RODUCING A TEST PRINT
To check that your printer is operational, produce a test print on
a sheet of 80 gsm A4 paper (for example) as follows:
CAUTION!
Allow at least 5 seconds between turning the printer
ON after turning it OFF. A shorter time interval
between turning ON/OFF operations may cause
printer power failure.
Do not turn the printer OFF while it is printing as this
may result in damage to the print head.
1. Turn the printer Power Switch to OFF.
2. Set the Paper Type Lever to cut sheet.
3. Remove the Access Cover and set the Paper Thickness
Lever to position 1.
4. Press and hold the LF/FF and the LOAD/EJECT buttons and
turn the Power Switch to ON. The ALARM indicator should
be illuminated to indicate that there is no paper in the
printer.
5. With the long side of the paper against the paper guide,
insert the paper carefully into the printer. The printer will
automatically grip the paper and start the test print.
NOTE
If required, you can pause the test print by pressing the SEL
button and then resume the test print by again pressing the
SEL button.
6. When the test print has completed, the paper is
automatically ejected.
NOTE
If you want to stop the test print for any reason, press the SEL
button followed by the LOAD/EJECT button to eject the paper.
Turn the printer Power Switch to OFF.

gripped.
NOTE
Ensure that the paper is accurately aligned along the Paper
Guide to avoid the possibility of skew printing.
When printing an envelope, do not fold up the flap. A flap
aligned along the Paper Guide can lead to skew printing.
E
JECTING CUT SHEET PAPER
When the printer reaches the end of the cut sheet page it
automatically ejects the page. If required, add another sheet for
the printer to continue printing from where it left off.
To eject a cut sheet left in the printer, carry out the following:
1. Press the SEL button to put the printer off-line.
2. Press the LOAD/EJECT button and the paper is ejected to
the Paper Tray.
NOTE
Paper longer than A4 length (297 mm) may overlap and
possibly fall off the Paper Tray.

2. Position the continuous forms supply directly below the
printer, no more than 3 cm left or right of the printer
paper path.
3. Ensure the rear of the printer is close to and parallel with
the edge of the surface and at least 60 cm from any wall.
F
EEDING CONTINUOUS FORMS (REAR FEED

ETTING THE PAPER THICKNESS LEVER
There are 6 lever positions, the first 5 for printing purposes and
the sixth to facilitate ribbon replacement.:
Set the Paper Thickness lever for different paper types as follows:
PAPER TYPE LEVER POSITION
1 2 3 4 5 - 6
Cut sheet paper See below
52 – 80 gsm X
81 – 127 gsm X
Envelope X
Carbon paper or Pressuresensitive paper (40 gsm)
2 part X
3 part X
4 part X
5 part X
6 part X
See below
Set the Paper Thickness lever for overall paper thickness as
follows:
OVERALL PAPER THICKNESS LEVER POSITION
0.06 – 0.10 mm 1
0.11 – 0.18 mm 2
0.19 – 0.25 mm 3
0.26 – 0.32 mm 4
0.33 – 0.39 mm 5
0.40 – 0.46 mm 6
ML1120/ML1190 eco User’s Guide – Paper handling > 40
Page 41
NOTE
Printing with lever positions 5 – 6 is not guaranteed.
If the lever position does not suit the paper thickness, paper
feeding and printing may not work properly.
Do not print bankbooks to avoid possible pin breakage/ribbon
snagging.
Printing can be carried out with the lever position set to 4 for
paper thickness up to 0.32 mm.
When lever positions 5-6 are selected, printing quality for
carbon paper may decline resulting in illegible characters for
example.

TOF
POSITION
Use the following procedure to set TOF to accord with the
reference position (23.28 mm (11/12 in)). The reference position
refers to the first line of the paper i.e. the position to which the
printer feeds the paper when automatically loading the paper.
NOTE
Adjusting of TOF can be done in cut sheet mode or continuous
forms mode.
1. Print out the menu settings of the printer as in
“Confirming current settings” on page 53 and confirm that
the TOF (in cut sheet mode or continuous forms mode) is
23.28 mm (11/12 in).
2. Set the Paper Type lever to the required paper type.
3. When continuous forms are used, place the paper on the
Pin Tractor.
For cut sheet mode, do not insert the paper at this stage.
4. In continuous forms mode, press the LOAD/EJECT button.
In cut sheet mode, place the paper in the Paper Tray and
press LOAD/EJECT.
5. In off-line mode, press the following buttons to adjust the
first printing line:
To feed the paper forward by a small amount, press and
hold down the LOAD/EJECT button and then press the SEL
button.To feed the paper backward by a small amount,
press and hold down the LOAD/EJECT button and then
press the LF/FF button.
NOTE
If the specified correction range is more than +- 3.53mm (20/
144 in) for ML1120 eco and +- 4.23 mm (30/180 in) for
ML1190 eco, the paper cannot be moved.
When the paper is positioned at the required TOF, release
the buttons in Step 5 above.
