Epson Customer recommended print cartridges cleaning - until the cartridges are empty.

Have unpacked the printer and taken to the (very bad) instructions in operation.
After inserting the cartridges to install the drivers and software, which I have previously downloaded currently in EPSON came.
Amazingly, find the upgrade tool even newer drivers and software versions.
Everything installed and printed the first page.
---- In the expression is only every fourth row recognizable ---- So carry out the nozzle cleaning. ---- Next surprise: EPSON cleans all nozzles! ---- This is significantly better in CANON, since the cartridge used for text printing can be cleaned separately.
---- After the first cleaning: no improvement discernible. ---- So again Clean (All cartridges have already lost a third of its filling level!) ---- Result: minimum detectable strips in the nozzle check printout ---- So Technical Support Contact: In the live chat I only meant to indicate even if I Original cartridges have used. Then quite a few questions regarding the connection etc. ---- Finally, the instructions for POWER-nozzle cleaning ---- Should I get up to four times to carry out ---- I then made ---- SUCCESS: No improvement in the expression, for But the note of the printer that the print cartridges are almost empty? ---- The support recommended even to buy new print cartridges, because it could be that supplied more than six months are and therefore cause problems ---- Sure, it is cleaning so often recommended, since one then an original cartridge set for 80, - can sell.
CONCLUSION:
It may be that the printer is a "mon model" was.
I can not judge the print quality because the printer was not working.
The support service of EPSON is helpful - in increasing the own revenues.
I've packed up and sent back to the printer.
