Removing the Transportation Damper

The printer is protected during shipping by a transportation damper that you must remove before turning on the printer.

Pull the damper out, as shown in illustration 1.

Note:

Before shipping the printer, reinstall the transportation damper.

Using the Power Switch Cover

WARNING:

If an accident occurs with the power switch cover attached, unplug the power cord immediately. Continued use may cause fire.

The enclosed power switch cover ensures that the power switch is not pressed accidentally. To use this cover, install it as shown in illustration 2.

Installing the Paper Rolls

Note:

Use only paper rolls that meet the specifications.

1. Make sure the leading edge of the paper is straight.
2. Turn on the printer and open the printer cover.
3. Insert paper rolls on both the receipt and journal sides of the printer, as shown in illustration 3. (The journal roll is on the right in this illustration.)
4. For each roll, insert the tip of the paper into the paper inlet and push it in until it is automatically detected and fed into the printer. See illustration 4.
5. Tear off the receipt paper on the cutter. If the paper was not fed far enough, press the RECEIPT FEED button to feed additional paper.
6. Insert the tip of the journal paper into the groove in the take-up spool and rotate the spool two or three times to secure the paper. See illustration 5. If not enough paper was fed, press JOURNAL/SLIP FEED to feed more.
7. Install the take-up spool and close the printer cover.
8. To remove the journal paper roll, first lift the take-up spool and cut the paper. Then remove the take-up spool. See illustration 6.
9. For either a journal or receipt paper roll, next press the release lever (marked PRESS) on the appropriate side of the printer, pull out the paper, and remove the roll.

Inserting Slip Paper

Notes:

Do not use wrinkled, folded, or curled paper.

Use only slip paper that matches the printer's specifications.

To prevent paper jams, install both paper rolls in the printer even if you plan to print only on slip paper.

1. When the SLIP LED flashes, insert slip paper, using the right edge of the slip paper inlet as a guide. See illustration 7.

2. When the printer detects the paper, it automatically draws it in and begins printing.

CAUTION:

Be sure to put the caution label exactly in the position shown. If you put it another place, such as over the slip paper inlet, the printer may be damaged.

Installing a Ribbon

Use the EPSON ERC-31. The use of any ribbon cassettes other than those approved by Epson may damage the printer and will void the warranty.

1. Turn the printer on and open the ribbon cover.
2. Turn the ribbon cassette's knob 2 or 3 times in the direction of the arrow in illustration 8 to take up any slack.
3. Insert the ribbon in the printer and rotate the cassette's knob 2 or 3 more times to place the ribbon in the correct position.
4. Make sure the ribbon is installed in front of the print head without wrinkles or creases.
5. To remove the ribbon cassette, grasp the ribbon cassette's tab and pull it out of the printer.

Using the MICR Reader (Option)

The optional, factory-installed magnetic ink character recognition (MICR) reader lets the printer read MICR ink on personal checks.

CAUTION:

To prevent paper jams, be sure both paper rolls are installed. Do not insert checks with staples in them; do not insert wrinkled checks.

1. The SLIP light flashes.

2. Insert the check face down, with the MICR characters on the right-hand side.

3. Insert the check straight into the inlet, using the right edge of the inlet as a guide, as far as the check will go. See illustration 9.

4. The printer starts drawing the check in. Let go of the check immediately. The SLIP LED goes from blinking to on.

5. When MICR reading is complete, the printer ejects the check and the SLIP LED starts blinking again.

6. Remove the check by pulling it straight out (not at an angle). The SLIP LED goes off.

Cleaning the Optional MICR Mechanism

Clean the MICR head and MICR roller every 6000 passes or once a month.

Note:

If you encounter frequent MICR reading errors, use the procedure below.

For the MICR head

Use a moistened cleaning sheet, such as PRESAT brand (KIC) "Check Reader Cleaning Card" or an equivalent commercially available cleaning sheet.

For the MICR feed roller

Use an adhesive cleaning sheet available from Epson. Contact your dealer.

Cleaning procedure

Use this procedure for both cleaning sheets.

1. Load both paper rolls into the printer; then turn off the power.
2. Open the front cover and turn the power back on while holding down the JOURNAL/SLIP button.
3. Press the JOURNAL/SLIP button 3 times.
4. Close the front cover (the SLIP LED flashes).

English

1. Follow the instructions on the cleaning sheet. You will insert the cleaning sheet the same way you insert a normal check.
2. When the sheet is ejected, remove it from the printer; then turn off the power.

Troubleshooting

LEDs on the control panel do not come on

Check the power cable and power outlet. If the outlet is controlled by a switch or timer, use another outlet.

ERROR LED is on (not flashing) with no printing

If RECEIPT OUT or JOURNAL OUT is on, a paper roll is not installed or nearly out. If these LEDs are off, the cover is not closed properly.

ERROR LED is flashing with no printing (and no paper jam)

The print head may be overheated. Printing resumes after the print head cools. If this does not occur, turn the printer off for 10 seconds and then back on. If there is still a problem, contact a qualified servicer.

The printer appears to be printing, but nothing is printed

Check ribbon installation and ribbon wear.

A line of dots is missing

The print head may be damaged. Stop printing and contact a qualified servicer.

Removing Jammed Paper

CAUTION:

Do not touch the print head because it can be very hot after printing.

1. Turn the printer off and open the printer cover.
2. For a journal roll paper jam, cut with scissors or a knife, as shown in illustration 10, and remove the take-up spool.

3. Cut the paper from the paper rolls as shown in illustration 11.

4. If paper is caught in the automatic cutter, open the cutter blade by turning the gear in the direction shown in illustration 12.

1. Move the OPEN LOCK lever on each side of the printer in the direction shown in illustration 13; the cutter opens automatically.
   6.Pull the paper out gently. If it tears,remove any pieces.
2. If necessary, remove the print head cover. Loosen the screw on the right as shown in illustration 14. (Replace it by sliding the tab in the slot, and fasten the screw.)
3. After clearing all paper, close and lock the cutter unit (lock both locks), and reinstall the paper rolls.
