When printing a receipt, you encounter one of the following receipt printer errors:

• Cash drawer won't open, and the receipt printer won't print.
• Receipt printer prints blank receipts.
  

Solutions:

• Make sure the thermal printer is turned on and has paper in it. Then, check that the cash drawer is not locked. 
• Open the receipt printer. Make sure there is paper, with the correct side facing up. Reset the paper, close the printer and hit the feed button, just to double-check.
  

  
  

  
  
  

• Check paper orientation, use the cover open lever to open the roll paper cover. Push in the direction of the arrow towards the top/back of the printer.

  

  2. Remove the used roll paper core if any, and insert the roll paper. The correct direction of the paper is shown in the illustration below.

  

  3. Pull out some paper, and close the roll paper cover. When the printer power is on, the roll paper is automatically cut.
