1. Make sure the printer has a stable working platform and do not place anything on the top of the printer.
2. The front cover of the printer must be closed when printing to prevent dust from entering the machine or other hard objects impeding the movement of the printer carriage.
3. It is forbidden to plug or unplug the printer cable while the power is on. This will damage the printer's print port and the PC's parallel port. In severe cases, it may even damage the PC's motherboard.
4. If the printout is not clear, you can use the printer's automatic cleaning function to clean the nozzle.
5. When the print head is restarted without returning to the initial position, the printer will first return the print head to the initial position, and then clean the nozzle, which will cause unnecessary waste of ink. The way to solve this problem is to often Wipe off the dust on the guide shaft and lubricate the guide shaft. Use lubricating oil with good fluidity, such as sewing machine oil, to ensure the cleanliness of the surrounding environment.
