HP Envy 7640 Driver, Network Setup Failures, Blank Scans, Paper Feed Problems, and Print Quality Issues

HP Envy 7640 Driver, Network Setup Failures, Blank Scans, Paper Feed Problems, and Print Quality Issues

HP Envy 7640 problems often appear after the printer has been moved, reset, updated, or reinstalled. In the reported cases, the printer could show that it was connected to Wi-Fi on its own display while Windows still failed to complete setup. Other cases involved HP Smart scan behavior changing after an update, paper feed problems after a cartridge change, blank printed pages, incorrect colors, and a door-open message after physical impact.

These problems should not all be treated as driver failures. A Windows network-profile error points toward device discovery or network setup. Blank ADF scans after an HP Smart update point toward software behavior rather than a feeder failure. A buzzing sound during paper feed points toward a tray or paper-path engagement issue. A door-open message after the printer was knocked points toward a physical cover or sensor problem.

Problem: HP Envy 7640 will not reconnect after being moved

What users observed: After moving the HP Envy 7640 to another location in the room, the computer could no longer connect to it. The printer showed that it was connected to the wireless network, but the desktop setup failed with an Unsuccessful Network Installation message. The failure appeared between the router and printer during setup, even though the printer itself looked connected on its display.

What was tried: Users tried a semi-reset of printer settings, completely uninstalled and reinstalled the driver, and repeated the setup process. HP support also suggested that the printer’s age meant drivers were no longer current and recommended replacing the device.

How this played out: The case behaved like a mismatch between the printer’s own Wi-Fi connection state and Windows network recognition. The printer could be connected locally, while Windows still failed to build the correct network printer path. In similar cases, the useful direction was resetting the printer’s network configuration and rebuilding the Windows connection from a clean state rather than treating the printer as physically dead.

Problem: Windows says it does not have a network profile for the HP Envy 7640

What users observed: After removing the printer from Windows and trying to add it again, Windows displayed a message saying it did not have a network profile for the device. The printer still showed that it was connected to Wi-Fi, but Windows either detected it inconsistently or rejected the setup before the printer could be added properly.

What was tried: Users tried full reinstall workflows and repeated add-printer attempts. The printer remained visible at times, but Windows would not complete the setup.

How this played out: The issue pointed more toward Windows discovery and network-profile handling than a failed Wi-Fi radio inside the printer. The printer could be on the network while Windows still lacked a usable profile for it. Rebuilding the printer’s network setup and then adding it back to Windows from a clean state was the more relevant path.

Problem: HP Envy 7640 scans blank pages from the document feeder after HP Smart update

What users observed: Scanning through the automatic document feeder produced blank pages when the scan was started from HP Smart on a PC. The flatbed glass still scanned normally. The document feeder also worked from a mobile phone app. The issue appeared immediately after an HP Smart update.

What was tried: Users ran HP Print and Scan Doctor, which reported no problems. They also tried reinstalling software and installing full Windows drivers instead of relying only on HP Smart.

How this played out: The pattern did not fit a broken document feeder. The feeder worked in another scan path, and the flatbed worked normally. Later reports indicated that an HP update resolved the blank ADF scan behavior, which made the issue look like an HP Smart software regression rather than a hardware defect.

Problem: HP Envy 7640 will not feed paper and makes a buzzing sound after cartridge replacement

What users observed: After replacing a black cartridge and completing alignment, the HP Envy 7640 stopped feeding paper. During print attempts, it made a low buzzing sound instead of pulling the sheet normally.

What was tried: Users tried multiple cartridge swaps and restarted the printer. In one reported case, the user removed the entire paper tray, reseated components around the photo tray area, and reinstalled the tray.

How this played out: The paper-feed failure did not behave like a cartridge problem, even though it appeared after a cartridge change. Reseating the tray mechanism restored feeding in at least one case, which pointed toward a mechanical engagement issue in the tray or paper path rather than the new ink cartridge itself.

Problem: HP Envy 7640 prints blank pages even though ink is present

What users observed: Output degraded from faded lines to fully blank pages. The cartridges showed ink, and the ink could mark paper manually, but the printer still produced blank output after normal print attempts.

What was tried: Users cleaned cartridge electrical contacts and ran cleaning and alignment routines. Replacement cartridges were considered when cleaning did not restore output. Some cases also showed a split where PC printing failed while mobile printing worked.

How this played out: When cleaning and alignment did not restore output, the problem stayed close to cartridge, printhead, or ink-delivery behavior. The PC-versus-mobile split also showed that software or driver path could contribute in some cases, but blank pages with ink present were not solved by assuming the printer was only offline or missing a driver.

Problem: HP Envy 7640 shows Door Open after being knocked or dropped

What users observed: After physical impact dislodged hinge components, the HP Envy 7640 displayed a persistent door-open message and would not print. The printer continued to behave as if a cover was open even when the user tried to close it.

What was tried: Users visually inspected the hinges and covers. The broken or displaced hinge parts were linked to the persistent door-open state.

How this played out: The issue pointed toward a cover sensor not being physically actuated because the hinge or cover alignment had shifted. The printer was not misreading the driver state; it was stuck in a physical open-cover condition because the mechanism no longer pressed the sensor correctly.

Problem: HP Envy 7640 prints colors incorrectly even when ink levels look full

What users observed: Labels and graphics printed with incomplete or inaccurate colors even though the printer showed full ink levels. The output did not match what users expected from the file or design.

What was tried: Users ran cartridge cleaning and alignment routines. They also considered paper type, workflow, and nozzle condition because the issue appeared in labels and graphic output rather than only plain text.

How this played out: Full ink levels did not prove that the print path was healthy. Paper characteristics, nozzle condition, cartridge behavior, and printhead performance could still affect the result. The issue stayed closer to output-quality troubleshooting than a simple driver reinstall.
