I have a Canon MG3650S printer, and I took it out after not using it for a while. I put in a new ink cartridge and tried printing, however I noticed it would miss gray lines and borders, which I assume were gray. This only happens when I print double sided and the printer prints normally when its single sided.
Here's one of the PDFs I tried printing: https://filestore.aqa.org.uk/sample-papers-and-mark-schemes/2022/june/AQA-8464C1H-QP-JUN22.PDF
I only have black ink inside of the printer, however I had to put an empty colour cartridge inside, else it wouldn't let me print.
If somebody knows how to fix this, please do let me know.
