How can a print head extend its life
Source: Release time:2019-05-14 Click on the quantity:2365
The print head is a delicate and expensive part of the bar code printer and is also a fragile and vulnerable device. It is a depletion product like a car. It will eventually be damaged. Only a constant attention to maintenance can extend the life of the print head.
Pre-maintenance
In order to play a better role, one print head needs to be cleaned every time a roll of ribbon or a roll of thermal paper is used up. CAUTION When cleaning the print head, remove hard objects such as rings to prevent scratching the print head, and be careful not to damage the print head with a grounded metal strip or an object with static electricity.
Can be used to soak 70% alcohol swabs, first turn off the printer power and open the print head, use a small amount of cotton in the printer's mechanical part lightly brush, or gently blow off the dust. Do not use any hard metal or abrasive tools (such as screwdrivers) to rub the print head contamination. Use a cotton swab with alcohol pressure on the print head to wipe it from scratch. Do not wipe it back and forth. Then rotate the roller and rub it while rotating. Do not reuse the cotton swab.
Causes premature print head damage
Scratches - The long-term movement of the ribbon through the print head wears off the protective layer of the ceramic coating, exposing the print head pin (spot) to eventual damage.
