Teach You how to Extend the Service Life of the Print Head of Bar Code Printer

The most valuable part of a bar code printer is the print head. The print head is very important but also the most vulnerable. Most people want to know how long the general service life of the print head of a bar code printer is. For this problem, it can't be calculated by time, but by the print length. However, everyone should understand that anything will wear out after a long time of use, which still depends on your maintenance efforts and attention. Now let's talk about the problems of the print head of bar code printer and some preventive measures.

How long is the service life of the print head of a bar code printer?

The service life of the print head of the bar code printer is not calculated by the length of time, but by the print length, which is a bit like the mileage of a car. Generally, the normal service life of the meter is about 30km~50km.

What is the reason for the broken needle in the print head of the bar code printer?

The bar code print head is composed of a row of hot pressing needles, and the higher the density of the print head, the thinner the hot pressing needles. Therefore, it is easy to see the phenomenon of the broken needle of the print head. If you find a straight and fixed blank line from top to bottom on the printed label, it means that the needle of the print head is broken, and the broken needle of the print head cannot be repaired, but can only be replaced, and the price is not cheap, so it is very important to take good care of it.

What are the main factors that cause broken needles in printing?

1. The poor label surface contains an uneven phenomenon, which is also one of the main reasons for needle breakage.

2. The dust on the surface of the paper scraped the thin needle like a big stone.

3. Due to the use of inferior carbon tapes and labels, the temperature of the printing head must be increased to print clearly, but the high temperature is also the reason why it is easy to break the needle and shorten the service life of the printing head.

4. The label that fell on the ground is covered with dust but rolled back for use.

5. The used width of the carbon tape should be wider than the label because the edge of the label is very sharp; You can cut not only your hands but also your letterheads, so don't use a size narrower than the label to save carbon tape; At that time, the cost of changing the prefix is much more than that saved.

6. The drum under the print head is not clean; many protruding hard rubber blocks cause the road to limp.

How to maintain the print head of the bar code printer?

1. Try to use labels and carbon tapes provided by barcode printer agents Because at least they have a better understanding of the characteristics of printers and can appreciate the importance and cost of print heads.

2. Do not use the label that has fallen on the ground and is covered with dust or is not packaged on the machine.

3. Do not arbitrarily adjust the temperature of the letterhead to print a little black, as long as it is clear and printable.

4. The horizontal and vertical pressure of the bar code print head should be accurate so as not to cause uneven burden and needle breakage.

5. Wipe the barcode printer head with a cotton swab dipped in alcohol every three rolls of carbon tape, wipe the drum with a clean cloth dipped in oil, and then use a brush to drive away the dust in the machine.
