1 Error Code

1.1 E000-0102

 Description

Since the fixing belt did not separate from the fixing roller during warm-up rotation after
power-on, the error code ‘E000-0102’ was indicated.

- E000-0102 can be displayed when the fixing roller main thermistor detection temperature
does not reach 10 deg. C within 100 sec during warm-up.

Note:
When E000/E001/E002/E003/E004/E013/E717/E719 has been indicated, take the appropriate
remedial action, and turn the main power switch ON; then execute the following service mode:
COPIER > Function > CLEAR > ERR. After this, turn the main power switch OFF/ON to clear
the error code. At this time, be sure to switch on the pick-up/delivery option before the main
power of this machine. Otherwise, this machine will fail to recognize the option.

 Cause

Since the roller fixing spring [B], which retains the end of the fixing belt [A], contacted to the
screw [C], and thereby was deformed, the fixing belt failed to separate from the fixing roller [D].
This caused the fixing belt to deprive temperature of the fixing roller, as a result the fixing roller
failed to reach the appropriate temperature within the specified period of time, resulting in the
error code.

 Field Remedy

1. Check to see if the roller fixed spring [B] (rear) has been deformed; if so, replace it.

2. If the spring has not been deformed, move the fixing belt up and down while pushing it
slightly toward the rear, and then check to see if the roller fixed spring contacts the
screw [C].

3. If the spring contacts the screw, change its type from double sems screw M4x8 to
M4x6.

Reference:
The following are the starting serial numbers having the double sems screw M4x6.

1.2 E007-0001

 Description

When the main power switch of this machine was turned on, the error code ‘E007-0001’ was
indicated. This was because the tracking detection arm adjusting plate of the first fixing
assembly was fixed at an improper position, and thus the tracking detection arm that detects
the position of the pressure belt failed to track the edge of the belt.

- E007-0001 can be displayed when the pressure belt of the first fixing assembly has been
displaced completely.

 Cause

Since the tracking detection adjusting plate [B] that contacts the pressure belt [A] was disposed
at a slightly higher position, the tracking detection arm [C] contacted the separation roller [D],
and thus failed to track the belt edge. This caused the sensor flag to block off the light from the
primary fixing pressure belt position sensors [E] (PS301 and PS302) simultaneously, causing
the error code.

To deal with this, the accuracy of position adjustment of the tracking detection arm adjustment
plate was improved from the machines having the following serial numbers.

 Field Remedy

When the same symptom occurs with a machine having a serial number earlier than the above,
adjust the position of the tracking detection arm adjusting plate in reference to Appendix 1

‘Tracking Detection Arm Adjusting Plate Adjustment Procedure.’

Note:
The screw securing the tracking detection arm adjusting plate is fixed with a (red) bonding
material and generally is not removed. When the adjustment is finished, be sure to fix it with a
bonding material.

1.3 E012-1080

 Cause

There are some reported instances from the field where E012-0180 occurred because the
primary transfer roller was omitted to pressurize at the time of installation. This caused
insufficient tension to be applied to the ITB belt and a rotational failure of the belt.

1.4 E014-0100

 Description

There are some cases where E014-0100 occurred because the transmission shaft, which is
used in the transmission drive unit in the first fixing assembly lower, was chipped.

- E014-0100 indicates an error of the fixing drive motor (M300) in the first fixing assembly.

 Field Remedy

When a similar symptom occurs, inspect the shaft and replace it with a new one if chipping is
confirmed.

Note: Do NOT loosen 2 screws (which fix the transmission drive unit, red circle in the picture)
because the shaft and the gears can be replaced without removing the screws. Be aware of red
marking on them.

 Description

There are some cases where the feed screw of photosensitive drum cleaner locks and causes
E016-0x00.

 Cause

If outputting high volume of low duty image, waste toner may clog at the waste toner joint
assembly.

 Measure for factory

An agitating spring is added to break down the waste toner accumulated at the waste toner joint
assembly. Bringing waste toner feed screw into contact with the agitating spring and moving it
up and down can prevent clog prevented at the joint assembly.

1.6 E018
< Case 1 > E018-0x11

 Description

There are cases where E018-0213 was caused by malfunction of the drum patch shutter or a
soiled patch sensor, or malfunction of the patch detect cleaning motor.

 Cause

When continuously printing high-density image (solid image), scattering toner may accumulate
around the drum patch sensor shutter, and may burrow into minute clearance between the
shutter lever slider and the guide. Accordingly, this will make the movement of the shutter lever
dull and fail to detect the patch, resulting in an error of the drum patch sensor shutter drive
motor.

 Field Remedy

1. Clean the shutter lever slider and the guide, with lint-free paper moistened with alcohol.

2. Remove the drum patch sensor cleaning motor from the developing rail assembly. Clean

3. Replace the motor with a new one. After installing, turn the main power switch OFF/ON.

4. If the symptom still occurs, replace the developing rail assembly with a new one.

< Case 2 > E018-0x13 keeps displaying after power-OFF/ON to
clear 070A Jam Code or E733-0001

 Description

There are some cases where E018 displayed after power-OFF/ON to clear 070A Jam code or
E733-0001.

- 070A can be displayed when the registration paper feeder assembly does not transfer paper
in time for the start of paper-feeding operation. (Related sensor: pre-feed sensor 3 PS141)

- E733-0001 can be displayed when communication with the printer (DC controller PCB 1-1)
is not established at startup.

- E018 can be displayed when a shutter operation error occurs.

Reference:
When turning off the main power switch, be sure to turn off all the optional equipment as well as
the main engine. When turning on, turn on the optional equipment first, and then the main
engine.

Rotate the gear by hand

 Field Remedy

In order to deal with this malfunction, the DC controller software has been updated to Ver.12.04.
When the same symptom occurs, check the software version, if it is earlier than Ver.12.04,
upgrade to Ver.12.04 or higher.

As a difference case, the warm gear at the rear side
may get onto the engaging gear. In such a case,
rotate the warm gear in counter clockwise to ease
this state.

< Case 3 > E018-0102

 Description

There are some reported instances from the field where the machine was restored from
E018-0102 after cleaning the edge registration detect assembly. When the same symptom
occurs, go through the following steps in sequence.

- E018-0102 is displayed when the edge registration patch sensor causes shutter-related
error.

 Field Remedy

1. If the side scraper (FL2-2025) in the edge registration detect assembly has been soiled like

[1]; clean it, then turn the main power switch OFF/ON.

If the symptom still occurs, clean or replace the 30T/63T gear [2] (FU6-0381), the 60T gear
[3] (FU6-0382) and the 60T gears [4] (FU6-0383, 3 pc) that drive the shutter, then turn the
main power switch OFF/ON.

4. If the symptom still occurs, replace the edge registration detect sensor with a new one.

1.7 E061-0181

 Description

There are some reported instances from the field that E061-0181 was solved by replacing the
P-kit drawer assembly (FM2-2079) with a new one, not by replacing the primary corona
assembly. In this field case, service mode COPIER > Display > V00 showed 905V and VFF
showed 802V.

Reference:
The difference in voltage between V00 and VFF normally falls in the range between 400V and
500V.

- E061-0181 is a low laser power error, and can be displayed when the difference in voltage
between VD and VL at the maximum potential control laser power output is 200V or lower.
The meaning of the second digit of detail code is as follows: 1= yellow, 2=magenta, 3= cyan,
and 4= black.

 Cause

Since the spring terminal of the H.V. cable to which grid bias is applied was deformed,
unexpected amount of electrical charge was carried, causing the error code.

 Field Remedy

Perform the following Steps 1 though 5, which the service manual describes, if the symptom still
recurs, perform Step 6.

1. Clean the dust-proof glass.

2. Re-fit the drum unit.
Note:
Be sure to connect the connectors of the potential sensor and the pre-exposure lamp.

5. In service mode > COPIER > Display > DPOT, check the values of V00-Y (M/C/K)
through VFF-Y (M/C/K). If those values are nearly same, the laser does not go on. In
this case, check the connection of the video cable.

6. Re-fit the primary corona assembly.

7. Replace the following parts.

 Potential sensor
 Laser scanner unit
 Primary corona assembly

8. Check the spring terminal of the H.V. cable of a trouble P-kit for deformation or
disconnection; if there is a problem, replace the drawer connector with a new one.

Since the magenta drum reached the end of life, the primary corona high voltage leakage
occurred at an end portion of the drum, consequently causing either the error code ‘E065-0201’
or blurred band-like image at random in the main scanning direction.

- E065-0x01 can be displayed when the primary corona high voltage leakage has been
detected for 300msec (100msc x 3 times) continuously 200msec after output of the primary
corona high voltage starts. (Y = 1, M = 2, C = 3, and Bk = 4)

 Field Remedy

1. In service mode > COPIER > Counter > DRBL-1 > PT-DR-M, check the counter reading; if
it is in the order of 580000 or higher, replace the magenta drum with a new one.

Bk = PT-DRM, Y = PT-DR-Y, C = PT-DR-C

If the symptom still occurs, go through the following steps.

9. Turn the main power switch OFF/ON.

10. Refit all the connectors of the primary corona assembly, and UN137 through UN140
connectors of the HV1 PCB. (Make sure of no uplift connectors.).

1.10 E077-0001

 Description

There are some reported instances from the field where, during initial rotation after clearing a
jam at the main station and closing the front cover, the error code ‘E077-0001’ was displayed.

- E077-0001 displays when engagement/disengagement of the secondary transfer external
roller cannot be completed within 5 sec.

 Cause

Since the lever (B-E1) on the Registration Paper feeder assembly (at the main station) is not
securely locked, engagement/disengagement of the secondary transfer external roller cannot
be completed normally.

 Field Remedy

1. If the same error code appears when the front cover is closed after work, check to see if the
lever (B-E1) is shifted to the locking position; if not, shift it again. If the lever is in the locking
position, go to Step2.

Note:
If the lever is locked at the wrong position, the lower portion of the cover may not be fitted
completely although the upper portion does so. After the front cover is closed, be sure to
make sure that both upper and lower portions fit completely to the main body.

13. Refit the connector of the secondary transfer pressure release motor (M184).

14. If the symptom still occurs, replace the secondary transfer pressure release motor with
a new one.

*1 Soil on the ATR sensor

 Field Remedy

1. Clean the ATR sensor with alcohol.

Note: Wipe the sensor in one direction more than 3 times. Do NOT wipe it back-and-forth.

7. Replace the ATR sensor with a new one.

In addition, for the purpose of preventing any future occurrence, follow the steps below.
a. Service mode(Level 2) > COPIER > Adjust > DENS > HLMT-PTY/M/C/K,

Settings: If the current value is 4, change it to 9.

Note:
Density might decrease as a negative effect. Therefore, execute the above setting value
change only if soil on the sensor occurred at less than 250K intervals of periodic cleaning
maintenance for ATR sensor.

Or

b. Shorten the interval of cleaning maintenance.

If the current value is 9, change it to 10.

*2 Image density is too low

As possible causes of low image density, soiled primary charging assembly, faulty laser, soiled
dust-proof glass, faulty drum, faulty developing, and etc. are conceivable. However, faulty
developing is the most likely. For this reason, check the area around the developing assembly
first.

 Field Remedy

1. Check the area around the developing assembly.

 Are there occurrences of Tiger stripe?
 Are there occurrences of developer overflow?

If these symptoms have occurred, replace the developer after taking actions such as
cleaning.

1. If there is no abnormality found at the step 1, output PG5 of the corresponding color
with density settings ‘80’ and ‘255’. Check the density and unevenness.
