User Permissions 4 This symbol indicates user permissions for general users who have been trained in the operation of the machine by Epson or an H user, to perform cleaning and simple maintenance procedures while protective devices are engaged and the machine is set to normal operation on the button panel. “L” is assigned to the operator of the machine. This symbol indicates user permissions for users who have been officially trained in the operation of this machine by Epson or an H user, to perform some functions and maintenance procedures that are allowed in addition to all of the functions for L.
“H” is assigned to the machine administrator, who manages maintenance keys and is in control of jobs in general. This user must inform User L of the information in this manual, and have access to the manual at all times. Checks and maintenance can be performed routinely or in unusual situations only if formal training has been received from Epson or an H user. It is strongly recommended to make all L users aware of their responsibilities when operating this machine. To that end, it is also important to collect from them all information regarding recommen- dations, complaints, suggestions, and anomalies that might occur.
