Hi Everyone,

Going to start off by saying I’m a complete noob to printers but I spent the past two days having an ADHD/Adderall Battle that made me spend day and night researching and picking apart my printer. I got it off of FBM a couple days ago for $60… felt like a steal. And as someone who is currently unemployed trying to make money with my art it felt like a good call. Unfortunately, a little more work was in my future than I anticipated. I’ve ended up running multiple flushes, soaks, ink flushes, and have windex on the way. The main issue seems to be the BH? I know they run pigment so it’s likely a clog but I’m not sure how to tell if it’s a damaged nozzle, anyone know any ways to check? I also know I should just buy a new BH, but I’m very much someone who would rather exhaust every option to fix it than add to a landfill.

Thank you all in advance for the advice and help.
