Paper size wont change in dual tray HP 8600 Pro Printer

[rockstir]

I have a Officejet 8600 Pro printer with two trays. I print 4x6  mailing labels or #10 envelopes from tray 1 & tray 2  for letters for years. This past few weeks I am unable to print the labels even though i change page settings to 4x6. it keeps showing a 8x11 page. i looked for paper stuck on inside i pulled out a sheet that coiled up on left side and thought that was the problem. that didnt solve it. i went into settings and kept changing the settings, even though i change the settings they don't seen to stay applied even after applying. Did anybody else have this problem

@rockstir, Welcome to HP Support Community!

Follow the steps below to isolate and resolve the issue-

Use HP Print and Scan Doctor

Download HP Print and Scan Doctor and run the program. It will automatically diagnose and fix any printer connectivity issues. 

For more information, go to https://support.hp.com/us-en/topic/printscandoctor

Update the printer firmware

Download available firmware updates from the HP website

With the printer on and connected to the computer, go to HP Customer Support - Software and Driver Downloads, and then identify your printer. Look for and install any available firmware updates. Refer to the document HP Printers - Updating or Upgrading Printer Firmware

If the issue persists, I recommend you delete the driver and root level and retry, follow the steps below: 

1) In Windows, search for and open Programs and features 

2) Select your HP Printer 

3) Select Uninstall 

4) In Windows, search for and open Devices and printers 

5) In the Devices and Printers windows look for your HP printer. If you see it listed right-click on it and choose ‘Delete’ or ‘Remove Device’ 

6) Open up the run command with the “Windows key + R” key combo. 

7) Type printui.exe /s and click Ok. (Note: there is a space in between “printui.exe”

8). Click on the “Drivers” tab 

9) Look for the HP Printer driver. If you see it Click on it and click Remove at the bottom 

10) Select Ok 

11) Select Apply and Ok on the Print Server Properties windows 

12) Close Devices and Printers.

Use this link to download and install the new driver. Configure the printer.

Also, if the printer is wireless configured, add a TCP/IP port.

1. Print a Network Configuration Report from the Printer Settings or Wireless menu.
2. Right-click your printer, select Printer Properties, click the Ports tab and then click Add Port.
3. Select Standard TCP/IP Port, and then click New Port.
4. Follow the instructions to add a new port using the information listed on the Network Configuration Report.
5. Try printing.
