HP OfficeJet Pro 7740 won't scan 11x17 paper

[bwilson_leasbur]

I am using a NEW HP OfficeJet Pro 7740 (my old one died recently) and have the HP Smart App installed on my Windows 11 HP computer.  There is no option to scan 11x17. I have done this in the past and I can do it on my second computer which is an older version and has the software that came with my previous 7740. I don't see anywhere that I can adjust settings to get the 11x17 option to appear on HP Smart. HP Smart has fewer options than the software that came with my old computer. This seems to be a common problem with this Officejet as it is on other help threads. Has HP fixed this problem???!!! Please help!

Hi @bwilson_leasbur,

Welcome to the HP Support Community

I understand you are facing a scan-related issue with your HP OfficeJet Pro 7740. Not to worry I will help you to get a resolution to resolve the issue.

Let's perform a power drain: 

• With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.
• Remove USB cable, if present.
• Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.
• Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord (This is important) and then plug back the power cord to the printer.
• Turn on the printer and wait till warm-up period finishes and the printer is idle

Update the printer firmware 

• Click here to download and install the latest printer firmware from your product
• Click here to know different methods of updating printer firmware.

If the issue stil persists, then let's try to do a root uninstall and reinstall of the software:

Unplug any USB cable, if any, before doing this.

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” and “/s”)

8.) Click on the "Drivers" tab

9.) Look for 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

13.) Open up the run command with the "Windows key + R" key combo

14.) Type c:/programdata and click Ok. Go to Hewlett Packard folder, remove any printer related folders & files.

15.) Restart the computer.

Once done, please download and install the software from here:

Otherwise, you can use the HP Smart App:  https://support.hp.com/in-en/document/c04675142

You may also go ahead and Download HP Scan and Capture an alternate scanning application developed for the Windows Operating system. You  may use this reference document: Using the HP Scan and Capture App

Actually I fixed the problem by downloading the 

"HP OfficeJet Pro 7740 Wide Format All-in-One Print and Scan Driver and Accessories" from the HP web site.

The HP Smart app (which was recommended by HP upon startup) would only scan a few sizes and it has no capability of doing a custom size scan so I uninstalled it.
