Bar code printer (bar code machine) FAQ collection
We have accumulated quite rich bar code printer maintenance experience in many years of bar code application. Now some generalizations are summarized as follows
Q. Installation of barcode printer carbon tape and label
A: Follow the directions shown in the figure. The dotted line is the carbon belt installation path, and the solid line is the label path. After rewinding, the waste carbon tape is not easy to peel off. Before loading, use the smooth base paper of the waste label to roll the waste carbon tape on the rewinding reel. When installing labels, adjust the paper limiter according to the label width. Pressure head spring uniform, can avoid printer label deviation. Measure the paper the first time you use the printer.
Q. Bar code printer panel control
A: PAUSE key — PAUSE and start printing; FEED key – walk a piece of paper; CANCEL key — CANCEL. When printing data to the printer, press PAUSE and then CANCEL several times until the data indicator is turned off. CALIBRATE: Label test. When a new label is installed, test the label parameters before printing the label. Method: Press PAUSE and then press CALIBRATE to measure paper. If the label is accelerated during the paper measurement, the paper measurement is correct. Note: labels can be rewound after paper testing, but carbon tape cannot be rewound.
Q. Regular maintenance of barcode printers
A: Only by keeping the print head clean during the use of the printer can the quality of the print be guaranteed and the service life of the print head be prolonged. In each roll of label printing to clean the print head, cots, carbon sensor with alcohol. When replacing the print cable, first turn off the printer and computer power supply, and then connect the cable. Note: the power should be turned off when cleaning the printing head. The printing head is a precision part, so it is best to ask a professional to help clean it.
Q. Bar code printer print head pressure adjustment
A: Print head pressure should be adjusted according to different printing media. The pressure of the printing head under normal conditions: adjust the nut to the highest position when the printing fruit is better, otherwise, there will be deformation of the rubber roller for long-term printing, resulting in wrinkling of the carbon belt and poor printing effect.
Q. All indicators of the printer are on, and the printer cannot be operated if the LCD does not display
A: If the motherboard or EPROM is damaged, contact your vendor to replace the motherboard or install the EPROM correctly.
Q. Paper cannot be measured if all printer indicators are blinking
A: If the sensor is faulty, dust the surface of the sensor, or contact your distributor to replace the sensor.
Q. There are missing lines in the printing process
A: If there is dust on the surface of the print head, or if the printer is worn out for A long time, the print head can be cleaned with alcohol or replaced.
Q. Carbon ribbons or labels are misaligned during printer printing
A: If the paper spring is uneven, or the paper limiter is not adjusted according to the width of the label, you can adjust the spring and the paper limiter to solve the problem.
Q. The printing is not clear and the quality is poor
A:
1 Temperature is too Low
2 Carbon tape label quality is poor
3 The print head is incorrectly installed
Solutions:
1 Increase the printing temperature, that is, increase the printing concentration
2 Replace the carbon tape and labels
3. Readjust the position of the print head, paying special attention to the consistency of the left and right heights
Q. Carbon bands wrinkle
A:
1 The carbon belt is not properly wrapped around the machine
2 The temperature Settings are incorrect
Print head pressure and balance Settings are not correct
4 The amount of paper to be removed is not set correctly
Solutions:
1 Correctly install the media
2 Adjust the printing temperature to meet the printing requirements as far as possible
3 Reset the minimum pressure required for printing
4 Set the correct amount of paper to be removed.
Q. Changing parameter Settings does not work
A: The parameter setting may not be correct, if confirm that the parameter setting is correct and the problem still exists, may be the motherboard problem solution: restart, factory Settings, and then parameter setting, and permanently save; If restart, factory Settings, according to the default method to use the printer, if still not, only sent to the manufacturer to replace the motherboard.
Q. It used to be normal to print labels, but since we changed to another carbon belt, labels are always printed and the paper is not normal
A: The printer has sensors to identify carbon ribbons and labels and has memory. Retest paper when changing paper and carbon tape. Solution: Zebra bar code printer as an example, press and hold down the CALIBRATE key before starting up and start up at the same time, release the CALIBRATE key after the paper is removed, then a lot of paper is out, shut down after the paper is out, and start up again to complete the paper measurement. Information is automatically recorded into the printer, the next boot does not have to measure the paper. The paper that runs out can be rewound.
Q. It is normal to print small labels, but half of large labels are always printed and the other half is empty.
A: If the printed memory is too small, or the label is too large. Some information is missing. Contact your product supplier to increase printer memory.
Q. How to print bar codes quickly
A: There are several ways to print faster. You can use one or more of them.
Use a parallel port instead of the original Zebra serial port. Serial port is easy to connect and wide to use, but its disadvantage is slow speed. For general applications, yes, but for high speed requirements of the occasion, please choose a parallel interface.
Choose high-grade printer. The maximum print speed allowed by high-end printers is much higher than that of low-end ones.
3 Set the printing speed to high speed and medium speed by default. However, the higher the speed, the worse the print.
4 Use a lower resolution print head, speed and effect can not be achieved.
