Windows 10: HP OfficeJet 4650 stopped printing in colour and automatic duplex printing

I am having 2 issues which I suspect are both connected......


1) Printer stopped printing in colour.

- I have several times uninstalled and reinstalled printer and print drivers, both from HP website and CD.

- Printer is able to print in colour - I can print proper test page and copy in colour - it is NOT a colour cartridge or printer hardware issue.

- in Programs, only the Basic Device Software is showing up - not full features which is what I've been downloading

- in printer properties, advanced - there is NO option coming up "print in greyscale" to turn off, so don't suggest this step

- this has happened before and uninstalling and reinstalling with CD worked....this time, not so much.


**I URGENTLY need to print in colour .....very upset about this!


2) Printer has stopped automatically duplex printing

- this happened before and uninstalling and reinstalling fixed it

- only shows options for manual duplex printing where you have to take the sheets and reinsert them

- I've gone into printer properties, device settings and Automatic Duplexing unit shows "Not Installed". I can get it to show "Installed" by Updating in Automatic Configuration but when I exit and go back in, it is always back to "not installed".

- Automatic duplex printing was one of the main reasons I chose this printer.


Any help with either of these issues appreciated, but colour issue is very URGENT!


Thank you

:)

 

Wireless Printer Will Not Duplex Print


I use 2 HP printers, one is the Officejet Pro 8600 and the other is the LaserJet Pro MFP M26nw. The Officejet will do automatic duplex printing while the LaserJet won't [manual only]. The key seems to be the ADF/Automatic Document Feeder of the Officejet which the Laserjet doesn't have. Looks like your Envy 4520 doesn't have that either.

A note: both of my printers are connected via Ethernet cable to my Router and any Wired or Wireless machine can print to them when the software is installed as a Networked printer. Wife went to make copies on the Officejet the other day, saw a message for an update, did it and now we have ePrint set up on it, has it's own E-Mail Address and should be able to print from anything with Internet service.

Then why does it work on the Dell Desktop but not on the HP Laptop?

 

Windows 10 HP Officejet Pro 8620 Will not print


Thank you for posting this. I tried all the listed steps and still not able to print EXCEPT when I ran the HP Print and Scan Doctor; at the conclusion of the scan, the app prompts me to print a test page from within the Scan Doctor and it is successful. I recall the 8620 being able to do this as well, however.
