 Hi, this is Kevin. Today, we're going to troubleshoot problem P02 and E02-03 once you have a continuous ink system. The reason is the cable is too short, so it can reach the left side of the printer if you have a P02 error. Let's say this is a perfect printer, so I'm going to move the cable to the right, make it shorter on the left. And you'll see what happens. OK, that's P02 error. And I believe P03 is you can reach the right side of the printer. It depends on where your ink tank is. Maybe you do not have a long enough cable. In that case, you move the tank to the front a little bit, so you gave a more tube to work with. If a quantitative person, you can take the cartridge out, and then you measure 24 centimeters from the base of this clip. And then you mark it with a tape or something. So here's 24. Then you mark it with a tape. And that marker should be about the center of the printer. There we are a little bit short here, so we're going to move the tube to the center of the printer. So this should solve the P02, P02, P03 errors. If you get error E02 or E03, that's because this cable is too tight, and that the door cannot be properly closed. And if you look at the door on the left side, there's a poker. That's the door trigger. If that trigger cannot be fully inserted, the door is not properly closed. So still, you need to give a bit longer cable, so we can securely close the door. I hope this solved your problems. Happy printing. If you come here, you don't have a CS, and those errors is because your carriage cannot move to the particular position, then you can think of what happened and then troubleshoot it.
