The L6370 and ET-3750 share printing, scanning and copying, automatic duplex printing, Wi-Fi and Wi-Fi Direct. Their confirmed differences are set out below. These shared entries establish a common baseline and do not, by themselves, favour either model. The specific differences below can guide your choice by need.
L6370 supports automatic duplex scanning; ET-3750 explicitly does not; Black ISO print speed is 18 versus 15 ipm for L6370 and ET-3750, respectively; Colour ISO print speed is 9 versus 8 ipm for L6370 and ET-3750, respectively; Included colour ink yield is listed at 11200 versus 5500 pages for ET-3750 and L6370; ET-3750 lists 12 versus 15 W of operating power for L6370.
The L6370 may suit a need for automatic two-sided scanning, while the ET-3750 may suit someone prioritising higher stated included-colour yield. Consider the actual functions, throughput, and paper format required. An entry supplied for just one model is insufficient to conclude that the other lacks the feature.
