As a common industrial marking equipment, although inkjet printers are designed for long-term trouble-free operation, some common failures may still occur during use, especially ink inkjet printers.

Understanding the causes and solutions of these problems is crucial to ensure the stable operation of the equipment. Below are some common printer failure types to help users find and deal with them faster.

1. Quality issues with the inkjet printer

Incomplete or fuzzy character printing: It may be that the nozzle is blocked or the ink accumulation on the nozzle is not completely cleaned. We need to stop the nozzle to clean the nozzle, and then carefully observe whether the ink droplet splitting is normal, and use the ink dot modulation value or the printing voltage setting to debug, so that the printer can quickly return to normal.

Misplacement/duplication or missing of printing content: First, we must check whether the internal parameter settings of the printer are consistent with the original, such as character width, delay value, etc., secondly, we must check whether the placement position of the nozzle has moved and observe whether the electronic eye sensor has a signal. Normal stability, whether there are any phenomena such as false triggering.

2. Ink system problems

Abnormal ink pressure or ink line deviation: For factory users, common printer failures can be solved by cleaning. Among them, we will mainly encounter problems such as filter clogging, nozzle clogging, solenoid valve clogging, ink pipeline leaks, etc. Failure situations, this problem will occur once the machine is stopped in a irregular manner or is not used for a long time.

Good ink circulation is a prerequisite for stable operation of the inkjet printer, including the inkjet pipeline and recovery pipeline. The operator must operate the inkjet printer strictly in accordance with the operating procedures and SOP, normally turn on and off the printer and clean the nozzle nozzles to ensure that the inkjet printer is clean and clean, using original ink solvents to reduce the probability of failure to a lower level.

3. Circuit control system failure

One of the two core components of the inkjet printer is the circuit system. Under normal circumstances, the circuit is still very stable, but if it is used for years or the use environment is dirty and chaotic, it will accelerate aging and cause some circuit abnormalities, such as black screen on the display screen or garbled code, button failure, inability to print words, or difficult to solve faults.

As a professional inkjet printer supplier, we will check the circuit during the regular maintenance process of the inkjet printer. On the one hand, we will ensure cleanliness, and on the other hand, we will check whether the interface wiring is normal. As users, do not repair the circuit privately to avoid occurrence of anomalies that are difficult to recover, and software updates must be done in accordance with the manufacturer's requirements.

The above three points are common faults for users of inkjet printers. If you have any questions, please leave a message and communicate.
