2.3 Optical Sensor Control

B-300/B-308/B-500DN/B-508DN/B-310N/B-318N/B-510DN/B-518DN uses the optical sensor to control itself. The following describes the operating principles of optical sensor control.

 Control method To ensure accurate printing, each part must be controlled to make an adequate amount

(time) of movement. The optical sensors read the amount (time) of movements as follows to printer to control it for achieving accurate printing.

1. Rotates the motors for control of the printer, and transmits drive force to the each part via the gear or the timing belt.

2. The encoder reads the drive amount of each part from the scale one by one to printer to monitor that the part drives for an adequate amount (time).

 Controlled parts The following table lists where the optical sensor control is used.

method

 Operating principles The following describes the PF drive control as an example of the actual operation for

the optical sensor. The PF scale consists of light-passing and light-blocking portions on its surface, and

runs through the slit between the encoder’s light-emitting and light-receiving devices. While the printer is operating, the encoder always emits light from light-emitting device toward the light-receiving device, and the light-receiving device detects light when the light is transmitted through the light-passing portion of the scale, and does not detect light when the light is blocked by the light-blocking portion of the scale. According to the counts of light-detected and non detected times, the printer controls paper feed drive direction and amount. When the encoder cannot read light-emitting/blocking counts correctly due to the misalignment, broken or contaminated scale, paper jam, foreign object and increasing a load, the fatal error occurs and the printer stops. (The phenomenon and error details when the optical sensor is abnormal, see “Table

3-16. Optical Sensor Control Error (PF Control)” on page 62.)
