DeutschThe HP OfficeJet 4650 was released in 2015. HP Smart still lists it as supported. The driver installer still fails on a significant share of Windows 11 machines. These three facts coexist, and none of them are in HP’s documentation.
What the OfficeJet 4650 error message says — “Driver not available” — is technically accurate but tells you nothing about the actual problem. The driver exists. HP published it. The issue is that the installer that delivers the driver was built against Windows 10’s signing behavior, and Windows 11’s stricter policy blocks it mid-installation, often without a visible error. You get a success screen, then a printer that doesn’t print.
This article covers what’s actually happening and the sequence that fixes it.
The HP Smart Trap
When you go to support.hp.com for the OfficeJet 4650, the primary recommendation is HP Smart — the universal app HP uses for all current printers. HP Smart will install without issue. It will show your printer as connected. And then the printer may still not appear in Settings → Printers & Scanners.
This happens because HP Smart and the underlying print driver are two separate layers. HP Smart is the interface. The driver is what Windows actually uses to route print jobs. On Windows 11, the driver component that HP Smart tries to install in the background — a PCL-based driver package — sometimes fails to register correctly in Windows’ print spooler.
HP Smart doesn’t surface this failure. It shows “Printer added” regardless.
To check whether your driver installation actually succeeded: open Settings → Bluetooth & devices → Printers & scanners. If HP OfficeJet 4650 appears there as an installed printer with an associated port, the driver is installed. If it doesn’t appear — or if it appears with a “Driver unavailable” status — the underlying driver failed.
Why the Scan Component Breaks Separately
The OfficeJet 4650 is an all-in-one: it prints and scans. These two functions use different drivers.
The print driver handles the print queue. The scan driver — which implements TWAIN and WIA interfaces — handles everything that shows up in Windows Scan, the HP Scan app, and third-party scanning software. They’re installed by the same package, but they register as separate devices in Windows.
Windows 11’s driver signing requirements changed in 22H2. The scan component of the OfficeJet 4650 driver package uses an older signing certificate that Windows 11 22H2 treats differently than Windows 10 treated it. On some machines, this causes the scan driver to fail installation while the print driver succeeds. The result: printing works, the scanner never appears anywhere.
This is the most common OfficeJet 4650 complaint on Windows 11, and HP’s standard answer — “reinstall HP Smart” — doesn’t address it because the problem is in the driver package, not the app.
The Fix Sequence That Works
Step 1: Full removal first. Partial installations leave broken registry entries that block clean reinstalls. Before anything else:
- Uninstall HP Smart from Settings → Apps.
- Uninstall any HP printer software listed in Apps (HP OfficeJet 4650, HP Print and Scan Doctor, HP Solution Center if present).
- Open Device Manager, expand Printers, right-click any HP OfficeJet 4650 entry → Uninstall device → check “Delete the driver software for this device.”
- Restart the PC.
Step 2: Download the full feature software package. Not the basic driver. Not HP Smart. The full feature software for Windows 10 64-bit, which HP still lists for the 4650. The filename typically starts with OJ4650_Full_WebPack. It’s around 200 MB. The basic driver is around 30 MB — if the file you downloaded is small, you got the wrong one.
Step 3: Run the installer in compatibility mode. Right-click the installer → Properties → Compatibility tab → check “Run this program in compatibility mode for” → select Windows 10. Then run it as administrator.
This bypasses the signing validation behavior that causes silent failures on Windows 11 22H2+.
Step 4: After installation, verify both components.
- Check Printers & Scanners in Settings — the OfficeJet 4650 should appear.
- Open Windows Scan (or the HP Scan app) and check whether the scanner is listed as a source device.
- If the printer appears but the scanner doesn’t, the scan driver installed but didn’t register. Try running HP Print and Scan Doctor — it’s a separate HP diagnostic tool that can re-register the scan component without a full reinstall.
If the Compatibility Mode Route Fails
On some Windows 11 machines — particularly those that upgraded from Windows 10 rather than installing Windows 11 clean — the HP driver installer fails even in compatibility mode. This usually comes down to residual registry entries from a previous HP installation that the uninstall process didn’t fully clean.
At this point, the options are:
- Use a registry cleaner targeted at HP printer entries (the HP-specific ones, not a generic sweeper — this requires manual work).
- Or use a tool that bypasses the HP installer entirely and installs the driver package directly.
PrintPro Driver Pro takes the second approach. It doesn’t run HP’s installer; it extracts and installs the driver files directly, which sidesteps the signing and compatibility layer issues that cause HP’s own installer to fail. For the OfficeJet 4650 specifically, it installs both the print and scan drivers simultaneously — one operation, both components.
