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.
EJECTING 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
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.

INITIALISING MENU SETTINGS
To restore the menu settings to their initial values, carry out the

2.
Press and hold down the SEL and LF/FF buttons together
and then set the Power Switch to ON.
ML1120/ML1190 User’s Guide – Operating instructions > 55
ADJUSTING TOF POSITION
Use the following procedure to set TOF to accord with the
reference position (6.35 mm (0.25 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 45 and confirm that
the TOF (in cut sheet mode or continuous forms mode) is
6.35 mm (0.25 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.
As the paper is taken into the printer, press the LF/FF
button and the paper is taken into the 6.35 mm (0.25 in)
position.
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 +- 0.366 mm
(1/144 in), the QUIET indicator flashes and the paper cannot
be moved.
ML1120/ML1190 User’s Guide – Operating instructions > 56
When the paper is positioned at the required TOF, release
the buttons in Step 5 above.
To save this position as the TOF, press and hold down the
LOAD/EJECT and the LF/FF buttons together for 3 seconds.
NOTE
Do not turn the Platen Knob or switch off the printer during
the above procedure.
