1. Quality problem of ink cartridge or toner. If the quality of the ink cartridge or toner is poor or exhausted, the printed handwriting will be blurred or unrecognizable. At this point, the ink cartridge or toner needs to be replaced.
2. The problem of printing paper. If you use low-quality paper, even if the printer is of good quality and well adjusted, the printed content is still blurred and unrecognizable.
3. The print quality setting is incorrect. Sometimes the printer quality setting is incorrect, or the printing quality setting is too low, which will also cause the printed content to be unclear. It is recommended to adjust the quality setting of the printer.
4. There is something wrong with the print head or nozzle. If the print head or nozzle is damaged, blocked or not properly aligned, the printer will not be able to output clear handwriting. At this time, it is necessary to clean or repair the print head or nozzle.
5. Data transmission error. If there is an error in data transmission, the printer may also output incorrect or unclear content. It is recommended to check whether the data transmission line and connection port are loose or damaged.
Generally speaking, maintaining the printer, selecting high-quality ink cartridges and paper, setting appropriate quality, and checking or cleaning the print head or nozzle are all important steps to keep the printer's clear output. In addition, check the connecting cable of the printer regularly to ensure the normal data transmission.
