Troubleshooting, Solutions
To increase the printing temperature, you can try to adjust the “density” or “darkness” in the barcode editing software or the printer property interface;
Properly adjust the pressure of the printer. Note: the industrial machine has a special pressure adjustment device, and some desktop machines have it and some do not;
Observe the carbon belt through light to see if there are any abnormal phenomena such as white spots and white stripes;
Check whether the ribbon and the label do not match, such as resin base printed on coated paper or rough paper;
Check whether the side-press ribbon is used on the flat-bed printer or the flat-press ribbon is used on the side-press machine;
Clean the print head and rubber roller shaft with alcohol cotton;
Change to a blank label to rule out ribbon problems;
