You can access specific information in two ways: l In the list of bookmarks down the left hand side of your screen, click on the topic of interest to jump to the required topic. (If the bookmarks are not available, use the Table of Contents). l In the list of bookmarks click on Index to jump to the Index.
(c) 3. Pages from and to for the range of pages you specify by entering their page numbers. Click on OK.
GETTING STARTED LOCATION l Select a firm, solid surface on which to site your printer. l Allow enough space around the printer to easily access the platen knob and the various paper feed paths. l Make sure a suitable grounded power outlet is available nearby. l Read the Installation Safety Booklet. CONTENTS AND UNPACKING l If any items are missing, contact your dealer immediately. l Keep your packing materials and carton in case you ever need to ship or transport the printer.
Do not plug the printer into the AC supply until the following steps have been completed: REMOVING THE SHIPPING RESTRAINT 1. Remove any packing tape. Insert your hand in the top cover slot (2) and remove the access cover (1) by lifting it. 2 1 2. Remove the printhead shipping restraint. Keep shipping restraint for future use. 3. Reinstall the access cover.
INSTALLING/REPLACING THE RIBBON CARTRIDGE CAUTION! When replacing a Ribbon Cartridge, make sure you have the correct replacement ribbon for your printer. The wrong ribbon will not print when installed in your printer. RIBBON CARTRIDGE HANDLING l Leave unused ribbon cartridges in their packages until needed. l Careful; the ribbon ink may cause permanent stains. l Ribbon ink on skin or clothing can usually be removed with soap and water. Make sure the printer is turned OFF. 1.
2. When replacing a Ribbon Cartridge, first remove the old one. WARNING! If you are replacing the ribbon Cartridge, the printhead may be HOT! 3. Unpack the ribbon cartridge and install it on the printhead.
4. Press gently on the ribbon cartridge until you feel it click into place. CAUTION! Do not remove the ribbon shield (“X” in graphic above) from the ribbon! 5.

INSTALLING THE PLATEN KNOB If the Platen Knob is not already fitted, align the key way (a) correctly and push it firmly into place.
ADJUSTING THE HEAD GAP The head gap is the distance between the print head and the platen roller. When you use envelopes or multi-part forms you will need to have a larger gap than when using plain paper. Use the recommended head gap to ensure the best print quality and easy paper feed. CAUTION! Incorrect setting of the print head gap can cause print head damage or ribbon jams. To avoid these problems set the print head gap for the type of stationery being used.
FITTING THE PAPER SEPARATOR The Paper Separator is utilised when using single sheets (no carbons) and when using continuous stationery to separate the ingoing/ outgoing paper to prevent paper jams. It is fitted as follows: 1. Grasp the paper separator by either side, with the spring loaded stays to the rear of the printer. 2. Locate the two hooked lugs on the edges of the paper separator into the two corresponding slots in the top of the printer. 3. Release paper separator on to the top of the printer.

MAINTENANCE REPLACING THE RIBBON CARTRIDGE See “Installing/Replacing the Ribbon Cartridge’’on page 11 .
TROUBLESHOOTING GENERAL INFORMATION Here are some general things to check before proceeding with detailed troubleshooting.
The initialization string contains codes that override the panel and menu settings. To change your printer to ignore the reset code, enter the Menu Mode, go to the Set-Up group and change the setting for Reset Inhibit to Yes. The I-Prime signal will automatically override any front panel settings you have made. To eliminate this problem, enter the Menu Mode, go to the Parallel Interface group and change the setting for I-Prime to Invalid.
1. Check to be sure that the printer driver you have selected in your software matches the printer emulation. 2. Please refer to the Printer Driver section for details of emulations, then check the menu settings (see “Setting Printer Defaults” in the Operating your Printer section). 3. If you have embedded any printer commands in your software, check to be sure that you entered them correctly. Problem Ink smears on the paper when I print narrow columns. Solutions The head gap could be too close.
Solution The head gap may not be set correctly. Try moving the headgap lever to a lower setting. If that doesn’t help, the printhead may be damaged; call for service. Problem The ALARM light is flashing. Solution Try turning the printer OFF and then back ON again. If the light still blinks, call for service. Problem The Print Quality and Character Pitch keys on the front panel don't work. Solution The Operator Panel Function in the printer menu can be used to disable these buttons (Limited Function).
CLEARING PAPER JAMS Rear Feed Jams 1. Turn the printer OFF. 2. Use the platen knob to back the paper all the way out of the printer. CAUTION!
