Solutions to Common Faults of Needle Printer

First, the printed words are incomplete or unclear or the handwriting is weak.

1. The printing ribbon has been used for too long. You can change it to a new one.

2. The needle of the print head is broken and the driving circuit is faulty. The spacing between the print head and the print roller can be adjusted first. If it is still abnormal, please contact a professional for maintenance.

Second, the movement of the print head is blocked, and it stops ringing or vibrating in place.

1, the print head guide rail is dry because it has not slipped for a long time, and the print head will get stuck when moving. You can wipe the dust off the printing guide with clean paper or cloth, and then move the print head back and forth by hand to see if it can move normally.

2. It may be that the ribbon is stuck, which makes the print head unable to move. At this time, the machine should be turned off immediately for inspection.

Third, the printer doesn't take paper.

First, confirm whether the printing paper is correctly installed on the chain feeder or correctly placed on the paper feeding platform; If everything is all right, please check whether the printing mode is the selected single page mode or continuous mode.

Fourth, the printer goes blank paper.

The reason may be that the ribbon is dry or not stuck in the right position, or the value set by the paper thickness adjustment lever is too large, which affects the contact between the print head and the platen. The position of plain paper should be adjusted to "1".

Most of them are caused by poor connection between the parallel port of the printer and the host computer. When encountering such faults, please plug the printer and the host tightly. It may also be a driver installation error, please choose the correct driver installation. It is also possible that the connecting cable between the printer and the host is plugged and unplugged, resulting in the damage of the printer motherboard.

1. Check whether the printer is online. Under normal circumstances, the online light on the printer panel should always be on. If the indicator light is not on, the connection is not normal. Please check whether the printer power supply is turned on, the printer power switch is turned on, the printer cable is connected correctly, and the paper is loaded correctly.

2. Check whether this printer is set as the default printer. Click "Start/Settings/Printer" to see if there is a small black tick on the icon of the printer currently in use.
