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 Pressure-sensitive paper (40 gsm)					See below
2 part X
3 part X
4 part X
5 part X
6 part X

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

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 steps below.

NOTE

The values adjusted by the Adjustment menus are not initialised by the following procedure.

1. Set the Power Switch to OFF.
2. Press and hold down the SEL and LF/FF buttons together and then set the Power Switch to ON.

ADJUSTING 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.

PRINTER SPEED SETTINGS

PRINTER IMPACT MODE

When switched ON, the printer enters the impact mode selected in the menu. You can change this to normal speed, high speed and quiet printing without using the menus as follows.

(This function is enable for ML1120 eco.)

NORMAL SPEED PRINTING

Use this for standard file printing operations.

1. Ensure the SEL indicator is illuminated.
2. Hold down the SEL button and press the TEAR button.
   Status Indicator 1 turns OFF and Status Indicator 2 illuminates.

HIGH SPEED PRINTING

Use this for high speed printing.

1. Ensure the SEL indicator is illuminated.
2. Hold down the SEL button and press the TEAR button.
   Status Indicator 1 illuminates and Status Indicator 2 turns OFF.

SETTING TOF POSITION AT THE PLACE OF USER'S CHOICE

TOF position can be set at the user's choice. 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 paper.

NOTE

Adjusting of TOF can be done in cut sheet mode or continuous forms mode.

1. Move paper level to the position of the paper to be set.
2. Continuous paper: Set the paper in Pin Tractor.
3. Continuous paper: Push the LOAD/EJECT button and the paper will be fed to the printer.
   Single sheets: Set the paper in the tray and the paper will be fed to the printer.
4. Switch to off line.
5. Push the LOAD/EJECT button continuously and adjust the position of printing, start by combining the following buttons:
   Forward (minute reline): LOAD/EJECT button = SEL button
   Rear (minute reline): LOAD/EJECT button + LF/FF button

NOTE

The range set for TOF is between 2.12 mm (1/12 in) and 368/4 mm (14.5 in). Outside the range, the paper cannot be moved.

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 under the Select condition.

NOTE

Do not turn the Platen Knob or switch off the printer during the above procedure.
