This is caused when mechanical parts of the printer get out of alignment. This happens only rarely and you may never experience it at all throughout the life of the printer. If you do have problems, use the following procedure to correct it.

1.Make sure that paper is loaded in the printer.

2.Turn off the printer.

3.While holding down the control panel’s SET/PARK/EJECT and LINE FEED buttons, turn the printer back on to enter the Dot Adjustment Mode.

The printer will print something like the following.

Note that the printer will feed the paper forward and back each time during this operation so you can view the printout.

4.If the two lines do not align properly, use SET/PARK/EJECT to move the lower line to the left or LINE FEED to move it to the right.

The above step performs alignment for Normal-density mode only. You must make separate adjustments for the CRT graphics, Double- density, Draft-Text, Triple-density, CRT graphics II, Quadruple- density, LQ Text modes as well.

5.Press ON LINE to change to the next printing mode.

Press LINE FEED while holding down ON LINE to change to the previous printing mode.

6.Repeat the above steps for each printing mode, if necessary.

7.After making changes to the adjustments, press SET/PARK/EJECT while holding down ON LINE to exit the Dot Adjustment Mode and register your adjustments.
