Common faults and handling methods of inkjet printers

As a precision industrial equipment, the inkjet printer will always have some failures in the production work. Many cij printers have similar faults, and the processing ideas are similar. When your inkjet printer or marking machine fails, how should you deal with it? The Zhengzhou code engineer summarized some common failure phenomena and common ways to troubleshoot, I hope it will be useful to everyone:

Old The master often said that the best repair is maintenance and maintenance. Doing this step can basically avoid many failures. Let’s learn the basic maintenance methods first:

1. Check the ink of the inkjet printer And the liquid level of the solvent must be added in time according to the procedure when the level is low.

2. Check whether the ink viscosity of the inkjet printer is normal. The ink of the inkjet printer is very important. The viscosity of the ink has a great influence on the normal use of the inkjet printer.

3. Check whether the ink of the inkjet printer has expired. As a strict chemical, the ink also has an expiration date. If the ink is past the expiration date, it should be purchased as soon as possible, otherwise the print quality cannot be guaranteed. .

4. Clean and dry the nozzle system, pay attention to the automatic cleaning procedure when the machine is turned on and off.

5. Regularly clean the fan filter of the printer

6. Regularly clean the installation and fixing devices of the printer’s electrical eye

7. Regularly check the printer Installation and fixing of printer head and electric eye

8. Regularly check the power supply and ground connection of the printer

Of course, although we usually pay attention to maintenance, we can Reduce the failure rate, and reduce the loss caused by the failure, but there may still be a failure, let’s learn the basic troubleshooting knowledge:

1. The ink of the printer is insufficient, add ink

2. Check the inkjet printer liquid level detection electrode connection

3. The cij printer additive is insufficient to add additives

4. Check whether the inkjet printer additive solenoid valve is working properly

5. fan failure or insufficient compressed air check exhaust fan or compressed air

6. temperature failure changes the working environment

7, cij printer Printer viscosity failure Check viscosity measurement pipeline

8. viscosity failure, check ink and confirm whether the viscometer solenoid valve is working normally

9. When inkjet printer starts ink line The print head cover is not closed. Close the print head cover

10, the printer high pressure fault cleaning, dry the nozzle electrode; clean the high voltage connection

11, the ink line recovery failure check and recycle the printer Whether the valve is open;

The printer fails during printing.

1. The printer has a black spot detection failure. Close the ink line, clean and dry the nozzle electrode;

2. Check the operating parameters of the inkjet printer;

3. Confirm whether the ink is invalid; perform ink update;

4. Check whether the nozzle cover is clean; check the breakpoint and adjust

5. CPU-IMP communication

6. print speed alarm to reset print speed

7. Motor speed failure, contact technical personnel< /p>

8. The printer pressure is not normal and the whole machine is cleaned. Replace the filter element and nozzle filter.

9. The printer has no fault display but cannot print and check the sensor head, etc.< /p>

10, the inkjet printing effect is poor, cleaning the nozzle

11, check whether the nozzle support is stable

12, check the distance between the nozzle and the object

13. Check whether the ink line of the printer is in the middle in the recycling tank

LEAD TECH Technology Co., Ltd. also discusses implications for both research and the practice of operations in building systems to help people succeed in both the short and long run.

A detailed plan must be developed if we hope to reach your profitability goal. Once we have a certain figure in mind, LEAD TECH Technology Co., Ltd. and our staff need to determine all the steps necessary to reach that goal and act on them.

LEAD TECH Technology Co., Ltd. who primarily serve our consumers need to consider offering their products in an date coding machine such as cij printer to take advantage of the growing interest from consumers in supporting date printing machine.

LEAD TECH Technology Co., Ltd. has developed a unique technology with many applications including expiry date printing machine.
