Re: Please help canon c7000vp
are u a tech
if not>>>> call for service 
x= 1:Y 2:M 3:C 4:Bk
0386=CYAN
0x86 Fault at sampling 2 in patch image
DISPLAY>DENS>DENS-S-Y/M/C/K(Measured value of patch image)
DISPLAY>DENS>P-B-PY/ M/C/K(measured value of drum base) </= 30
Highly possible= 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.
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 actions such as cleaning.
2) 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.
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Low possible= Soil on the ATR sensor, Faulty pressure for developing assembly, Broken wire of ATR sensor, Damaged ATR sensor, Malfunction of ATR patch
detection shutter.
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.
2) Replace the ATR sensor with a new one. In addition, for the purpose of preventing any future occurrence, follow the steps 2-1. or 2-2. below.
2-1) Service mode(Level 2) > COPIER > Adjust > DENS > HLMT-PTY/M/C/K,
- If the current value is 4, change it to 9.
- If the current value is 9, change it to 10.
[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.
2-2) Shorten the interval of cleaning maintenance.
================================================== ================================================== =========================
Check the developing motor
Clean the patch sensor
Check if the harness for patch sensor is shorted out
1. After cleaning the patch sensor, execute FUNCTION>MISCP>PTLPADJ-Y/M/C/K -> check the DISPLAY>DENS>P-DA-Y/M/C/K value (1)
2. After removing the patch sensor shutter, execute FUNCTION>MISCP>PTLPADJ-Y/M/C/K -> check the DISPLAY>DENS>P-DA-Y/M/C/K(level2) value (2)
3. If (1) = (2): Go to Remedy 4
If (1) > 240, (2) < 170: Replace the shutter and the shutter motor
4. If (1) = (2) and also the value is 255: Replace the patch sensor
Normally, the Film Shutter is closed to eliminate soil on the window of the Drum Patch Sensor.
At the time of patch detection, turn ON the Drum Patch Sensor Shutter Solenoid, pull the wire and open the Film Shutter. Also, open and close the Film Shutter to
execute the background detection between papers before ATR patch detection is executed.
Since the position of patch images is different between Y/M color and C/Bk color, the position of the Drum Patch Sensors is different.
In addition, patch images of Y/C color and M/Bk color are formed alternately between sheets.
Since the position and timing to form patch images of 4 colors are different, the patch images of 4 colors are not overlapped on the ITB.**Knowledge is time consuming, exhausting and costly for a trained Tech.**

Re: Please help canon c7000vp
I run into this one a lot when the shutter motor at the back of the process assembly (for whatever colour) is dirty or binding a bit. Sometimes you just need to make sure that the shutter on the developer is not sticking when you slide it in, and that the motor at the back of the entire process assembly is clean....
Get your vacuume out..couple of screws to take out and a few connectors.
DPOT values can help if you're not sure about drum or corona assembly.Comment
