XXL disaster for these "XL cartridges"

I bought 2 sets of 10 x XL ink cartridges which are to be T1281 to T1284 supposedly compatible with Epson, for a friend for the Epson Stylus SX 435 W. After the large black cartridge was empty, we initially only replaced these. Result: Cartridge can not be recognized by the printer. After replacement of all cartridges. Result: No cartridge is detected. Old original cartridges reinstated. Result: color cartridges and small black are detected, big black is not recognized. Multiple playthrough this procedure with exact observance of the requests included in the cartridge special instructions (including compl. Neuaufspielen the original printer driver and blocking the update function) always led to the same result. The contact with the service from the supplier via e-mail did not lead to different results.
Result: After 3 days of fruitless Rumlaborieren of less than three-year-old printer with the brand new 2 x 10 landed XL cartridges in the recycling center and it was a new printer bought (from the competition). An expensive and Dime. Stay away from these cartridges !!!!!!
Should also be noted that I have on my various Canon printers for many years exclusively cheap replica cartridges, but used by other suppliers, without it ever came to problems. So it can not be due to lack of experience.
