On the right hand side just reattach the metal bracket and then the control panel with the buttons and LCD to the panel and carefully connect the multi-pin ribbon cable that plugs into the control panel module. When you have flushed the dampers and cleaned the connection points you do not have to put the case back on to run and test the printer. As tools you will need a medium size thin, long shaft magnetized philips screwdriver, a small flat head screwdriver and some cue tips and ink cleaning fluid, i.e, Windex/isopropyl alcohol. If you need a new switch and damper the repair will cost $20 to $40 from Sdott Parts china. You will also have to have carefully cleaned all the connection points at the foil manifold as well. Blow air through the switch and damper to make sure the path is clear. Do a final rinse with an 80% blue Windex 20% isopropyl alcohol solution. If you work carefully you may solve the problem simply by removing and flushing out with warm water the existing switch and damper. Can you do it yourself successfully? In many cases yes, in some cases no if the seals have deteriorated beyond where cleaning will provide a repair. So to repair the printer you must remove the blockage and must clean the connections in the line to restore the seals. Wherever, pressure on the line has voided a seal upstream, most likely at the switch damper connection or at the damper foil manifold connection, but maybe at the 8 tubed ink cable into the manifold. The blockage is probably either in the black ink selection switch or in the damper above it. The print head is clean and does not need flushing. If it were you would be leaking on both channels. So where is the leak? It is not at the connection at the exit of the black ink switch into the print head. When you go back to the normally used line the leak goes away but may not entirely. Usually when there is a leak it starts when you switch to the unused black ink color, MK or PK. The black ink selection switch, in the damper assembly, sits on top of the print head. Here is the path: Ink flows from the cartridge through the line (the 8 tubed ink cable) with a connection to the foil manifold on the Switch Damper Assembly then out of the foil manifold via a connection to a damper which sits on top of the black ink selection switch via another connection.
When you switch to the unused black channel, if the line has become blocked by stale ink, the pressure on the line will press ink out through one of the connection points in the ink line and once a seal has been broken ink will continue to leak out until repaired. Epson switches between the MK and the PK black ink lines, the unused line sits idle. But first let’s understanding what we are dealing with.Įpson makes great printers but if you must not leave an ink line unused for a long period of time, it needs to be exercised. Yes, you can repair the printer yourself. Epson printers will leak the black ink from the channel you have not been using.
