only black engaged condition, the sequential operation for engagement/disengagement is repeated again.
(2) Abnormality detection
If a conflict of operation still occurs, the error message "E078 (abnormal transfer roller charging estrangement mechanism)" is notified to the video controller.
When the position of the transfer roller ESP is shifted normally, the slide plate is placed to the standard position and all four colors' transfer rollers are returned
to be engaged for the "ETB cleaning "

The pick-up/feed system is to pick up and feed paper and it consists of various feed rollers and the driving system.
This printer has pick-up sources: the cassette and the multipurpose tray (hereafter MPT), and delivery sources: the face-down tray and the duplexing unit.
The MPT paper sensor (SR707) detects the paper presence in the MPT, and the cassette paper sensor (SR709) detects the paper presence in the cassette.
The feed rollers in this printer are driven according as the DC controller controls the feed motor (M4), ETB motor (M5), drum motors (M6, M7, M8, and M9), and
pick-up solenoids for MPT and cassette (SL5012, SL5013).
There are the MPT paper position sensor (SR708), top of page sensor (SR710), paper warp sensor (SR6001), and fixing paper sensor (SR6005) on the paper transport
path to detect arrival and passage of paper.
There are other sensors, such as fixing pressure release sensor (SR705), one-sided paper sensor (SR714), and cassette presence switch (SW2).
The duplexing solenoid (SL10) is controlled and the top of page sensor (SR710) is used for duplexing reverse operation of second side printing under the duplexing
print.
The outline diagram about each motor, the solenoid, and the sensor is shown below.
