Then she found a quiet corner of the internet—a Windows help forum with a post from 2019, marked . A user named ScanGuru had written: “I’ve done this on three different Windows 10 64-bit machines. HP never made an official driver, but the Windows 7 64-bit driver works perfectly if you install it manually. Here’s how:” Mrs. Chen followed the steps carefully, like a recipe for her famous apple pie. Step 1: Download the official HP ScanJet 3770 driver for Windows 7 64-bit. She went directly to HP’s support site, entered “ScanJet 3770,” and chose Windows 7 64-bit. The file was called SJ3770_64bit.exe . No sketchy sites. No pop-ups.
She scrolled through the list, found as the manufacturer, and looked for “HP ScanJet 3770.” It wasn’t there. But next to it, she saw “HP ScanJet 3970” – the model above hers. Close enough? She clicked it anyway, ignoring the warning about the driver possibly not matching.
The first few results were sketchy driver download sites full of blinking buttons and fake “Start Scan” ads. She almost clicked one, but remembered her grandson’s warning: “Never download drivers from strange pop-up sites, Grandma.”
