Prints image fine but printing text results in missing lines

[neosan]

Greetings!
My printer is showing a weird behavior, where I can not print text properly. The printed page has some lines printed partially so some lines are not readable. The workaround is to make the text as image, and then print it which all the lines will print properly. The quality overall is a bit less sharp but does the job somehow!

To show you how it looks like, see the image blow, the left print is sample text printed as image, but the right, is printed as text.

I was wondering what can be the reason and if there is any fix to this! Any ideas is welcome. I don't want to throw a good printer out. It just does not makes sense.

ok I found the issue. the black cartridge was faulty! so just changing the black cartridge fixed the issue.
