As a common industrial identification equipment, inkjet printers, although designed for long-term trouble free operation, may still experience some common malfunctions during use, especially ink inkjet printers.

Understanding the causes and solutions of these problems is crucial for ensuring the stable operation of the equipment. Below are some common types of inkjet printer failures to help users quickly identify the causes and handle them.

1. Printing quality issues with inkjet printers
Incomplete or blurry character printing: It may be due to nozzle blockage or incomplete ink cleaning of the nozzle. We need to stop the machine to clean the nozzle and carefully observe whether the ink droplet splitting is normal. We can adjust the ink dot modulation value or printing voltage setting to quickly restore the inkjet printer to normal.

Misalignment/duplication or missing printing content: Firstly, we need to check whether the internal parameter settings of the inkjet printer are consistent with the original, such as character width, delay value, etc. Secondly, we need to check whether the nozzle placement position has moved, observe whether the signal of the electric eye sensor is normal and stable, and whether there are any false triggering phenomena.

2. Ink Road System Issues
Abnormal ink pressure or ink line deviation: For factory users, common inkjet printer malfunctions can be solved by cleaning. Among them, we mainly encounter problems such as filter blockage, nozzle blockage, solenoid valve blockage, ink pipeline leakage, etc. Once the machine is stopped irregularly or not used for a long time, this problem will occur.

Good ink circulation is a prerequisite for the stable operation of the inkjet printer, including the inkjet pipeline and recycling pipeline. Operators must strictly follow the SOP to operate the inkjet printer, turn on and off normally, and clean the nozzle to ensure that the inkjet printer is clean and tidy. The use of original ink solvents reduces the probability of failure.

3. Circuit control system malfunction
One of the two core components of a inkjet printer is the circuit system. Under normal circumstances, the circuit is still very stable, but long-term use or dirty and messy environments can accelerate aging and cause some circuit abnormalities, such as black screen or garbled characters on the display screen, button failure, inability to print or difficult to solve faults.
