Confirming Line Power

Erratic printer problems can be caused by improper line power. As a rule, the voltage of the outlet should be checked at installation. However, if you are unable to isolate an inter- mittent problem, the power should be checked again. Consult your country’s national elec- tric code for the proper procedures to check for acceptable voltages, as shown in Table 1- 3, “Acceptable Voltages” .
