Grounding the Printer You need an appropriate ground wire to ground your printer. Recommended wire is described below. Thickness of wire: AWG 18 or equivalent Diameter of terminal to be attached: 3.2 1. Make sure that the printer is turned off. 2. Connect the ground wire to the printer using the FG screw on the back of the printer, as shown.
Connecting the Power Supply This printer requires an external power supply. The EPSON Power Supply PS-150 is recommended. CAUTION: Using an incorrect power supply can cause serious damage to the printer. 1. Make sure that the power supply is turned off. 2. Plug the power supply’s cable into the printer’s connector as shown below. Note that the flat side of the connector faces up.
3. Plug the power cord into an outlet. Installing the Ribbon Be sure to use a ribbon cassette that meets the printer’s specifications. The EPSON ERC-27 is recommended. Note: For instructions on replacing a used ribbon, see Chapter 2. 1. Turn the printer on using the power switch on its left side. 2. Press the RELEASE button to turn the light on. This puts the printer in the paper release mode. 3. Turn the printer off.
CAUTION: Be sure to perform the steps above because it is necessary to make sure that the printer is in the paper release mode before you install the ribbon cassette. 4. Open the printer cover by slightly pressing the ridges on the top left and pulling the cover forward, as shown in the illustration below. 5. Check to see that the ribbon in the cassette is not creased or twisted. Then turn the feed knob in the direction of the arrow on the ribbon cassette to take up any slack in the ribbon.
6. Carefully insert the ribbon cassette in the printer as shown in the illustration below. Notice exactly where the ribbon must go. 7. Then push firmly on the right side and then the left side of the ribbon cartridge until each side clicks into place.
8. To put the cover back on the printer, first align the left and insert the tab on the top; then press the bottom until it clicks into place, as shown below. Inserting Paper Note: Do not use wrinkled or curled paper. For full information and specifications on the paper you can use, see Chapter 4. To insert paper, follow these steps: 1. Make sure that a ribbon cassette is installed in the printer. 2. Turn on the printer. The POWER light comes on. 3. Press the RELEASE button.
4. Insert the paper from either the front or the side, as shown in the illustration below. Insert the paper into the printer until it is stopped by the form stopper. The markings on the side of the printer can also be used to judge how far to insert paper. 5. Check the PAPER OUT light. When you insert the paper correctly, the PAPER OUT light goes out. If the PAPER OUT light is still on, remove the paper and re-insert it.
3. While holding down the RELEASE button, turn the printer back on. 4. Remove your finger from the RELEASE button. The printer prints the current printer settings and then eject the paper. 5. Press the RELEASE button to eject the paper completely and insert new paper to begin the second part of the test. After the printer prints a pattern, it prints the following message: ***completed*** The printer ejects the paper; then enters the normal mode.
2. Turn the printer over and locate the DIP switches, as shown below. 3. Notice that ON is marked on the set of switches. Use tweezers or another narrow tool to move the switches. 4. Use the following tables to set the DIP switches.

Chapter 2 Using the Printer The control panel has three buttons and three lights. Buttons All three of these buttons can be disabled or enabled by the ESC c 5 command. RELEASE Pressing this button moves the rollers so that paper can be inserted or removed. REVERSE Feeds the paper backward based on the line feed amount set by ESC 2 and ESC 3. FORWARD Feeds the paper forward based on the line feed amount set by ESC 2 and ESC 3. You can also use the RELEASE button to start a self test.
RELEASE This light is on when the printer is in the paper release mode and it is off when the printer is in the clamp mode. Paper can be inserted only when the printer is in the paper release mode. This light blinks to indicate an error condition in the following cases: ❏ Paper jam ❏ Home position error ❏ Timing error ❏ Drive circuit error ❏ Power supply voltage error If this light blinks, turn off the printer, make sure that no paper is jammed in it, and then turn it back on.
Then remove the used ribbon by grasping the handle and pulling straight out, as shown by the arrow in the illustration below. Then follow the rest of the steps in “Installing the Ribbon” in Chapter 1.
Chapter 3 Troubleshooting This chapter gives the solutions to some printer problems. Power problems The POWER light does not come on. Make sure that the power supply cables are correctly plugged into the printer, the power unit, and to the power outlet. Make sure that power is supplied to the power outlet. If the outlet is controlled by a switch or timer, use another outlet. Printing problems The PAPER OUT light is on and nothing is printed.

Chapter 5 Commands Command Notation [Name] [Format] The name of the command. The code sequence. ASCII indicates the ASCII equivalents. Hex indicates the hexadecimal equivalents. Decimal indicates the decimal equivalents. [ ]k indicates the contents of the [ ] should be repeated k times. [Range] Gives the allowable ranges for the arguments. [Description] Describes the function of the command. [Notes] Provides important information on setting and using the printer command, if necessary.
Control Commands HT [Name] [Format] Horizontal tab ASCII HT Hex 09 Decimal 9 [Description] Moves the print position to the next horizontal tab position. [Notes] • Horizontal tab positions are set with ESC D. • Ignored unless the next horizontal tab position has been set. • The default tab positions are at intervals of 8 characters in the 5 x 7 font 9th column, 17th column, 25th column,. . . ).
[Description] Prints the data in the print buffer and returns to standard mode. [Notes] • The buffer data is deleted after being printed. • The printer does not execute paper ejection. • This command sets the print position to the beginning of the line. [Reference] ESC L CR [Name] [Format] Print and carriage return ASCII CR Hex 0D Decimal 13 [Description] When auto-line feed is enabled, this command functions in the same way as LF. When auto-line feed is disabled, this command is ignored.
• This command should not be used within the data sequence of another command that consists of 2 or more bytes. For example, If you attempt to transmit ESC 3 n to the printer, but DTR (DSR for the host computer) goes to MARK before n is transmitted and then DLE EOT 3 interrupts before n is received, the code <10>H for DLE EOT 3 is processed as the code for ESC 3 <10>H.
