What is the reason why the barcode printer does not print clearly?

In the usual label design and printing process, Zhonglang label printing software and label printer hardware are indispensable, but for the hardware printer, there will be a certain amount of wear and pollution on its interior after a long period of use, resulting in a not very good effect when we print, let's take a look at the general reasons and processing methods for unclear printing of thermal label printers.

When we finish designing and connecting the printer to print in Zhonglang label printing software, click Print, and some of the printed labels are not clear (as shown below).

The main reason for this situation is that most of the print heads are dirty and need to be cleaned, or the depth is not enough, let's take a look at the specific treatment methods:

1. Clean the print head Turn off the power state of the printer, open the top cover of the printer, the area that comes out of the frame is the print head, and clean the print head in one direction with alcohol and cotton (must be alcohol) in the shutdown state.

2. Adjust the depth of the printer If the temperature of the print head is not enough and the content of the print is not deep, you can set the density of the label printer. Here's how to set it up:

You click on the Windows Start Menu Printers & Fax (or Devices and Printers).

Right-click on the printer driver Printer Preferences option, adjust the print speed and depth, <>

3. If the printing is blurry, we can also check whether the top cover of the printer is in place, and then print by pressing the upper cover with two hands.

The above three situations can generally solve the situation of thermal printing blur, you can check and deal with it when you encounter thermal printing blur, and after processing, we can submit the printing task again in the Zhonglang label printing software for printing:

The printing is not clear, generally the life of the consumables is up, try it after replacing the original consumables.

There are several reasons why the printer is not typing clearly:

1. Insufficient toner. You can temporarily extend the life of the toner cartridge by shaking the toner evenly. If you still can't improve the print quality, install a new toner cartridge.

3. If the color of the whole page is very light, it means that the printing resolution is set too low or the "Ink Saver" mode is enabled. Adjust the print resolution and turn off the Ink Saver mode.

Go to the computer control panel to find "Printers & Fax", find the printer icon, right-click to enter [Printing Preferences] - [Graphics] to set it. This operation is used for models with ink saving.

4. Print a self-test report to check whether the life of the toner cartridge is almost up. If it arrives, you will need to replace it with a new toner cartridge.

We can check if the printer's ink is gone, or the connection on the computer is unstable, or the printer itself is malfunctioning.

Poor typing may be due to the ink running out or the machine malfunctioning.

If the printer's handwriting is not clear, you can replace the consumables directly.

If you use an inferior ribbon or the ribbon is out of date, please reinstall the ribbon with better performance.

1. Turn off the power first, then turn on the printer panel, pinch the buckles on both sides of the ribbon rack, and take the ribbon rack outward.

2. Then we gently pry open the shell of the ribbon rack along the thin seam of the ribbon rack, do not pry hard, otherwise the shell or even the ribbon will be damaged.

3. After removing the shell, pinch the gear card marked in the figure with your hand, remove the old ribbon, pay attention to the position in the lower left corner, there is a metal shrapnel, pinch it with your hand and then take the old ribbon.

4. Then we take out the prepared new ribbon, the new ribbon will be packed in a small box, we directly open the ribbon shell, and buckle the ribbon upside down in the ribbon rack, at this time, be careful not to mess up the new ribbon! When installing the new ribbon, pay attention to the gear and the shrapnel in the lower left corner.

5. Wait until the ribbon is filled, then cover the ribbon rack lid, and note that the lid and the rack box have corresponding slot seats. Once the lid is closed, pinch the seat marked on the way with your hand and rotate it counterclockwise for a few weeks to tighten the ribbon!

6. Now put the ribbon holder back into the printer, and also align the card slot seat and the ribbon and print head seat. After putting it back on, turn it on. The replacement was successful.

Was it good before? The problem is that it is not clear until the ribbon or label is replaced? If the problem arises after replacing the consumables, please check the quality of the ribbon or the label you are using; If you have been using a kind of consumables, check the print head, some machines can adjust the printing temperature, see if it can be solved, if the problem is still there, maybe the thermal head is about to break.

The problem is multifaceted: 1. Whether the ribbon matches the label paper 2, whether the temperature of the printer is adjusted 3, whether the printing position of the print head is at the best 4, whether the pressure of the printer 5, and whether the printer is damaged.

Possible causes:

1. If the pressure is not enough, adjust the pressure.

2. If you use a ribbon, check whether the ribbon is too long and the effect is not good, try to change the ribbon.

3. If it is thermal, check whether the thermal paper is stored for too long, and try to replace it with a new thermal paper.

Adjust the ribbon stitch step. x0d x0a4) is contaminated with oil stains on the surface of the printed substrate. Clean the substrate and remove contamination.

Clean the print head glyphs. x0d x0a3) ribbon is not smooth, wrinkled, etc. Check whether the ribbon winding column is fixed and displaced, and the correctness of the winding method.

Increase the temperature of the printhead appropriately. x0d x0a2) The printing pressure is too small. Increase the printing pressure appropriately.
