Troubleshooting Paper Jam and Continuous Printing Issues

Paper jams and continuous printing problems may occur with both thermal and dot‑matrix printers. Fortunately, most issues can be resolved with a few simple checks.

(TM‑T88V Thermal Printer & TM‑U220B Dot‑Matrix Printer) 

A) Thermal Printer (TM‑T88V)

Reload the Paper Correctly 

  • Open the paper cover. 
  • Make sure the paper roll feeds from underneath toward the cutter. 
  • Reseat the roll and close the cover firmly. 

Incorrect loading is one of the most frequent causes of jams. 

Clear a Cutter Jam 

If the cutter is stuck or the Error light is flashing: 

  • Turn the printer OFF 
  • Open the cutter cover 
  • Locate the small manual‑feed knob 
  • Turn the knob until the triangle mark appears (this resets the blade) 
  • Remove any jammed paper 
  • Reseat the paper roll and close the cover 

⚠ Warning: The thermal print head can be hot after printing. Allow it to cool before touching internal components. 

B) Dot‑Matrix Printer (TM‑U220B)

Reload Paper & Close the Cover Firmly 

  • Ensure the paper is aligned straight in the paper path. 
  • Closing the cover tightly loose covers can cause feeding issues. 

⚠ Avoid placing fingers near the cutter blade. 

Autocutter Stuck? 

If the cutter doesn't return to its normal position: 

  • Refer to the printer’s manual for the cutter return/reset procedure 
  • Once the cutter resets, reload paper and close the cover 

Continuous Printing / Printer Won’t Stop Printing 

Sometimes the printer keeps feeding paper or printing endlessly. Follow these steps: 

Check for Multiple Print Jobs 

  • Open the computer’s Print Queue in Windows Operating System
  • Open Printers & Scanners.
  • Select the printer from the list.
  • Click to open it.
  • Choose Open queue.
  • Cancel all unnecessary or repeated print jobs 
Ifqueue still does not clear > follow help guide on Restaring printer spooler service


Close the Printer Cover Tightly 

A loosely closed cover—especially on dot‑matrix printers—can cause continuous feeding. 

Power Cycle the Printer 

  • Turn the printer OFF 
  • Wait 5 seconds 
  • Turn it ON again 

This clears minor software or mechanical glitches. 

Check the Network Connection (Ethernet Connection)

  • Reseat the Ethernet/network cable 
  • Power cycle both the printer and the network device (if connected directly) 
  • Try printing again
