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.

7

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.

CAUTION:

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

1. Turn the printer on and open the printer 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.

English

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.

TM-U950 User’s Manual 7

English

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 printer 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 printer cover (the SLIP LED flashes).

5. Follow the instructions on the cleaning sheet. You will insert
the cleaning sheet the same way you insert a normal check.

6. 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 printer 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.
