Question:
I’m working on my Epson L1800 DTF printer and noticed that one of the two black tubes on the capping station—specifically the one on the left—became disconnected. I tried to take the printer apart to figure out where it connects but couldn’t identify the correct spot. Can you help me figure out where this left-side tube is supposed to connect? Also, do you offer repairs for DTF printers?
Answer:
Understanding the Two Tubes on the Capping Station
Your Epson L1800 DTF printer has two black tubes connected to the capping station, and each serves a distinct purpose:
-
Left-Side Tube (Ink Suction Line):
This tube is crucial for pulling ink from the printhead during cleaning and priming. It connects directly to the waste ink pump assembly, which has two nozzle ports. If this line is disconnected, your printer won’t be able to draw ink through the head properly, leading to clogged nozzles and failed prints. -
Right-Side Tube (Air Return or Vent Line):
This tube connects to the air hole assembly, not to the pump. It does not handle ink, but instead allows air to flow during pressure equalization. If this one is disconnected, the impact is minor compared to the suction line.
Reconnecting the Left Tube
If the left suction tube came loose and you can’t locate where it attaches, here’s what to do:
-
Identify the Waste Ink Pump:
-
Open the bottom panel of the printer.
-
Locate the white plastic pump with a motor and two nozzle ports.
-
The left capping station tube should connect to one of those two ports.
-
-
Inspect the Pump Orientation:
-
One nozzle will already have a tube leading to the waste ink pad or bottle.
-
The other port is where your left capping station tube goes.
-
-
Secure the Tube:
-
Reinsert the black tube onto the free port of the waste pump.
-
Make sure it is snug and not leaking—use a clamp or zip tie if needed.
