Transparent materials adapter (TMA)

You can use the transparent materials adapter (TMA) to scan 35 mm slides or negatives. With the HP Scanjet G4050 TMA, you can also scan medium- and large-format film. For more information about the TMA, see Scan film.

Scanning overview

Start scanning in one of these ways:

Image quality (6-color scanning) vs. speed

When scanning images using the HP Scanjet G4000 series scanners, you can configure the scan settings for either fast scanning or higher-quality output. If you choose to take advantage of this product’s high quality output by using the optimum color accuracy options, the scanning process will be slower.

The HP Scanjet G4000 series scanners include the 6-color scanning feature. This technology makes it possible for a scanning device to detect a wider range of color. The result is more realistic photo reproductions with greater color accuracy. The term 6-color refers to amount of information collected for each pixel during the scanning process, not the number of colors in the output.

Tip Try the higher-quality scan settings first on a small number of images, especially when using the HP Scanjet G4050 TMA. This will give you an idea of the scan speed so that you know what to expect when you scan a larger batch of images.

If you are unsure whether the program is compliant or what the option is, see the documentation for that program.

Tips for scanning transparent items

  • To scan items larger than those that the transparent materials adapter (TMA) or template accepts, place the transparency on the scanner glass, place a white sheet of paper on top of the transparency, and then scan as described in Scan pictures.
  • When scanning a 35 mm slide or negative, the scanner software automatically enlarges the image to approximately 10 cm x 15 cm (4 x 6 inches). Medium and large format negatives are also scaled to a larger final size. If you want the final image to be larger or smaller, use the Resize tool in the scanner software to set the scaling to the final size that you select. The scanner will scan the item to the size that you select and adjust the scan resolution as appropriate.
  • You can configure the scan settings for either fast scanning or higher-quality output. If you choose to take advantage of this product’s high-quality output using the optimum color accuracy options, the scanning process will be considerably slower. For more information, see Image quality (6-color scanning) vs. speed.
  • When cropping images, completely remove the borders to reduce excess light interference.

Care and maintenance

This section presents information about how to care for and maintain the scanner.

Occasional cleaning of your scanner helps ensure higher-quality scans. The amount of care necessary depends upon several factors, including the amount of use and the environment. You should perform routine cleaning as necessary.

For all care and maintenance procedures required for the scanner, please see the Care and maintenance section for your scanner in the onscreen Help. In the HP Solution Center, click Help, and then select the Help section for your scanner model.

Routine cleaning and maintenance should include cleaning the scanner glass and the transparent materials adapter (TMA).

Caution Avoid placing items that have sharp edges in the scanner. Doing so can damage the scanner. Before placing an item on the scanner glass, make sure that the item does not contain wet glue, correction fluid, or other substances that can be transferred to the glass.
HP Scanjet G4050 User Manual 95

Clean the scanner glass

  1. Disconnect the USB cable and power cable from the scanner.
  1. Clean the glass by using a soft, lint-free cloth that has been sprayed with a mild glass cleaner, and dry the glass with a dry, soft, lint-free cloth.

Caution Use only glass cleaner. Avoid abrasives, acetone, benzene, and carbon tetrachloride, all of which can damage the scanner glass. Avoid isopropyl alcohol because it can leave streaks on the glass.
HP Scanjet G4050 User Manual 95

Do not spray the glass cleaner directly on the glass. If too much glass cleaner is applied, the cleaner could run to the edges and damage the scanner.

  1. When you have finished, reconnect the USB cable and power cable to the scanner.

Note For instructions about how to clean the underside of the scanner glass, visit www.hp.com/support.

Scanner initialization or hardware problems

This section contains solutions for initialization and hardware problems.

Reset the scanner

If you receive an error message similar to “Scanner initialization failed” or “Scanner not found” when trying to use the scanner, use the following procedure:

  1. Close the HP Photosmart software, if it is open.
  1. Disconnect the cable that connects the scanner to the computer.
  1. Turn the computer off, wait 60 seconds, and then turn the computer on again.
  1. Reconnect the cable that connects the computer and the scanner.

  1. Disconnect the USB cable and power cable from the scanner.
  1. Reconnect the USB cable and power cable to the scanner.

The carriage on the scanner will move forward and backward approximately 25 mm (1 inch), and the lamp will turn on.

If the carriage does not move and the scanner lamp does not turn on, a problem might exist with the scanner hardware. See Scanner has stopped working properly.
