Received this error code today. Doe anyone have any idea what this refers to and if there is anything we can do before the technician can make it out?
Thanks in advance!

E020-0386=========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
Check uniformity of the image
-> Check the developing motor
->Check the DISPLAY>DPOT>P-LPW-Y/M/C/K (patch laser power value)
1-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 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.
2-Soil on the ATR sensor
3-Faulty pressure for developing assembly
4-Broken wire of ATR sensor
5-Damaged ATR sensor
6-Malfunction of ATR patch detection shutter
how old is CYAN DRUM & DEVELOPER ?? Last time changed
The more deteriorated the developer grows due to the long-term operation, lower is the toner density that attaches to the photosensitive drum.
This machine quantifies the developer life with the internal counter and adjusts the toner density by changing the upper limit of toner T/D ratio depending on the counter reading.
**Knowledge is time consuming, exhausting and costly for a trained Tech.**
