Brother MFC-7820N Laser Printer

What kind of printer is it? More info would help me answer the question.

The Brother HL-2040 machine does not have and cannot be fitted with a duplexer to print both sides of the page automatically. You can only duplex manually, that is - you turn the page over and put it back in the machine to print on the other side. Some settings will allow to print double sided manually, where the printer prints all the odd numbered pages then instructs the user to place ALL the printed stock back in the paper tray to then print all the even numbered pages.

With a home scanner you can only scan one side at a time. Some printer copiers are capable of double sided copies but the machines are big and bulky because they have to run the paper on one side then flip it over and scan the other side. These type machines are for office use. What kind of scanner are you trying to use? Is it the Lexmark as listed, if it is then it is not capable of scanning double sided documents. they must be scanned one page at a time.

The Konica Magicolor 1690MF Printer/Copier/Scanner is connected with an Ethernet Cable or USB Cable. It is not equipped to operate as a wirleless printer. It has a 10Base-T/100Base-TX Ethernet interface port and a USB Revision 2.0 High-Speed compliant port.
To do two-sided printing you must have the duplex (double-sided) option installed. This also requires either Tray 2 or the Attachment to be installed underneath your machine. Tray 2 is the optional lower feeder unit which increases capcity of your machine to 500 pages. The Attachment comes with the Duplex Unit.
Only Letter and A4 plain paper (16-20 lb bond) can be autoduplexed. With the duplex accessory installed you can do duplex or double-sided printing automatically.
From within Printer Preferences select Two-side Printing > Automatic. Shoud have choices of Off, Manual or Automatic. Within the Layout Tab for your work you may also be able to specify duplex (double-sided).
Should you have continued difficulty, please reply and advi e if the duplex option is installed and with which software and operating sysytem you are using.
Thank you for using FixYa!

If you have the software CD that came with the machine, the manual is on it.
The following paragraph is from Singer's Customer Service page:

• Is there a more extensive manual for the Futura™? Yes. With the basic Futura™ CD in the D drive, open up Windows Explore, by right clicking on the START button on the bottom tool bar. Left click on the drive and the contents of the CD will appear on the right side of the screen. Among the folders listed will be the Manual. Double left click on the icon. The manual is 92 pages and explains in detail all of the programs functions.
  

However if you have lost that CD, the Singer Asia Pacific site provides only accessory software CDs for purchase. You can try e-mailing Singer customer service in the form provided to see if they have the original CD in stock; otherwise you can purchase the tutorial CD.

actually, this machine is not design for bouble side printing, but you can manually do that if you want to, just need to open the front manual feed cover to do it.
