1.Turn the printer off and press the cover open button to open the cover.

2.Remove the jammed paper and put the roll back in the printer and close the cover. (Take care not to touch the print head.)

3.If paper is caught in the automatic cutter and the printer cover cannot be opened, open the cutter cover as shown below.

4.Then turn the knob until you see cutter blade back to the lowest position, as shown in the illustration below. This returns the cutter blade to the normal position. Also notice that there is a label near the cutter to assist you.

When paper jams, turn the knob until the cutter blade back to lower position.

5.Close the cutter cover.

6.Open the printer cover.

7.Remove the jammed paper.

Note:

Other than a paper jam, the autocutter locking up could have been caused by a foreign object such as a push pin or paper clip. If this is the case, follow the same procedure described above to return the cutter to its normal position.

Do not open the cutter cover unless you find that the paper roll cover does not open.
