Customer Question

I refilled my eco tank printer with all of the colors. I have never had a problem before but it's printing as if there is no black ink. I have run the cleaning print head nozzle numerous times.
JA: What's the exact make and model of your printer, and can you guesstimate how old it is?
Customer: It's less than a year old. I bought it in the summer of 2016 It's ET-4550
JA: What kind of computer are you printing from (Mac or PC)? What Operating System (OS) are you running?
Customer: Mac air running on Mac OS Sierra version 10.12.4
JA: How long has this been an issue? What happened right before this popped up?
Customer: It just started. My black ink and yellow were low. I refilled it as I have before. Then when I went to print, it came out almost blank. I couldn't even align because I couldn't see the choices
JA: Is there anything else important you think the Printer Technician should know?

Okay...thank you. So what should I do?
Expert:  Joel Kalman replied 4 months ago.

I recommend doing a manual cleaning of the printhead using a cleaning kit. The kit consists of a bottle of cleaning solution, a syringe, and a short length of plastic tubing. There is an excellent video which shows exactly ho to do it.
