14.3.21 E061
Code Detail
E061 At time of potential control, a specific level of potential is absent. Or, the limiter goes on.
0001
When forming an image, the potential is 10 V or less during initial rotation.
0002 At time of potential control, the potential is 10 V or less during initial
rotation.
0003
While the grid bias is being adjusted, a level of potential higher than the grid
bias is sampled.
0005 The difference in potential between dark and light areas is less than 100 V.
0007 During adjustment of EPC offset, the potential that is read is outside
the +/ 30 V range.
0008 During dark area potential adjustment, the sampling value is too low.
0010 The sampling of the light area potential is faulty.
14.3.22 E070
Code Detail
E070 There is an error in the detection of the ITB home position.
xx=01: HP1, xx=02: HP2; only at ITB 1/1 speed; XX=00: no distinction
00XX The home position of the intermediate transfer belt is not detected
within a specific period of time (4 sec).
The ITB HP sensor is faulty.
01XX The period of time between when the home position of the
intermediate transfer belt is detected and the next home position is
detected is longer than specified (standard period +5%).
The presence of a tear may have caused the sensor to wrongly
identify it as indicating the home position.
02XX The period of time between when the home position of the
intermediate transfer belt is detected and when the next home
position is detected is shorter than specified (standard time 5%).
The intermediate transfer belt slips on the drive roller, causing a
delay in the timing at which the home position is detected.
03XX The detection of the home position of the intermediate transfer belt
has failed once.
ITB HP1 and ITB HP2 must occur alternately; however, the same
state has been detected continuously.
