How to maintain the longevity of the self-adhesive printer?

The self-adhesive barcode printer is a special printer. The printed content is generally the company's brand identity, serial number identification, packaging identification, barcode identification, envelope label, clothing tag and so on. Industrial quality, 24 hours of printing, regardless of print volume. The daily maintenance and regular maintenance of the label barcode printer is to ensure the quality and long-term performance of the barcode printer. The more frequently the barcode printer is used, the cleaner the barcode printer should be.

1. Cleaning of the print head of the self-adhesive barcode printer: To clean the print head regularly, the cleaning tool can use cotton swabs and alcohol. Turn off the power of the barcode printer. Keep the same direction when wiping (to avoid residual dirt when rubbing back and forth), turn the print head up, remove the ribbon, label paper, and use a cotton swab (or cotton cloth) dipped in the print head cleaning solution. , wipe the print head until it is clean. Then dry the printhead gently with a clean cotton swab. Keep the print head clean to get good print results, and most importantly, extend printhead life.

2, label bar code printer glue stick cleaning and maintenance: To regularly and regularly clean the bar code printer glue stick, the cleaning tool can use cotton swabs and alcohol to keep the glue stick clean, also to get good printing results, and extend the life of the print head. In printing In the process, the label paper will leave a lot of powder on the glue stick. If it is not cleaned in time, it will hurt the print head. The glue stick has been used for a long time. If it is worn or uneven, it will affect the printing and damage the print head.

3. Cleaning of the self-adhesive barcode printer roller: After cleaning the print head, clean the roller with a cotton swab (or cotton cloth) soaked with 75% alcohol. The method is to scrub the roller while rubbing it by hand, and after it is clean, dry it. The cleaning interval of the above two steps is generally three days. If the barcode printer is used frequently, it is best to clean it once a day.

4, label bar code printer drive system cleaning and chassis cleaning: Because the general label paper is self-adhesive, its glue is easy to stick to the drive shaft and channel, plus dust, directly affect the printing effect, it is necessary Clean often. Usually once a week, the method is to scrub the shaft of the transmission, the surface of the channel and the dust inside the chassis with a cotton swab (or cotton cloth) soaked in alcohol, clean and dry.

5, label bar code printer sensor cleaning to keep the sensor clean: no paper error or ribbon error will occur. The sensor includes a ribbon sensor and a label sensor. The location is described in the manual. It is usually cleaned from three months to six months by scrubbing the sensor head with a cotton swab dipped in alcohol. After cleaning, dry it.

6, label barcode printer paper guide slot cleaning: guide groove generally does not have big problems, sometimes artificial or label quality problems cause the label to stick inside the guide groove, it is also necessary to clean it in time.

7, label bar code printer temperature is generally maintained between 10-24: can not be too high, otherwise it is easy to reduce the life of the print head, pay attention to the ribbon and label matching, generally coated paper with wax-based ribbon, synthetic paper with half-tree Or a full-tree ribbon. In addition, the label paper should be kept flat, so do not make it uneven, otherwise the print head will be easily worn.

Maintenance and maintenance of the coding machine

1. Replacement of the fuse The AC power fuse that the user replaces is located below the AC power switch at the rear of the printer. The spare fuse has an electrical specification of 5Amp/250VAC and is a 3AG fast-melting fuse. Turn off the AC power switch and unplug the AC power cord before replacing the fuse. When replacing the fuse, insert the tip of the flat-blade screwdriver into the hole in the end cap of the fuse box. Gently press the end cap and turn the screwdriver counterclockwise. The end cap will be disengaged from the fuse box so that the fuse can be removed. If a new fuse is installed, follow this procedure to reverse the operation.

2, printer print head pressure adjustment Adjust the print head pressure to ensure the quality of the print. The pressure required will depend on the type of print media, the thickness, and the width of the media. Turn the pressure adjustment knob clockwise to increase the pressure; turn the pressure adjustment knob counterclockwise to decrease the pressure. If the media is too narrow to match the two tabs, reduce the pressure on the unused tabs. Generally, the pressure on the two tablets should be adjusted to be consistent.

3, daily cleaning and maintenance Note: Do not use any lubricant on this printer! Some lubricants can damage the surface coating and the mechanical parts inside the printer.

1) Cleaning of each sensor: The cleaning of the sensor (including the emission sensor, ribbon sensor, and reflection sensor) is usually three to six days. When cleaning, first pull out the paperboard and use the air blower (sucking the ball) to purge the upper and middle seams of the sensor.

2) Print head cleaning: Use industrial alcohol with a purity of 99% as a cleaning solvent. The print head should be cleaned each time a roll of ribbon is printed. This maintains print quality and extends the life of the printhead. Turn off the printer's power, turn on the printhead assembly, remove the ribbon and barcode card, and wipe the printhead (brown with metal wire) with a cotton swab (or cotton) soaked in 99% alcohol until clean. Clean the print head with a clean cotton swab.

3) Rubber roller cleaning: After cleaning the print head, clean the roller with a cotton swab (or cotton cloth) soaked in 99% alcohol. The method is: while rotating the roller by hand, scrubbing it, and after it is clean, dry it. The cleaning interval between the print head and the rubber roller is usually three days. If the printer is used frequently, it is best to do it once a day.

4) Other cleaning and maintenance of the printer: The cleaning of the drive system and the cleaning inside the cabinet are usually once a week. The method is to scrub the surface of each shaft and channel of the transmission with a cotton swab (or cotton cloth) soaked with alcohol. After cleaning, wipe it dry.

4, replace the print head Special attention:

Because static electricity can cause permanent damage to the print head, you must prepare for anti-static when replacing the print head.

1) Turn off the printer power supply and prepare the operator for anti-static work.

2) Release the print head fixing screw to separate the print head from the print head holder.

3) Unplug the print head data and power cable.

4) Take a new print head.

5) Installation data and power supply cable.

6) Place the printhead in the correct position on the printhead carriage.

7) Fasten the print head fixing screws.

8) Perform the PAUSE key start test, clean the print head according to the test conditions, 9) and adjust the appropriate print head pressure and print depth setting.

10) Turn off the power, turn the power back on, and test the machine. If the test is normal, the print head is replaced.

Replace the motherboard:

1. Turn off the printer power supply and prepare the operator for anti-static work.

2. After loosening the casing fixing screw, remove the casing.
