Does my
printer need an appropriate on / off switch?
There are
more and more laser printers with the “soft” power button rather than normal on
/ off switch. We have seen this on inkjet printer, which includes only
low-power components, but it is a new development in laser printer, which have
greater power.
Any device
with a soft power button has a control circuit with power supply remains even
when the device is “off”, using several watts of power. On laser printer, this low
voltage circuit uses a reed switch (reed) to control the power source, keep it
off unless needed. It is as safe as a hand switch, but it means that the energy
using will not decrease to zero. If your laser printer has soft power button
and you do not intend to use it in a long time, unplug the main power source.
Epson Stylus Photo PX730WD

Stylus Photo PX730WD is a direct replacement for PX720WD, which won our Best
Buy award, so we are eager to see what it can do. It is a short and fast inkjet
MFP including printer, scanner and color copier. There is a tilt touch panel
with 6.3cm color screen, which presents several menus or content of the memory
card.
Specification
of PX730WD reflects the fact that it targets people who use photography and
other creative users. It can scan with 2400x4800dpi resolution, while the
printer is based on a long-standing Epson machine located in many hearts of our
favorite inkjets. Its 6-color ink setting contains cyan and magenta inks, for
printers with precise control with the pale colors.
Epson has
recently updated inkjet setup program for you to have more choices about the
components are installed, but everything seems more complicated than necessary
when choosing the interface between 3 interfaces in of MFP to use. We checked
with wired Ethernet connection, but it is only activated once the wireless
interface is turned off from the printer's control panel.
The prominent
“torn” in the first print documents reveal that the printer's printing head
should be aligned, but strangely, it is still manual process. Fortunately, it
is not thing the user needs to do regularly. Once be aligned, black text looks
nice in any quality setting except for Draft, which looks pale. Although color
prints are not vivid or strong on paper, stable color, and gradual color changing
without banding issue and very smooth. When using 75gsm paper, we found a
little leak from one side to the other side of the paper is in two-sided automatic
printing mode.
PX730WD has
its own position when printing pictures. It's pretty fast, even at the highest
possible setting, it offers a 6x4in photo in just 79
seconds, and the result is special. The combination of shades is rated
excellent and color accuracy offer the top ability to copy color and black and
white printing.
We are not
so impressed by the swivel of the scanner lid, which expanded a bit to
accommodate with thicker original ones, but the scanner itself is very suitable
for printer; combined together, they provide quite good copy. The scanner is
very fast, even when tested via an Ethernet connection, and get benefit from
the excellent TWAIN interface of Epson.
The focus
of scanner is extraordinarily sharp while colors are extremely accurate catch
up, but what makes it really stand out from competitors is the ability to
retain the full dynamic range of the original, including slightly different
shades of the darkest and brightest areas. Thanks to overall good performance,
excellent photo printing, elite scanning and reasonable operating costs,
PX730WD is MFP won the Best Buy.
Summary
Comment. There
are better MFP machines for general office works, but the Epson PX730WD is a
good choice for photo prints and best available scan.

LG Scanner Mouse LSM-100

LG Scanner
Mouse is wired laser mouse with built-in handheld scanner. It's better than
other portable scanner that we have seen, which slowly with difficulty and
often produce images with aliasing. Scanner Mouse allows you to scan all an
area of the text or graphics in almost any rate, shows a live preview on the
screen of the scanned content.
Using
technology developed by Dacuda - digital expert of Switzerland, Scanner Mouse
deployed a CMOS chip to record video of your scanning page. Video images are
processed and aligned with together in real time by installed software on your
computer to create static images. When you finish scanning, it will adjust the
alignment of the images were scanned at an angle.
The
software also has the optical character recognition (OCR) integrated, so when
finishing scanning, you can copy its text into any document. We are
particularly impressed by the software's ability to turn a scanned table into
separate text boxes to be pasted into an Excel spreadsheet. You can also copy
and paste parts of the scan as an image and share your scans on social
networks. OCR can process more than 100 languages, but can not interpret
handwritten text accurately.
The
scanner has a maximum resolution of 320dpi and an average and low resolution
mode are 200dpi and 100dpi. High resolution is best for the accuracy of OCR
when scanning the small font, but the scan at low resolution will reduce the
storage requirements for scanned images. This is very important, because the PC
interface of mouse only allows a limited storage for each scan. Volume of use
is indicated by a progress bar on the screen, next to your scanned image when
it appears on the screen, so you know when it is out of space.
Scan speed
at which applications run depends on the performance of the PC. Video preview
is shock on AMD E350 processor, but much smoother on the Intel Core i5-2500K.
One other limiting factor is the amount of memory allotted to scanner, which
determine the area size you can scan. The amount of memory is determined
automatically after scan software analysis system, but you can increase this
memory - but the program crashes when we increase it too much.
The
biggest problem of the Scanner Mouse is it is uncomfortable to use as the
mouse. It's very practical, and you may be familiar with it, but the flat sides
and glossy surfaces can not be compared with the structure of the labor
efficiency of other pointing devices. In addition to the normal mouse buttons, there
are 2 more buttons on the left. A button changes the scan mode while the other
button performs the functions of the 4th normal button like coming back 1 page
in the web browser. Mouse wheel controls zoom into scan mode.
This is
the best handheld scanner we've seen with incredibly accurate OCR, making it
excellent tool for anyone who wants to scan the pieces of texts, images or
tables. However, the rat of the product seems almost redundant. It saves the
USB ports and is convenient if you are “moving”, but LSM-100 will be equally
useful if it a scanner without installed mouse.
Summary
Comment. LG Scanner
Mouse can not be the best mouse we've ever used, but of course it is the best
handheld scanner we've ever tried.
