The SCX-4200 is a quick little device, as long as it’s warmed up. When it is, it can produce an A4 photocopy in around 10 seconds; when it isn’t, you can add 25 seconds onto that. It’s not unusual to have to wait for the lamp in a flatbed scanner to warm up and settle, but it’s quite unusual to have to wait for a laser engine.
Many companies are now using ‘instant on’ engines, but the Samsung device can take up to 35 seconds to warm up. In most offices, multifunction devices like this are used intermittently, so you may find yourself having to wait on most occasions.
Print quality is variable. On the good side, text print from a PC is very good; crisp and clean, but not over-emphasised. Greyscales from either colour graphics or photos are also acceptable, with smooth dither patterns giving well-separated tints. Our photo test picture came out clearly and with plenty of detail, given the printer’s 600dpi resolution, and text photocopies were close enough to their originals to get them confused.
Try as we might, though, we couldn't get the SCX-4200 to copy our text and graphics page adequately. The greyscales it produced happily while printing seemed to completely confuse its scan head when copying, so copies looked like they had come from a poor quality, mono-only fax machine.
We tried it in all three copy modes: text, text/photo and photo and only photo mode came close. Here, though, the light greys of the original were completely bleached out. Setting the device to print ‘dark’ improved things, but the copy was still a long way from the quality of the original.
There’s just a single consumable, the combined toner and drum cartridge and you should be able to find this for just under £50, if you shop around. With a claimed capacity of 3,000 pages, this gives a page cost of 2.04p, which compares favourably with most devices in the Samsung’s price range. You have to pay considerably more for a printer to get cheaper running costs.
There's a lot about Samsung’s SCX-4200 to like. It's small, inexpensive to run and, when it's warmed up, quick to use to print or copy. The drawbacks are, first, the length of time it takes for its scanner lamp and, more importantly, its laser engine to warm up and, secondly, the quality of copies from some graphic originals. Samsung needs to sort this out, as it detracts from an otherwise well-conceived multifunction device.
