According to the manual if you tried cleaning the nozzle and it didn't help, try to aligning the head.
Tried that and it failed and get an error code, which is a QR code which I followed.
According to the error code there could be 3 different causes.
Clogged nozzle
Paper size not correct
Paper slot exposed to strong light
The paper is correct, the paper slot isn't exposed to strong light, did it in a dark room.
Actually tried cleaning the head several times and once did it in the dark
So the only option is that the nozzle is clogged and I tried cleaning and deep cleaning.
What else can I do?
It should be noted that I don't print very often
