1350 "check print cartridge" light keeps blinking

[DeptofMeteors]

I just got this printer, so I don't know a great deal about it, but the "check print cartridge" light keeps blinking. I've followed the troubleshooting guide, which says:

• Access door might be open (it isn't)
• Cartridge might be missing or improperly installed (they seem seated fine)
• Tape on cartridge (it doesn't have any)
• Might be a problem w/the cartridge (unfalsifiable)

Oddly enough, when I cycled the power on the printer, it printed a test pattern, w/a fair bit of banding on it, but the light still blinks. One idea I had is that the cartridges aren't in their right bays. Is that possible? Are they idiot-proof?

@DeptofMeteors,

Welcome to the HP Support Community. 

I'd like to help!

I understand you are facing print quality issues.

To assist  better-

1) Does the copy print out the same way? 

2) What's the application you are trying to print from? Have you tried printing from a different application or devices? 

While you respond to that, let's print a Print Quality Diagnostic page -Post the Print Quality Diagnostic page here so we can help you further. 

You may also refer to this document with steps to fix " Print Quality Issues" issue applicable for your printer -  Print Quality Issues

 Also, try updating the printer's firmware - HP Printers - Updating or Upgrading Printer Firmware 

Hope this helps! Keep me posted.
