Thermal paper not printing

There are several possible reasons why a Canon autoref thermal printer may not be printing consistently. Here are some troubleshooting steps that can help fix the issue:

1. Check the paper roll: Make sure that the paper roll is adequately loaded and aligned. If the paper is not loaded correctly, it can cause the printer to stop printing. Also, could you check if the paper roll is the correct size and type, as the printer's manual specifies?

2. Clean the print head: Over time, dust and debris can accumulate on the print head, causing it to malfunction. To clean the print head, turn off the printer and unplug it from the power source. Then, use a soft cloth or cotton swab dipped in alcohol to gently clean the print head.

3. Check the power supply: If the printer is not receiving enough power, it may not function properly. Ensure the power cord is securely plugged into the printer and the power outlet. Also, check if there are any loose connections or damaged wires.

4. Update or reinstall drivers: If none of the above steps work, try updating or reinstalling the printer drivers. Go to Canon's website and download the latest drivers for your printer model. Follow the instructions to install them on your computer.

If none of these steps work for you, you can contact Canon customer support for more help.

To load paper into the Casio DR-T220 thermal printer calculator, follow these steps:

1. Open the printer cover by pressing the release button located at the front of the calculator.
2. Carefully insert the roll of thermal paper into the printer with the paper facing forward, and the end of the paper coming out of the top of the roll.
3. Adjust the paper guide to fit snugly against the paper roll.
4. Close the printer cover.
5. Turn on the calculator and press the "Feed" button to advance the paper to the correct position for printing.

Please Note: Be sure to use the correct type of thermal paper for your calculator, as specified in the user manual.

i know you stated you put the paper in correctlyin the printer but if the thermal reactive side of the paper is not facing the print head the thermal paper won't print on the wrong side of the paper. it will load into the printer and seem ok but the heat on the wrong side of the paper will not react and show any writing. Can you try turning the paper over in the printer feed holder so the other side of the paper faces the print head and give it another test .

There are various responses regarding the operation of the printer on the Omni. Use the following to guide you through resolving this problem. Terminal Response Probable Cause Action Taken No Receipt

Are you trying to print in thermal or thermal transfer mode? If thermal transfer mode, do you have the ribbon install correctly with the coated side facing towards the label? If using thermal mode, are you using thermal paper and are you trying to print on the coated side? Hold the feed button down and turn the printer on. Hold it down until the light stops flashing. At this point the printer will print a diagnostic dump. If nothing prints then either you have the media loaded wrong or something else is wrong with the printer.

LetraTag label makers are thermal printers, so they don't use ink - just batteries and LetraTAG tapes.
When the print starts to fade it's time to put new batteries in.

1. disconnect printer from computer, turn off
2. re-seat thermal paper, make sure it's loaded correctly
3. press and hold paper feed button while turning the printer on
4. if print test is successful, reconnect to computer
5. print test page from printer driver

On the Selphy printers you put the paper on the front tray just up to the rollers. When you print the paper is drawn in toward the rear, and then prints on the way back out to the front tray.

if you are using software that using printer please the s600 printer driver to direct thermal mode to solve the problem.

According to the Manual, when both the Access and Paper light go on simultaneously, there is a paper jam. Check to see if there is, also check to make sure the paper is loading from your tray correctly. You have the paper face down right?
Turn off the printer after you fix he jam or paper, and turn back on before you try to print again.
Hope this helps
