We expected the Samsung SCX-3405FW and the SCX-3405W to give very similar speed results, but were surprised. Samsung claims both machines are capable of 20ppm, but the 5-page document gave 11.5ppm and the longer, 20-page test gave 15.0ppm. This compares with 12.0ppm and 16.9ppm for the SCX-3405W, so not quite as fast.
This discrepancy is more obvious with the 5-page text and graphics print, which produced 8.8ppm on this machine, but 13.0ppm on the simpler one. The earlier tests were carried out from a PC running Windows XP SP3, before we upgraded to Windows 7 and we thought initially that the differences might be a function of the Samsung drivers for the two OS versions.
However, copying a single page from the flatbed took 13s here, while on the SCX-3405W it took 10s, so a similar speed difference, independent of any PC. A 5-page copy from the ADF took a more than respectable 27s and a 15 x 10cm print took 16s. Using Samsung’s Android App took a fairly laid-back 1:48 for a 20 x 15cm image.
Prints produced by the machine are generally good, with sharp, smooth text and fair greyscale graphics, though black fills are grey and grey fills look lighter than they should. A copy from the flatbed suffered some of the speckles you often see from CIS scans of printed originals.
The only running cost in the SCX-3405FW is the single-piece drum and toner cartridge, which is only available in one capacity, good for 1,500 ISO pages. With a best price of just under £40, this works out at 3.5p per page, including 0.7p for paper. This is a pretty good running cost for a sub-£150 all-in-one.
In most ways, the Samsung SCX-3405FW looks like a better buy than the SCX-3405W, as you get the ADF, fax functions and the two-line LCD display for very little extra on the base price. Running costs are the same, but under test this machine was slower and greyscale print wasn’t as clear. It may have been a problem with this sample, or course, but try and see a print sample before you buy.
