Clearing a jam

If a paper jam or transfer roll jam occurs, the JAM indicator is on. Follow these steps to locate and remove the jam:

1.Turn off the printer; open the top cover to its full upright position.

Caution The thermal head is hot; do not touch it until it has cooled down, approximately 5 minutes. Also, do not touch the rubber rollers directly because the oil from your fingers can contaminate the rubber and cause printing problems. Use a cloth or gloves if you need to rotate the rollers.

2.If the transfer roll or paper is wound on a roller, turn the green knob to rotate the rollers and free the jammed paper or transfer roll.

3.Lift out the transfer roll tray. Check the roll for tears and wrinkles. (If the roll is damaged, replace it with a new one.) Straighten the roll and make sure that the axles on the endcaps are set snugly into the tray (refer to ÒReplacing the transfer rollÓ on page 4-17).
