Toner density sensor trouble

Causes

Toner density sensor output abnormality (Sample level 25 or less, or 201 or above) Connection trouble of the connector and the harness. Developing unit trouble. PCU PWB trouble.

Remedy

Replace the toner density sensor. Check connection of the connector and the harness. Replace the developing unit. Replace the PCU PWB.

Description

Toner density sensor trouble (Y)

Causes

Toner density sensor output abnormality. Sensor connector and harness connection trouble. Developing unit trouble. PCU PWB trouble.

Remedy

Replace the toner density sensor. Check connection of the sensor connector and the harness. Replace the developing unit. Replace the PCU PWB.

Description

Toner density sensor trouble (K)

Causes

Toner density sensor output abnormality. Sensor connector and harness connection trouble. Developing unit trouble. PCU PWB trouble.

Remedy

Replace the toner density sensor. Check connection of the sensor connector and the harness. Replace the developing unit. Replace the PCU PWB.

Code C2556
Abnormally high toner density detected yellow TCR sensor
• TC ratio in the developing machine, which is determined by toner replenishing amount control mechanism, is 11 % or more for a given number of times consecutively. • When the connector of the TCR sensor is disconnected.
Solution:
1 Reinstall imaging unit. 2 Reinstall toner cartridge. 3 M3, M4 operation check (At this time, IU must be non-installation.). 4 Change imaging unit. 5 Change PRCB

Toner motor trouble. Toner density sensor trouble. Connector/harness trouble. PCU PWB trouble. Toner cartridge trouble. Developing unit trouble. Toner transport pipe section trouble

toner density trouble,
check developer mag sensor located at bottom of DV unit
check toner motor ,
check DV-unit gear assembly

• F2 with sub code 00 - Toner Sensor problem, ID pattern reading error;
• F2 with sub code 02 - Toner Motor problem, check toner dispenser motor;
• F2 with sub code 31 - Image Density error, Check the light level or the drum surface reflectivity;
• F2 with sub code 32 - Drum Mark sensor, missing/dislocated mark or sensor faulty. Sensor cannot scan mark properly;
• F2 with sub code 33 - grid voltage wrong, either too high or too low;
• F2 with sub code 35 - grid voltage correction will not work during simulation;
• F2 with sub code 37 - drum mark sensor adjustment required.

Content Process control trouble (OPC drum
surface reflection rate abnormality)
Detail Usually the sensor gain is adjusted so
that the output is a certain value, by
reading the drum base surface with the
image density sensor before starting
process control.
However, a certain output is not obtained
by adjusting the sensor gain.
Cause Image density sensor defective
Check Check process control sensor output with
SIM44-2. (Do not adjust)
and
remedy If the result is far different from the
specified value, it suggests the sensor is
defective. Check the sensor and harness.

If the deviation is relatively small, check
the sensor and drum surface for
contamination.
