EPSON Perfection 1640SU Review

The EPSON Perfection 1640SU, though not the newest model on the market, has maintained a loyal user base thanks to its reliability and image quality. As an entry-level to mid-range flatbed scanner released in the early 2000s, it was designed to cater to home users and small offices needing to digitize documents, photos, and even transparencies with the optional transparency adapter. While its age now brings some challenges, many users continue to enjoy the service it provides. In this review, we'll examine common issues users face, provide troubleshooting solutions, and reflect on whether the 1640SU is still a viable option today.

Common Issues Users Experience with the EPSON Perfection 1640SU

Several years after its release, the EPSON Perfection 1640SU shows signs of aging that can create problems for its users. The main challenges are compatibility with modern operating systems, driver support, physical wear and tear, and scan quality concerns.

1. Compatibility and Driver Support:
   One of the most frequent issues is related to the lack of updated drivers for newer operating systems such as Windows 10, Windows 11, or recent macOS versions. Since Epson stopped updating drivers for this model several years ago, users often discover that the scanner isn't recognized after upgrading their computers. Software bundles such as Epson Scan or Smart Panel bundled with the scanner may not install or run without significant manual effort or workarounds.
2. Scanner Performance Decline:
   With prolonged use, the scanner can exhibit several hardware-related issues. The lamp inside the scanner can start to dim or flicker, which negatively affects scan quality, leading to faded or streaky images. The mechanical parts, such as the scanning head and gears, may also begin to make unusual noises or even stall due to dust, dried lubrication, or parts wearing out.
3. Image Quality Problems:
   Another common problem is deterioration in scan quality. Users may notice lines, bands, or spots on scanned images, or a reduction in resolution and color accuracy. This is often due to a combination of aging sensor components, dust on the scanning glass, or issues with the calibration strip inside the scanner.
4. Connectivity:
   The 1640SU uses a USB 1.1 connection. On newer computers, especially those using only USB 3.0 or USB-C ports, users might find compatibility issues or require additional adapters. Sometimes, the scanner won’t be detected despite being properly connected.
5. Transparency Adapter issues:
   For those who use the transparency adapter (for scanning negatives or slides), there can be difficulties in getting it to function, either because of software incompatibility or issues recognizing the adapter hardware.

Comprehensive Instructions to Fix Common Problems

Despite these challenges, many of the issues with the EPSON Perfection 1640SU can be overcome with a mix of software solutions, maintenance, and third-party support. Here’s how users can extend the life of their trusty old scanner.

1. Solving Driver and Software Compatibility:

• Windows Users:
  • Try installing the most recent official driver from Epson’s website, even if it is designed for an older version of Windows.
  • Use Windows Compatibility Mode: right-click the installation file, choose ‘Properties’, go to ‘Compatibility’, and set it to run in compatibility mode for Windows XP or Windows 7.
  • If the official drivers still don’t work, consider third-party scanning software such as VueScan or SilverFast, which offer built-in support for the Perfection 1640SU and are regularly updated to work on newer operating systems.
• Mac Users:
  • Check Epson’s official support page for legacy drivers. For post-Snow Leopard systems (macOS 10.7 and later), manufacturer support is limited.
  • VueScan is a reliable alternative, offering Universal Binary and regular compatibility updates for the latest macOS.
• For both Windows and Mac, ensure the scanner is connected directly to the computer (not via a USB hub) for maximum compatibility. If using USB-C, a USB-A to USB-C adapter may be necessary.

2. Maintenance to Improve/Restore Performance and Scan Quality:

• Cleaning the scanning glass:
  • Turn off and unplug the scanner.
  • Open the lid and, using a lint-free cloth and non-abrasive glass cleaner, gently wipe the scanning glass. Avoid getting any liquid inside the scanner.
  • For stubborn smudges, a mixture of water and isopropyl alcohol can help.
  • Inspect the white calibration strip (usually on the underside of the lid) and clean it gently if dirty.
• Dust and Lubrication:
  • Over time, dust can accumulate inside the scanner and hamper the movement of the scan head. If you’re comfortable with basic hardware tasks, you can open the scanner enclosure (after unplugging it) and use a can of compressed air to clean out dust.
  • Moving parts can sometimes benefit from a tiny amount of light, non-oily lubricant on the rails; be extremely cautious to use only the recommended type and amount to avoid damaging the optics.
• Addressing Dimming Light/Lamp Issues:
  • If scan quality is severely reduced due to a flickering lamp, replacement of the lamp is recommended; however, parts for this model are scarce.
  • If a replacement cannot be sourced, consider professional servicing, or repurpose the scanner for tasks where premium quality isn’t required.

3. Fixing Connectivity and Adapter Problems:

• USB Troubleshooting:
  • If the scanner is not detected, try different USB ports, avoid using hubs, and restart the computer with the scanner already plugged in and powered on.
  • On Windows, visit Device Manager to see if the device is listed or flagged for errors, and use the “Update Driver” option if relevant.
• Transparency Adapter Issues:
  • Ensure the transparency adapter is firmly attached and recognized by both hardware and software.
  • In VueScan, for example, select the transparency/film option.
  • Some Epson driver packages also require you to select the correct scan mode manually.
  • If the adapter is not recognized, try reconnecting or using another USB port.

Conclusion: Is the EPSON Perfection 1640SU Still Worth Using?

While the EPSON Perfection 1640SU has clearly been surpassed by modern scanners in terms of speed, resolution, and integration with current systems, it remains a capable workhorse for those willing to invest time in maintenance and troubleshooting. Its sturdy build and original imaging quality make it a sentimental favorite, and for simple document and photo scanning, it can still perform well, especially with the help of third-party software.

For users who only scan occasionally and don’t need advanced features, restoring or maintaining the 1640SU can be a cost-effective choice. However, for those seeking seamless compatibility, higher speeds, or integration with today’s cloud services and mobile devices, it may be time to consider an upgrade. Still, with the right tools and diligence, the 1640SU can continue to serve as a practical scanner for years to come.
