paper on the Input Tray (2) into the printer until it is gripped.
1
2
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
Paper longer than A4 length (297 mm) may overlap and possibly fall off the Paper Tray.
ML1120/ML1190 User’s Guide – Paper handling > 20
LOADING CONTINUOUS FORMS
SETTING UP CONTINUOUS FORMS
To avoid paper feeding problems, carry out the following:
1.Check your printer is on a surface approximately 75 cm above the floor.
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.
FEEDING CONTINUOUS FORMS (REAR FEED)
1.Ensure that the printer is turned ON.
NOTE
If there is a cut sheet in the printer, eject it as described in “Ejecting cut sheet paper” on page 20.
2.Set the Paper Type Lever to Continuous Forms 
ML1120/ML1190 User’s Guide – Paper handling > 21
