Epson stylus c40ux the ink won't print in black or color

Since 2005 Epson and all other inkjet manufacturers use a little of the colors to print black. so ,no,you will not be able to print just clack.
Even color laser printers use the colors to print black.The exceptions since 2009 have been the Canon color lasers and the HP color lasers units they provide print engine for.

There is a place in the printer driver (epson part) that hays checkboxes for "color" and "Black & White". If you are trying to do this becasue you are out of one or more of the color inks, and can't print- you still won't be able to until you replace the empty ink(s), even though you told it black & White

Press the maintenance button. The print head moves to the black or color ink cartridge replacement position, the power light begins to flash, and the error light begins to flash or remains on. When both cartridges are out of ink, the print head moves to the black ink cartridge replacement position first. After replacing the black cartridge, press the maintenance button again to switch to the color cartridge replacement position.

See status monitor? It's service required? Find SSC utility to reset waste ink counter. Try to find indoreset.blogspot.com. Or contact me for the reseter and instruction detail.

If you have carried out 4 to 5 head cleans, waited about 8 hours and done another 3 or head cleans doing nozzle checks after each clean (as recommended by the manual) and there is still no improvement then you will need a third party head cleaning solution such as this one:

Other makes & brands are available just google "inkjet head cleaning solution" Hope this helps.
