When the packaging machine typing is not clear or no typing problem, you can take the following measures to troubleshoot and solve
First, check the grain and ribbon
Grain arrangement and fastening:
Check whether the characters are arranged neatly and whether there are uneven or misaligned characters.
Check whether any individual characters are loose or fall off. If necessary, re-tighten or replace the characters.
Ribbon status:
Check whether the ribbon is repeatedly used to no ink, no ink ribbon will lead to unclear printing.
Check whether the color band is shifted or does not match up and down, resulting in the top of the word grain outside the color band, affecting the printing effect.
Pay attention to whether the ribbon is rolled into a strip shape, if necessary, clean up the ink stuck to the circular shaft due to the ribbon falling off.
Second, adjust the distance and tension between the ribbon and the word grain
Ribbon action distance:
Check that the distance between each movement of the ribbon is moderate. Too close may lead to unclear or no typing, and too far away will waste the ribbon.
According to the specific model and instructions of the packaging machine, adjust the ribbon action distance to the best state.
Unwinding tension:
Adjust unwinding tension Adjust the tightness of the nut. Too tight may cause the ribbon to pull, too loose is easy to alarm and affect the speed.
Third, check the air pressure and power supply
Air pressure check:
Check that the air pressure is sufficient. Insufficient air pressure may cause the grain not to be pushed into position, thus affecting the typing effect.
According to the air pressure requirements of the packaging machine, adjust the air pressure to the specified range.
Power check:
Ensure that the power supply of the packaging machine is normal and there is no power failure or voltage instability.
4. Adjust typing time and heating plate
Typing time adjustment:
Check and adjust the typing time Settings on the packaging machine's touch screen or control panel. If the setting is not clear, you can appropriately increase or decrease the typing time.
Heating plate inspection:
If the packaging machine involves sealing operation at the same time, check whether the heating plate is intact and whether the temperature setting is appropriate. Heating plate failure or insufficient temperature may also affect typing (especially for thermal transfer type printing).
5. Cleaning and maintenance
Regular cleaning:
Clean the dust, foreign matter and residual ink inside the packaging machine regularly to keep the equipment clean.
Pay special attention to cleaning the area around the grain and ribbon to avoid affecting the print quality.
Maintenance:
Carry out regular maintenance according to the maintenance manual of the packaging machine, such as replacing wearing parts, checking the wear of mechanical parts, etc.
Through the inspection and adjustment of the above steps, it is usually possible to solve the problem of unclear or no typing on the packaging machine. If the problem still exists, it is recommended to contact the packaging machine manufacturer or professional maintenance personnel for further inspection and maintenance.
