your dealer or an authorized service provider. No Ready Message After warming up, the printer control panel displays the text “Ready”, indicating that the printer is ready to print. If the printer does not show this message, but shows an error message instead, refer to “Warning Messages and Error Messages” on page 5-39 to determine the appropriate action for the specific error message that is shown. If the printer does not display either the “Ready” message or an error message, contact your retailer or sales representative. Noise, Smoke, or Smell If you notice unusual noise, smoke, or smell after turning the printer on, turn the printer off imme- diately and disconnect it from the AC wall outlet. Use the following procedure to determine the cause of and alleviate the problem: Description Possible Cause Action There is no power. The power switch is not set to [ I ] (on). Check the power switch. See “Step 7: Connecting the Power Cord and Turning the Printer On” on page 2-15. of the Installation Guide. The power cord is not properly plugged into an AC outlet or into the AC connector on the rear of the printer. Set the power switch to [ O ] (off) and then connect the power cord firmly to the AC connector and to the AC outlet. See “Step 7: Connecting the Power Cord and Turning the Printer On” on page 2-15. of the Installation Guide. Voltage of the AC power is not correct. Verify that the AC outlet is rated for the voltage of your printer. See “Electrical Requirements” on page 2-5. of this guide. The fuse on the power cord is not functioning. (UK only) Verify that the fuse on the power cord is intact. (UK only) The AC wall outlet is not functioning. Verify that voltage is present at the AC wall outlet by connecting another electrical device to the outlet. If power does not flow to the other device, check the AC wall outlet circuit breakers for a tripped breaker. There is interference from other electrical devices on the same circuit. Unplug all electrical devices from the AC wall outlet circuit, and then reconnect only the printer. Turn printer power on. Thermal sensors may have shut down the printer. Turn the printer off and wait 20 minutes, then turn the printer back on. Power is frequently interrupted. The printer is malfunctioning. Turn the printer off and disconnect the power cord from the AC outlet. Contact your dealer or an authorized service provider.

Genicom Nov 00 5-4 GENICOM LN28 and microLaser 280 User Guide Paper Jams 1. Refer to the pictorial unpacking sheet and the Installation Guide included in the printer packaging and make sure you have removed all shipping spacers and protective tape from the inside of the printer, the paper trays, and the toner cartridge. 2. Open the covers on the printer and carefully inspect the fuser area. Remove any pieces of paper that may be stuck in the fuser. 3. Check the inside of the printer for any obviously broken or detached parts. If you find a bro- ken part, contact your retailer or sales representative. 4. Check the exterior of the printer for broken covers. If you find a broken cover, contact your retailer or sales representative. 5. Verify that the AC wall outlet is the correct voltage for your printer. 6. Remove any paper you have loaded in the main tray, check the inside of the tray well for stray sheets of paper, and reload the paper into the main tray. 7. Connect the printer to the AC wall outlet and turn the printer on by pressing the [ I ] on the power switch on the right side of the printer. 8. If this procedure does not eliminate the noise, smoke or smell, or if the problem returns, turn the printer off, unplug the AC power cord from the AC wall outlet, and contact your retailer or sales representative. Paper Jams Paper jams are generally the most common and reoccurring problem encountered when using any printer. Paper may jam anywhere along the paper path—from the paper tray to the output tray. Sensors within the printer constantly monitor paper travel, so when a sheet of paper fails to arrive at a certain point within a specific time, the printer interprets that to mean that the paper has stopped between two sensors along the paper path. The printer then displays a Paper Jam error message that corresponds to that specific jam. When paper gets jammed inside the printer, printing stops and an error code indicating the posi- tion of the jam appears on the display. Error Code Paper Jam Location E0 At the high capacity feeder E1 At the regi sensor E2-X Between the paper feed section (front paper tray or main tray) and the toner cartridge E3 Between the toner cartridge and the fuser unit E4 At the paper exit slot E7 At the duplexer E8 At the offset output tray
