Samsung SCX-5635FN Multi-Function Laser


Product: Samsung SCX-5635FN

It has been a long time since we had a Multi-Function unit on the bench.  The last product we took a look was the SCX-4521F, also from Samsung.  This unit was a bit smaller than the SCX-5635FN and even though it has pretty much the same features as the larger unit we're looking at today.  This unit brags up to 35 pages per minute and has a high enough duty cycle to replace a leased copier from a small office.  It is certainly no replacement for a busy office machine, but I wouldn't be surprised if this could easily replace a large unit in many small offices without any loss in production.


The SCX-5635FN functions as a copier, printer and a fax machine that can duplex any of the above and output high-quality copies at 1200dpi.  It can scan to a device on your network or to a USB drive plugged into the included USB port.  It has the ability to be configured by a very intuitive menu system using the on-board display, or even though a web interface.  Before I get too involved, let's take a look at the machine and see how it shapes up.


First Look:

The feature list on the SCX-5635FN is pretty large and this matches up nicely with its size.  It's quite a bit unit that will require more room than a standard fax machine or your typical small-medium laser printer.  It has a similar footprint to a CLP-600N laser printer - which is a beast.

The Multi-function comes with everything you need to get started and keep going for a while.  Samsung includes a software CD for the printer/scanner support, a starter (4,000 page) toner cartridge with a 10,000 page cartridge available.  Also in the bundle is a quick install guide, power cable and a phone cable.

One thing I really like about higher-end multifunction printers is the ability to use the Automatic Document Feeder on top or use the regular flatbed scanner.  Unfortunately the SCX-5635FN doesn't have an expandable hinge so think objects like books will be a bit more difficult to scan.  With that said, let's head on to the next page and take a look at the features and specifications before we continue.

On the next page we'll take a closer look before we jump into testing.


Closer Look:

The SCX-5635FN is a pretty traditional looking multifunction printer and like most other printers in this class, it has a secondary tray for special paper or envelopes that can flip down on the front.  This unit also has the ability to add a second bottom tray as we'll see when we look at the back in a few minutes.  When using the standard tray and specialty tray included, you still have the ability to choose paper sizes from 3"x5" to 8.5"x14" and this should satisfy most users.

The Automatic Document Feeder on the top can handle up to 50 sheets and works very well.  I never had any jamming issues when copying and faxing multi-page documents.

It is nice that the "starter" toner cartridge is a large 4,000 page unit and that the SCX-5635FN supports a toner cartridge that has a 10,000 page rated yield.  The imaging drum and all essential components are located on the actual toner cartridge and while this may make the toner slightly more expensive, it also ensures that you won't have to replace other components on a regular basis.  This unit is rated to have a 80,000 maximum monthly duty cycle, and while I doubt that it could do that for an extended period of time, it certainly should be able to stand up in a typical small office environment.

As far as connectivity goes, there is a front USB port that allows you to scan documents directly to a USB flash drive and on the rear we have more traditional connections.  The "N" in the SCX-5635FN indicates that it is a network printer, and we find the typical 10/100 Ethernet connection on the rear as well as standard USB2.0 input as well as a second USB2.0 output, additional tray feed, and the telephone input - output connections for the fax feature.  In terms of upgrades, you can add more memory as well as a wireless LAN option if required.



On the last page we'll run through some tests and see if the SCX-5635FN stands up to its rated specifications and talk about function and print quality.

General Usage and Testing:

As previously mentioned, the SCX-5635FN is designed to work in office environments that have a medium workload.  Many of these offices lease a copier that is much more expensive and has a much higher rated duty cycle than they need.  The SCX-5635FN is really built to shine in these situations.  While it may only be a monochrome device, the price:performance ratio is very good.  It has a lot of features including a G3 rated fax that is capable of 3 seconds per page transmission and receive speed.  In order to reach these speeds, you'll need good phone lines capable of 33.6kbps and an equally fast machine at the other end.

Faxing can be done through the ADF, flatbed machine or directly from your PC using the included software.  As this is a network machine, anyone on the network has access to print directly to fax.  Printing faxes can be delayed, single-sided or duplex as you choose.  You can use the intuitive on-screen controls on the device to set this up or make changes through the software or web interface.

Printing and copying have the same duplex options and you can choose to save paper or print single-sided on the fly.  Although many people don't use a scanner anymore, the SCX-5635FN gives you the option to scan and save documents to a network device, computer or a drive plugged into the USB port.  While this may not be its greatest selling feature, it is nice that they still offer this flexibility.

Samsung claims up to a 35ppm print speed on this device and we thought we'd test it out to see if they are even close.  We ran through several scenarios and have the results below.  When recording the times, we included the delay it takes to process the document and get the first page printed.  Samsung claims this is under 8.5 seconds and we noticed that this was accurate.  The times listed in the chart below include the initial delay.  If you subtract that 8.5 seconds, you'll see that when printing a large single-sided document, it does indeed reach the rated 35ppm speed.

Output Speed

Single-sided printing is blazing fast and like all printers, duplex takes a performance hit.  When printing a word document we see the speed drop from 35ppm to 19ppm.  This is still a respectable speed, but it takes almost twice as long to save half the paper.  Copying is a similar story and while the speed is slower, the above reported times include scanning the document as well as printing it.  You can see by comparing the 2 Page - 7 Copy output and the 14 Page - 1 Copy output that scanning documents is the bottleneck.  With that in mind, it is still a pretty speedy machine - must faster that the SCX-4521F.


Final Thoughts:

The SCX-5635FN is a nice machine that is a great upgrade from the aging SCX-4521F and this one supports Duplex printing as well as network functions giving it a better fit in a small office.  The copy features are very good and include enlargements, automatic document feeding, duplex copies and more.  Faxing and printing follow the same suit and that makes this machine very appealing.  You can find it online for ~$500 and while this may be more expensive than other devices consider the duty-cycle and and fit in your office.  It can pump out up to 80,000 pages per month and has large toner cartridges that yield up to 10,000 pages.  This makes it a great fit for those that may be spending $100 / month or more on a leased machine that does the same thing.  In less than six months, this would be paid for.

Setup and menu navigation is intuitive, print quality is stellar and the feature list is long enough to be very appealing.  It is simple to use, doesn't make a lot of noise and there is really nothing bad to be said about this product.  We connected it to our network and pounded it from multiple machine and weren't able to make it choke.  When using it hard from several machines, the paper tray gets empty fairly quickly and it would be nice to see it include a 500-sheet tray instead of the smaller 250-sheet tray.  Other than that, it's a top-notch product.


  • Great device for small offices
  • Fast, high quality print speed
  • Duplex available on fax, copy and print
  • Expandable tray option to add another paper type
  • Network ready and can be configured through software or web interface
  • Easy to use menu system



  • Not a small unit - will take up a good chunk of desk space
  • Main paper tray is only 250 pages - on a 80,000 page / month machine. 



I'd like to thank Samsung for sending this device our way.  It does everything I expected and does it well.  I just wish I didn't have to send it back.  It is a great upgrade from my existing SCX-4521F.
