A:
Both the 49A and the 49X use identical toner. They only differ in total toner capacity. Darker output can result from changes in printer settings, either on the printer or in the software print driver preferences. Another possible explanation is that lighter print is a sign of a cartridge low on toner. The last hundred sheets from an emptied cartridge will be much lighter than the first hundred pages a full cartridge. Given two new, full cartridges, a 49A should produce output just as dark as a 49X.
