HP Scanjet G3110 - Performance and Verdict



HP quotes a speed of 28s for a 15 x 10cm colour scan from the Scanjet G3110 and we saw 34s under test, which isn’t too far from the claim. Other times weren’t so good, though, with a 200ppi black text page taking 21s, a 300ppi greyscale page with OCR taking 1:01, and a 35mm slide at 2,400ppi clocking in at 1:51. Compare these with the cheaper http://www.trustedreviews.com/hp-scanjet-g2710_Peripheral_review HP Scanjet G2710, which took 19s for the 200ppi A4 and 44s for the 300ppi with OCR.

The 200ppi black and white text scan is suitable for archival and very readable, but there are a good few OCR errors in the 300ppi greyscale page scan. From text being reproduced at the wrong size, to characters being mis-recognised or substituted by punctuation marks, you would need to play about with the contrast settings in the driver to get satisfactory OCR results.

The 300ppi photo scan gave generally good colour, though it was a little over-vivid in foreground greens. The Q-60 target came through reasonably, with good gradations of colour across the palettes and well reproduced skin tones in the portrait image. The MTF target showed a blue tinge and resolution of the black and white gratings was similar to that from the cheaper scanner.

On the slide scan, colour, focus and relative illumination were all out and, although you wouldn’t expect to get the same quality as from more expensive devices, it looked little better than the result of the same test on the http://www.trustedreviews.com/hp-scanjet-g2710_Peripheral_review HP Scanjet G2710.

The quality of the scans was also marred by a number of specs on the underside of the scanner glass. Most scanners are built in semi clean-room surroundings, specifically so dust is excluded during assembly. While the specs may be isolated to this unit, if you get a scanner with this problem, there’s little you can do to fix it, other than get it replaced.

The HP Scanjet G3110 certainly looks the part, with its smooth curves and ice-white cover. It also looks good on the spec sheet, with a transparency adapter, single-button scan-to-PDF, scan-to-email and automatic dust removal. When you try it out, though, you realise plain paper scans are slow and scan quality is variable. If the driver glitch we hit is at all common, it needs to be resolved, soon.
