*2: Contact a Sharp customer representative for details on activating            
this function. 
• Eco Scan function saves energy by keeping the fusing system 
shut down during jobs that don’t require the use of the fusing 
system, such as Image Sending and Document Filing. 
• Second-generation Mycrostoner-HG has a lower melting point 
than conventional toner, allowing fusing to be carried out with 
less energy. It also offers a significantly lower consumption rate 
than conventional toner.
• For further energy savings, energy-efficient LED lamps are 
employed in the scan unit in place 
of conventional xenon lamps. A new 
ASIC (application-specific integrated 
circuit) also helps the MX-5140N/
4140N deliver excellent performance 
and energy efficiency.

Sharp OSA* 
(Open Systems Architecture)
Innovative Sharp OSA technology allows you to interact with critical 
business and network applications right from the LCD control panel, 
offering a new realm of control and convenience. And since Sharp 
OSA utilises industry-standard network protocols, the MX-5140N/
4140N can easily integrate with document management systems, 
enterprise resource planning software, workflow applications, and 
more. The latest version of Sharp OSA can reach beyond the 
firewall, enabling extensive system construction and services over 
the Internet. Sharp OSA brings benefits such as reducing the costs 
associated with system implementation and management, as well as 
enabling data sharing across company branch offices or 
subsidiaries—effectively enhancing total business efficiency.

ENVIRONMENT-FRIENDLY
• Sharp’s belt fusing system 
shortens the MX-5140N/
4140N’s warm-up time to 
30/28 seconds, contributing 
to reduced overall energy 
consumption. 
• Based on prior usage patterns, the MX-5140N/4140N 
automatically determines the optimal length of time to let elapse 
before going into auto power shut-off mode, helping reduce 
overall power consumption. Shortly before auto power shut-off 
mode begins, a message appears* on the LCD indicating that 
the MFP will soon shut down and giving users the option to 
continue operation.  
* Contact a Sharp customer representative to activate this pop-up 
message function.  
• Power ON/OFF Schedule function automatically turns the 
MX-5140N/4140N on or off according to time schedules set by 
the administrator.
