Frequently Asked Questions

Analysis of Problems

The printing temperature is inappropriate, and it may be too low;
The pressure of the printer head is too low;
The ribbon itself does not work properly, with problems such as exposed spots and lines, etc.;
The ribbon does not match the label, such as using resin ribbon to print on coated paper or rough paper;
The type of ribbon does not match the type of printer;
The printer head or platen roller is dirty.
There are uneven printing materials on the label for printing.

Troubleshooting and solutions
  • Increase the printing temperature. Try to adjust the "Density" or "Darkness" in the barcode editing software or the interface of printer properties;
  • Adjust the printer's pressure appropriately. Note: Industrial machines have special pressure adjustment devices. Some desktop machines have such devices while others don't;
  • Check if the ribbon does not match the label, such as use resin ribbon to print on coated paper or rough paper.
  • Check whether a near-edge ribbon is used on a flat-head printer or whether a flat-head ribbon is used on the near-edge machine printer;
  • Clean the printer head and platen roller with alcohol cotton;
  • Replace with blank labels to eliminate ribbon problems;
Analysis of Problems

The ribbon coating is uneven back coating or ink layer;
The printer head or platen roller is dirty;
The printer pressure is not even;
One side of the platen roller is worn.

Troubleshooting and solutions
  • Observe whether there are obvious differences in the ribbon coating;
  • Clean the printer head and platen roller with alcohol cotton;
  • Adjust the left-side and right-side pressure of the printer. Note: Industrial printers have special pressure adjustment devices. Some desktop printers have such devices and others don't;
  • Check whether the platen roller is worn. If it is severely worn, the only option is replacing it with a new one.
Analysis of Problems

The ribbon itself is wrinkled.
Yazıcı kafası kirli.
The printer head is dirty.
The printer head has broken pins (may be false broken);
The left and right pressure of the printer head is uneven, which causes the ribbon to tilt and wrinkle when printing.
The printer baffle is loose.
The printer transition roller is loose, causing the ribbon to be wrinkled before it enters the printer head.
The printing temperature is too high, causing the carrier to be scalded.

Troubleshooting and solutions
  • Observe whether the ribbon is obviously wrinkled and try another roll to see if the same condition exists;
  • Clean the printer head with an alcohol cotton ball.
  • First, clean the printer head area with exposed lines using alcohol cotton and try it again. If there are still exposed lines after cleaning, it proves that the printer head has broken pins and it is recommended to replace the printer head;
  • Adjust the printer head pressure to see if it improves.
  • Observe whether the metal baffle where the ribbon comes out of the printer head is loose and can be adjusted tightly;
  • Check whether the metal transition roller where the ribbon enters the printer head is loose and needs to be tightened;
  • Lower the printing temperature to see if it improves.
Analysis of Problems

The ribbon itself has regular missed coating.
The printer's rubber roller is damaged partly.
There are regular oil stains and glue spills on the label surface.

Troubleshooting and solutions
  • Check whether the ribbon has regular missed coating through light.
  • Check whether the printer's rubber roller has damaged spots or pits and replace it if any (the rubber roller cannot be repaired);
  • Try another roll of labels to see if it improves.
Analysis of Problems

The ribbon has miss backcoating.
The fracture surface of the ribbon is damaged.
The printing temperature is too high.
The printer head pressure is too high.

Troubleshooting and solutions
  • Place a self-adhesive tape on the backcoating of the ribbon to see if it is easy to remove the tape from the ribbon. If it is difficult to remove, it can be concluded that there is miss backcoating.
  • Check whether there are nicks or burrs on the fracture surface of the ribbon and gently pull the ribbon to see if it is easy to break;
  • When the printing is sharp, reduce the printing temperature as much as possible.
  • Adjust the printer pressure to reduce the pressure of the printer head as much as possible on the premise of ensuring sharp print;
Analysis of Problems

The ribbon is not completely dry.
The printer pressure is too high.
The label is too thick.
The printer has backfeed during the printing process.

Troubleshooting and solutions
  • Unfold a section of ribbon on the platform and gently press the ink layer with your hands to see if there is a lot sticking to your hands;
  • Reduce the pressure of the printer head.
  • There will be indentations if the label is too thick. Adjust the printer pressure appropriately according to the thickness of the label;
  • Due to the abnormal printer settings during the printing process, there will be backfeed for each label or every few labels, resulting in friction traces of backfeed.
Analysis of Problems

The backcoating of the ribbon is rough and the backcoating chemical is not enough, resulting in large friction.
The printer pressure is too high.
The printer is set to "thermal" mode.

Troubleshooting and solutions
  • Place a self-adhesive tape on the backcoating of the ribbon to see if it is easy to remove the tape from the ribbon. If it is difficult to remove, it can be concluded that there is missed backcoating.
  • Adjust the printer pressure to reduce the printer head pressure on the premise of ensuring sharp print;
  • Change "Printing Preferences" of the printer back to "Thermal Transfer Mode".
Analysis of Problems

The ribbon itself has too much static electricity.
The printer is not grounded.

Troubleshooting and solutions
  • When printing, place the machine on a conductive platform if possible. If not possible, a static elimination device can be installed on the printer.
  • Ground the printer.
Analysis of Problems

The ribbon paper core is deformed, and there is deformation due to compression.
The burrs of the ribbon paper core are too large and there are too many paper scraps.
The printer unwinding shaft is deformed and not straight.
If the ribbon slips on the unwinding shaft, check whether the flat spring of the unwinding shaft fails to work.

Troubleshooting and solutions
  • Observe whether the paper core is obviously deformed and whether it has become an obvious oval. If so, just return it.
  • Observe whether the paper core has any paper scraps or burrs. Clean it up and try again. If it still doesn't work, it may be deformed, so just return it.
  • Check whether the printer's unwinding shaft is deformed or whether there is debris sticking to the shaft. If so, just replace or clean the unwinding shaft.
  • If so, replace the flat spring. If not, the inner diameter of the paper core may be too large. Just stick one or two labels on the inner wall.
Analysis of Problems

Wrinkles are caused upon slitting.

Troubleshooting and solutions
  • It can be clearly seen from the appearance whether there are wrinkles, and if so, just return it.
