Hmmm... I don't own any of the newer Epson printers, so I am not
familiar with how to open the case. They usually has some sort of
locking tabs that need to be accessed from the bottom with a long
bladed screw driver to release them.
However, the cleaning station I am speaking of is where the heads sit
after the printer shuts down or when they are being cleaned. If you can
get the head carriage moved to the left side you should have access to
this. One way to do that is to start the printer printing and when the
head is over near the left side, unplug the printer from the wall socket
(mains if in the UK). You should then be able, with a good light, be
able to see the cleaning station area, and determine if it is filled
with ink. It should not be. If it is, the purge pump or hoses may be
clogged of damaged. Try dripping some ammoniated window cleaner into
the cleaning station are, and then allow it to sit for several hours,
and then plug the printer back in and turn it on, allowing it to go
through a cleaning cycle, and see if that helps.
One other thought. If a puddle of ink has formed in the head carriage
area (where the cartridges go) it can slowly drip down, even if you have
a new properly sealing cartridge in now.
I would consider removing all the cartridges and with a flashlight, look
at the lower area of the cartridge compartment (carriage) and see if
there seems to be ink down there. If so, clean it out with cotton swabs
and water or ammoniated window cleaner until it is clean. Then
reinstall the cartridges, clean the paper transport by running some
water color paper sprayed on one side with the same cleaner. Send it
through the printer several times to clean any rollers than were
contaminated.
I hope some of these suggestions prove helpful.
