389-615 RC Sample Block Fail-B-#4-OutBSD-ON:BSD 6.12 Color Registration Control

During the B (rough adjustment pattern) patch detection, the #4 (Black) patch at the MOB Sen- sor Out side did not satisfy the defined number of valid sample blocks. (This is a hidden failure. The Color Regi Spec cannot be guaranteed and Data is only recorded in history.)

NOTE: •When this Fail occurs, select No. 004 in DC612 Test Pattern Print and check the print- out of the rough adjustment pattern to estimate the color position (In/Out). Before printing this test pattern, set the value of DC131 [870-207] to "7".

• When turning the power OFF, turn OFF the Power Switch first and then the Main Power Switch.

Initial Actions

When multiple failures with Chain No. 389 occur, take action according to the priority order in the following table. Solving a higher priority failure may sometimes also repair the other fail- ures. (Chain No. 389 Fail is detected during the execution of Regi Control. However, 389-617 is also detected during power ON.)

Procedure

Check the density of K color. Is the density of K color normal?

Adjust to correct the density of K color.

Check the connection between the MOB Sensor Out J151 and the MCU PWB J415 for con- nector disconnection, open circuit, short circuit, and poor contact. Is the connection normal?

1. 檢查 NVM [760-063]（Lead Regi Offset）的值是否為“0”。 如果該值不是“0”，則將其設置為“0”。

2. 檢查 NVM [760-082]（Side 1 Skew Offset）的值是否在 NVM [760-084] 和 NVM [760-085] 的值之間。 如果該值不在兩者之間，請將其設置為介於兩者之間。

3. 檢查 NVM [760-083]（Side 2 Skew Offset）的值是否在 NVM [760-084] 和 NVM [760-085] 的值之間。 如果該值不在兩者之間，請將其設置為介於兩者之間。
