HP Photosmart C4740: Why won't it print

Thu, 28 Dec 2017 22:37:30 -0700

Why isn't my HP Photosmart C4740 (Printer, Scanner & Copier) not printing?

It has a new black cartridge and half full color cartridge. The 1st print came out light blue/grey even though I chose black print. Now it acts like it's printing but paper comes out blank.

HP Photosmart C4740: Tear down a HP Photosmart C4740 printer

Mon, 13 Jul 2020 15:33:03 -0700

I would like to tear down an HP Smartprinter, would somebody help me? I have tried all the HP solutions, and the ones on YouTube. I get the errors “Do not recognize ink cartridge after I do the bypass it will not feed the paper. So what I think is the sensors are not working on the ink cartridges and the paper feeder.
