This is the second time I just change dampers in my Epson 3880, last time for approx. 1500 print. Also changed cap station then.
Now I have changed both “Inksupply” and pump. Counting 3500 prints now. The reason for the shift was probably that I ran empty a cartridge and got problems with that channel (LC). Air that never went away.
Choose this time to replace the entire inksupply because I found the time to change was almost the same, maybe less than changing only dampers.
I have looked at the pictures in the link below, have the service program and most importantly the service manual . When followed closely it provides all the necessary information to disassemble and, not least, restore.
Take time to read through the service manual and followed it page by page. Almost. 1 hours to dismantle cover , lid etc. so that I was left with the frame.
Disassembly of the pump took 2 hours when I chose not to follow the method in the service manual, where two screws must be loosened in the bottom of the frame and the chain on the left side must be removed. Saw a hole in the plastic so that the pump could be taken straight out. Not elegant but effective.
Before mounting, I cleaned the print head on the underside and sent " PiezoFlush " through all ink channels from the top of the head. Used a syringe with a hose
Inksupply, I spent a small hour dismantling. Mounting approx. 1 hour also when I took it very carefully.
NB - do not draw ink through the dampers before mounting on the head.
Turn on the printer.
Reset counters for Inksupply and pump in the service program.
2 Powerclean and 2 usual clean was enough to get nice nozzels .
This from January 30, 2014.

Service manual very important and in practice enough to be able to perform the job.
