Epson XP-422 missing lines when printing

[Brian McCracken]

Hi all, new to the forum

Have a problem with my Epson XP-422.

It's missing lines across the page when printing in B/W

Tried a photo copy in colour and it's ok, missing about 2mm every 20mm or so when photo copy in B/W?

Tried usual cleaning and replacing ink cartridge but still same, any ideas?

Sounds like a blocked black nozzle in the print head...
It is possible to get cleaning fluids to clear the problem, but it's a fiddly task that takes ages......
