Chapter 1 Setting Up Your Printer About Your Ink Jet Printe r ................................................................... l-2 A few precaution s ........................................................................ 1-2 Choosing the right pape r .
About Your Ink Jet Printer If you’re new to ink jet printers, you may wonder how they differ from dot matrix or laser printers. Two noticeable benefits of this technology are high print quality and quiet printing. An ink jet printer produces cost-effective, quality print results.
t2 Do not use an ink cartridge beyond its rated life expectancy. Ink cartridges are good up to the date printed on the cartridge carton. Cl When moving the ink cartridge from a cold place to a warm one, let it sit for about one hour until the ink warms to the new temperature.
To test a supply of paper, take a single sheet from the package and load it in the printer. Perform the self test and check the results. You should test both sides of the paper to determine which gives you the best quality printing. If the ink does not bleed or smear, the paper should be suitable for use with your printer.
In some locations, the power cord comes attached to the printer. The shape of the AC plug varies by country; be sure the plug included is the right shape for your location. You must remove all packing and protective materials packed with your printer before you can set it up and turn on the power.
Choosing a Place for the Printer When selecting a location for your printer, follow these guidelines: cl Ll cl ci D D cl Ll Q Place the printer on a flat, horizontal, stable surface. If the printer is tilted or at an angle, it cannot operate properly.
Plugging in the Printer 1. Make sure that the power switch is turned off. It is off when the 0 side of the switch is pressed down. 2. Check the label on the back of the printer to make sure the voltage required by the printer matches that of your electrical outlet.
Installing the Ink Cartridge Each ink cartridge contains enough ink to print about 700 pages. The exact number of pages a single cartridge can print varies according to the amount of text and graphics on each page. The first time you use your new printer, you need to charge the ink delivery system with ink.
1. Make sure the printer is turned off. 2. Hold down both the Alt and Pause buttons while you turn on the printer. Release the buttons after the printer starts initializing.
3. Open the printer cover. 4. Pull the top of the ink cartridge clamp towards you to open it. 1-10 0 Setting Up Your Printer.
5. Open the f oi package containing the ink cartridge an d 1 remove it from the protective cardboad. Make sure to remove the tape seal from the ink cartridge. 6. Lower the cartridge into the holder with the label face up and the arrow mark on the cartridge towards the arrow mark on the printer case.
7. Push the ink cartridge clamp towards the back of the printer to secure the cartridge. 8. Press the A lt button again to charge the ink delivery system. It takes about one minute. The Pause light flashes throughout the cycle and turns off when the ink charging has finished.
Testing the Printer After you charge the ink delivery system, you can use the built- in self test to make sure the printer is working properly. You can run the self test with paper from the built-in paper feeder or by feeding a sheet manually. This section describes loading paper in the paper feeder.
3. Insert a stack of paper all the way into the paper feeder with the printable surface face-down. Align the right edge of the stack with the right edge of the paper feeder. Then move the left edge guide to match the width of your paper, as shown below.
2. While holding down the FONT button, turn on the printer. (Hold down the button until the printer starts working; it takes a few seconds.) It loads a sheet of paper automatically from the paper feeder and begins the self test. The printer prints characters in each font, in the order the fonts appear on the control panel.
Follow these steps: 1. Make sure both the printer and computer are turned off. 2. Plug the cable connector securely into the printer’s interface connector. 3. Squeeze the wire clips together until they lock in place on both sides. If your cable has a ground wire, connect it to the ground connector above the interface connector.
Setting Up Your Software Programs Most application programs let you specify the type of printer you use so that the program can take full advantage of the printer’s features. Many of these programs provide an installation or setup menu that presents a list of printers.
Tips for Using the Paper Feeder Following the tips below will give you the best performance when printing with the paper feeder. Q Load paper into the paper feeder before you turn on the printer and send data. When the printer receives data from the computer, it loads a single sheet automatically and begins to print.
Chapter 2 Using Other Printer Functions Loading Paper Manuall y ..................................................................... 2-2 Paper size s .................................................................................... 2-2 Printing on single sheet s .
Loading Paper Manually You can load single sheets of paper or envelopes from the manual feed slot without removing the paper supply from the paper feeder. Note: 7%~ instructions in this section describe loading paper by hand in the rnunual~feed slot. lf you want instructions for using the paperfeeder, see page l-1 8 it? Chapter 3.
2. Insert a single sheet of paper into the slot until it meets resistance, aligning the right edge of the paper with the arrow mark on the printer. The printer automatically loads the sheet. Note: lf the sheet does not load straight, press the Load/Eject button fc $ect it.
Printing on envelopes You can also use the manual feed slot to print on individual envelopes. 1. Turn on the printer and open the printer cover. 2. Turn the paper-thickness lever clockwise as far as it will go.
4. 5. Insert an envelope into the manual feed slot with the wide end at the top entering the printer first, and the printable side face-up, until it meets resistance. The printer loads the envelope to the print position automatically. Send data from your computer.
Operating the Control Panel The printer control panel gives you easy control over most common printer operations. It consists of indicator lights and buttons. 0 Data 0 Paper Out 0 Pause f-l 7 I rl Indicator lights Pause On when printing is paused Font Indicate the current font setting.
Economy On when the economy printing mode is selected. When this mode is selected, the printer uses fewer dots per character. The print speed is the same in both economy and LQ mode, but the economy mode uses less ink. This mode is ideal for rough drafts and editing work.
Alt Hold down this button for several seconds to move the print head to the ink cartridge replace position when the printer is paused. The Alt button also alters the functions of the other buttons. Hold down the Alt button and press another button to change the functions as follows: PRINT HEAD CLENINC (Alt + Pause) Starts print head cleaning cycle.
Adjusting the loading position The loading position is the position of the paper when the printer loads it from the paper feeder or the manual feed slot. If printing is too high or low on the page, you can change the loading position with the micro-feed feature as follows: 1.
Note: Cl The printer has a minimum and maximum loading position. l,f you try to move the loading position beyond these limits, the printer beeps and the paper stops moving. Ll When the paper reaches thefactory-set loading position, the printer beeps. Use thefactory setting as a reference point when adjusting the loading position.
Selecting Character Fonts Your printer has eight built-in character fonts including two new Epson fonts: the Epson Roman T and Epson Sans Serif H. (Roman T is similar to the TimeP’ font; Sans Serif H is similar to HelveticaWe) Press the Font button to select from the eight fonts listed on the control panel.
Scalable Fonts The size of the Roman, Sans Serif, Roman T, and Sans Serif H fonts can be selected from 8 to 32 points in 2-point increments by using your application program or by sending an ESC/P 2 command. See the documentation that came with your application program for information on selecting the size of scalable fonts.
Using the Default-Settings Mode Your printer comes with a series of internal settings that control a variety of printer functions, such as print direction and auto line feed. Because these settings take effect each time you turn on the printer, they are called default settings.
Default settings descriptions Character table Character tables contain the characters and symbols used by different languages. The printer prints text with the selected character table. When you select this feature, the font lights on the control panel go on or off to indicate the current selection.
Auto line feed When the auto line feed feature is on, each carriage return (CR) code is accompanied by a line feed (LF) code. If your printed text is unexpectedly double-spaced, set this feature to off. If text lines print on top of each other, set it to on.
After you press the A lt button, the printer prints the current default settings and the next instruction in the language you selected. Wait until printing is finished, then go to the next step. 4. To move to the feature you want to change, press the Alt button until the Data, Paper Out, and Ink Out lights indicate the appropriate selection.
Character table Auto print direction Network I/F mode Mixed text/graphics mode Auto line feed ITALIC U.S.A ON OFF OFF OFF --- Using the default setting mode --- (Stepl) Select menu(a)-(e) by pressing the ALT switch. DATA, PAPER OUT, and INK OUT LEDs show menu selected at that time.
6. Repeat steps 4 and 5 to make all of your changes. 7. To exit the default-settings mode, turn the printer off. Note: Ll You may exit the default-settings mode any time by turning off the printer. Amy changes you have made remain in effect until you chanige them again.
Chapter 3 Maintenance and Troubleshooting Replacing the Ink Cartridg e ............................................................... . 3-2 Cleaning the Print Hea d ..................................................................... . 3-3 Cleaning the Printe r .
Replacing the Ink Cartridge When the Ink Out light on the control panel flashes, the ink in the ink cartridge is low. The printer will continue printing until the cartridge is completely empty. When it is out of ink, the printer stops and the Ink Out light stays on.
4. Lift the cartridge out of the printer and dispose of it properly. Do not take the used cartridge apart or try to refill it. q Caution: If ink does get on your hands, wash them thoroughly with soap and water. l f ink gets into your eyes,flush them immediately with water.
Cleaning the Printer To keep your printer operating at its best, you should clean it thoroughly several times a year. 1. 2. 3. 4. 5. Make sure the printer is turned off. Remove any paper from the paper feeder. Use a soft brush to carefully brush away all dust and dirt.
Note: Do mt rt’mozv the hk cartridge, where tratisporting. 2. Unplug the power cord from the electrical outlet; then disconnect the interface cable from the printer. 3. 4. 5. Remove the paper from the paper feeder. Attach the protective material to the printer.
Plug another electrical device into the outlet to determine whether it is working. The lights come on briefly but then go off and stay off. Check that the printer’s voltage rating matches the voltage of your electrical outlet. If the voltages do not match, unplug the printer and contact your dealer immediately.
The Pause light is off but nothing prints. The interface cable may not be plugged in securely. Check both ends of the cable between the printer and the computer. Make sure your interface cable meets both the printer and computer specifications. Make sure that your software is properly set up for your printer.
Dots are missing in printed characters or graphics. The print head nozzles may be clogged. Hold down the AH button and press the Pause button for two seconds to clean the print head. See “Cleaning the Print Head” earlier in this chapter. Set the Mixed text/graphics mode to on in the default-settings mode.
You may not be printing on the correct side of the paper. Test both sides to determine which side gives you the best print quality. Your paper may be moist or damp. Do not store your paper in a damp or humid environment. The typestyles or characters set with your software do not print.
The text prints an extra blank line between each text line. Set auto line feed to off in the default-settings mode so that two line-feed signals are not sent. See “Using the Default-Settings Mode” in Chapter 2. Line spacing is incorrect. Adjust the line-space setting with your software.
The ejected paper is wrinkled. The paper is too thin or is damp. Make sure that the paper you are using meets the specifications. See “Technical Specifications” in the Appendix. Do not store your paper in a damp or humid environment. The paper does not fully eject.
3. 4. 5. Pull the paper out gently. If the paper tears, make sure you remove any remaining pieces. If the paper is caught in the paper ejection area, gently pull it out of the printer. Push the access panel back onto the rear of the printer and close the printer cover and the paper feeder cover.
