Analog Output Test Device Code - Epson AcuLaser C8500 Service Manual

EPSON AcuLaser C8500
During high voltage output, never touch parts with high
W A R N I N G
voltage output or energized with high voltage.
When the laser is operating, always keep all covers in
place.
Never touch an operating drive section .
NOTE: To prevent electrification exhaustion, never execute [BCR] ON,
[ERASE LAMP ASSY] ON, and [ROS ASSY LD] ON when
[PROCESS DRIVE ASSY] is OFF.
NOTE: With [PROCESS DRIVE ASSY] ON, [FUSER-P/H MOTOR] ON,
[DEVE. CLUTHC ASSY] ON, and at each color development
position, never turn only [DB output (AC component)] ON or turn
both [DB output (AC component)] and [DB output (DC
component)] ON.
NOTE: Never turn ON for 10 seconds or more the [DISPENSE MOTOR
ASSY] at each color's development position. Otherwise a toner
jam or gear damage may occur.
NOTE: Never turn ON the 1ST BTR with the [PROCESS DRIVE ASSY]
OFF. Otherwise the IBT BELT ASSY may be damaged.
NOTE: Never turn ON the 2ND BTR with the [PROCESS DRIVE ASSY]
OFF and the [FUSER-P/H MOTOR] OFF. Otherwise the IBT
BELT ASSY may be damaged.
NOTE: To prevent dirt from getting into the printer and damage to the
gears caused by improper meshing, never execute [FUSER-P/H
MOTOR] ON or [DEVE. CLUTCH ASSY] ON when slightly
shifted from development position for each color.
