Maintance 0040 i can't fix this problem and i don;t know how to reset it

Did you replace the low ink cartridges? The 0040 request code is from the ink dispenser pump saying it has reached the specific number of pumps for that particular ink cartridge. Once you change out the low ink cartridge the pump will automatically reset.

Use 030, 171, 191, 004, 038, 046, 006, 012, 023 all the way to 047, 123, 14, 177, 178

Heres a link to your drivers, all OS should be supported on this page... Vf0040 also the actual apps are included to download.
hope this helps. :)
