II UNIT EXPLANATION
[27]
Drum potential sensor /K (DRPS K)
Detects the surface potential of the drum /K
[28]
Drum potential sensor /C (DRPS C)
Detects the surface potential of the drum /C
[29]
Drum potential sensor /M (DRPS M)
Detects the surface potential of the drum /M
[30]
Drum potential sensor /Y (DRPS Y)
Detects the surface potential of the drum /Y
DRDB/Y
Drum drive board /Y Drive board for the drum motor /Y (M14)
DRDB/M
Drum drive board /M Drive board for the drum motor /M (M15)
DRDB/C
Drum drive board /C Drive board for the drum motor /C (M16)
DRDB/K
Drum drive board /K Drive board for the drum motor /K (M17)
M14 Drum motor /Y Drives the drum /Y
M15 Drum motor /M Drives the drum /M
M16 Drum motor /C Drives the drum /C
M17 Drum motor /K Drives the drum /K
PS60 Encoder sensor /Y1 Detects the rotation of the encoder for the drum /Y
Manages the drive of the drum motor /Y (M14)
There are two sensors, PS 60 and PS61, at opposite of the
encoder to cancel the rotational fluctuations due to the eccen-
tricity of the encoder
PS61 Encoder sensor /Y2 Detects the rotation of the encoder for the drum /Y
Manages the drive of the drum motor /Y (M14)
There are two sensors, PS 60 and PS61, at opposite of the
encoder to cancel the rotational fluctuations due to the eccen-
tricity of the encoder
PS62 Encoder sensor /M1 Detects the rotation of the encoder for the drum /M
Manages the drive of the drum motor /M (M15)
There are two sensors, PS 62 and PS63, at opposite of the
encoder to cancel the rotational fluctuations due to the eccen-
tricity of the encoder
PS63 Encoder sensor /M2 Detects the rotation of the encoder for the drum /M
Manages the drive of the drum motor /M (M15)
There are two sensors, PS 62 and PS63, at opposite of the
encoder to cancel the rotational fluctuations due to the eccen-
tricity of the encoder
PS64 Encoder sensor /C1 Detects the rotation of the encoder for the drum /C
Manages the drive of the drum motor /C (M16)
There are two sensors, PS 64 and PS65, at opposite of the
encoder to cancel the rotational fluctuations due to the eccen-
tricity of the encoder
PS65 Encoder sensor /C2 Detects the rotation of the encoder for the drum /C
Manages the drive of the drum motor /C (M16)
There are two sensors, PS 64 and PS65, at opposite of the
encoder to cancel the rotational fluctuations due to the eccen-
tricity of the encoder
