A good functioning pump assy contains a pump head, a rotor and a motor. Please kindly refer to the below picture. Motor seldom goes wrong while pump head does all the grinding and easily fail, in this case we could replace a new pump head or fix it with new gear kit.
There are many causes that can lead to ink oozing from the pump, the most often case is the screws got loosen, but many other possibilities exist.
When you come across a leaking pump, please send us pictures or video about the situation, we will take a look and provide guidance to the next move.
For instance, my customer Jack feedbacks that his pump got a leakage problem, then he dismentals the pump assy and finds out that there are cracks in the rotor. This contributes one more new cause for a leaking pump. We are sorry about the trouble caused to Jack and send a new rotor to fix his pump asap.
If there is after sales problem, don’t worry, message us and let’s fix it together.
