When we use a bar code printer, we will encounter the printed bar code or the image is not clear. Many people may think that it is a bar code software problem. In this case, the bar code software is not very important. Most bar code software only plays a role. The role of data output, this time we should first consider the problem of the printer. Then to solve the problem of unclear printing of barcode printers, we must first understand why the barcode printed by the barcode printer is not clear.
Barcode printers are not clearly printed and are likely to be:
1. The print depth may not be enough, and the temperature of the print head is raised.
2. It is also possible that the printing speed is too fast, so that the ribbon and the label only have insufficient contact time. Set the print speed to a slower speed.
3. Try pressing the print head down if the print head is pressed down. The printing can be clear, in this case, the pressure on the print head is not enough, and the pressure of the print head can be adjusted.
4. When the ribbon and the label paper do not match, it will also cause such a situation. For coated paper labels, a wax-based ribbon or a hybrid base is used. For PET, a resin ribbon is used.
If you are printing graphics, there are several reasons why an unclear problem may occur:
1. If the inferior ribbon or ribbon expires, please reinstall the ribbon with better performance.
2, the use of poor quality label paper, greatly reducing the transfer capacity of the ribbon, please replace the label paper test with better performance.
3, the temperature setting is low, the ribbon talk has not been completely transferred, please increase the temperature to reset.
4. The print head is dirty or its installation position is incorrect. Please use alcohol and cotton balls to clean or adjust the position of the print head.
The most important thing about the printer is the printer head. Be sure to pay attention to regular cleaning and extend the service life. Do not wait until the printing is not clear. The cleaning of the print head is also to be noted. The following describes the cleaning steps of the print head.
1. Turn off the printer power.
2. Open the printer case and lift the print head.
3. If the printer is operating in thermal transfer mode, remove the ribbon to expose the printhead.
4. Gently wipe the print head with a cotton ball containing absolute alcohol to remove dust, dirt, etc. from the top.
5. After the alcohol evaporates, the printer can be reused.
Note: During the cleaning process, remember not to scratch the print head.
Regular maintenance of the bar code printer is very important. The printer keeps the print head clean during use to ensure print quality and extend printhead life. Clean the print head, rubber roller, and ribbon sensor with alcohol each time you print a roll of labels. When replacing the print cable, first turn off the printer, computer power, and then connect the cable. When cleaning the print head, etc., turn off the power first. The print head is a precision part. It is best to ask a professional to assist in cleaning.
