1.7 Safety Features
Tally stresses personal safety in both operating and maintenance related aspects. Hazard areas
have restricted access with applicable warning labels. Catastrophic failures are inhibited with
protective functions in major areas of overload potential. Some specifics:
Moving parts and areas of electrical shock hazard are covered to guard against inadvertent or
accidental operator contact.
The flexible fault handling system disables printing functions when normal operation cannot
continue, or when continued operation could harm the printer.
The power supply input is internally fused to protect against short-circuit and overload.
1.8 Maintainability
1.8.1 MTTR
Mean Time to Repair (MTTR) is predicted to be less than 20 minutes when repaired by a properly
trained technician utilizing replacement assemblies as recommended by TallyGenicom.

alignment adjustments and lubrication. It is recommended that occasionally the accumulated
