1. Q:What are the advantages of Codewel compatible print heads?
A: 1) Ultra-high quality, all accessories are 100% brand new, made in China.
2) Adopt thin film technology and independently develop internal circuit board design.
3) Provide the same warranty as the original print head.
4) With a 20-year experience R&D team in the first-class Rohm company, the quality of the print head can be controlled.
2. Q:What should I do if the printing density is uneven?
A:1) Check whether the print head pressure is balanced and adjust the rubber roller pressure.
2) Clean the surface of the print head.
3) Confirm that the ribbon matches the media (such as wax-based, mixed-based or resin-based carbon ribbon).
3. Q: How often do you need to clean the print head?
A: 1) Regular use: Clean after each roll of ribbon is replaced or at the end of each day's work.
2) High-load use: clean every 2-3 hours.
3) Clean immediately when you find that the print quality has deteriorated.
4. Q: How to clean the print head correctly?
A: 1) Use a special cleaning pen or non-woven cloth to dip in a small amount of isopropyl alcohol (do not use water or alcohol).
2) Gently wipe the surface of the print head in the same direction to avoid scratches.
After cleaning, wait for it to dry completely before turning on the machine.
5. Q: How long is the life of the print head?
A: Depending on the frequency of use, media type and maintenance, it is generally 30-50 km in length, and some industrial print heads can print up to 100 km in length.
6. Q: Can the print head be repaired?
A: The print head is a precision electronic component and is usually not repairable. It is recommended to replace it directly.
7. Q: What is the DPI of the print head? How to choose DPI?
A: DPI is resolution: measured in DPI (dots per inch), common ones are 203dpi, 300dpi, 600dpi, etc. The higher the resolution, the finer the print.
203dpi: basic logistics labels, thick barcodes (such as shipping labels).
300dpi: fine barcodes (such as medical labels), small text or simple graphics.
600dpi: high-precision images, micro text (such as electronic component labels, anti-counterfeiting labels).
