WHY WON'T IT PRINT? - Epson Xp-400 Small In One

How old is your cartridge,it could need to be changed.

mi sumadora, de repente se queda en E y no me deja seguir sumando cantidades que solucion tiene esto

If it copies ok, then the issue is either the way it is cabled to computer or the print driver software settings on pc.... How is it connected via USB? Check port and correct driver is in windows/control panel/printers. Reinstall.

You need to call Brother at 1-877-brother and tell them your mfc is "missing black". They will tell you where to take it to get the print head replaced under Brothers' warranty. This is a VERY common problem and Brother will cover the cost to repair it.

Your machine needs to be serviced.
replace the cartridge with the original one.
it can not print if one cartridge is missing or not original.

Any error messages on the printer digital screen or the desktop? I take it the "The ink is fine" means that there is ink in the cartridges!

Try a test print via the Control Panel> Printers and Faxes> properties > Print test page.

how can we print a booklet on this printer

check the print head belt.......belt that moves the cartridge from left to rite
check to see if all the teething grooves on the belt is intact...and that its all there..if this belt slips a teeth it wont print in a straight line....

remove print head assembly. clean off.
