2.The front cover of the printer must be closed during printing to prevent dust from entering the machine or other hard objects blocking the movement of the printer car.
3.It is forbidden to plug and unplug the printer cable, which will damage the printer's print port and PC's parallel port, and even damage the PC's motherboard seriously.
4.If the printout is not very clear, you can use the printer's automatic cleaning function to clean the nozzle.
5.When the print head does not return to the original position and restart, the printer will first overprint and return to the original position, then the operation of cleaning the nozzle, so it will cause unnecessary waste of ink.
