HOW TO RESET FUSER, TRAY 1 ROLLER, RETARD ROLLER, TRANSFER ROLLER COUNTERS ON SAMSUNG M3825, M4025

Does this have any negative effect??? For example, if you reset the toner counter to get the last couple of hundred pages printed before the cartridge is finally ACTUALLY EMPTY and you then insert a new cartridge - does this "corrupt" or "confuse" the counter??? Or does the counter reset again with the install of the new cartridge and operate correctly and accurately from then on??? I just want to be sure. Many thanks for your help. Grahame
