REPLACING A SENSOR

TX 7B RX 8A Ref 4.0

Use these instructions for 9835 printers version 5.0 or earlier. All of the harnesses are identified with part numbers and must be attached to the sensor board (118699). Follow the same cable routing that was used for the original system.

To replace a sensor:

1.Remove the ferrite noise filter from the

old reflective object harness (118704) and install it on the new harness (118704).

NOTE: Be sure the Reflective Object Sensor is located in the middle of the sensor housing (117990)

2.Locate the label that is applied to the top of the sensor board (118699) and make note of the Trans and REFL HEX values.

These values must be entered using Sendfile V 2.15. You must convert the HEX value to decimal using

Microsoft® Windows® Scientific Calculator.

3.Once the parts have been installed you will need to power up the printer in Diagnostic Mode. Set SW-3 on lower

bank of switches to the “ON” position and turn on the 9835 printer.

4.Start Sendfile and go to the Diagnostics section. On the left side of the screen you will see a command that says: Reset 98xx DAC values.

5.Press "R" to enter this function.

6.A pop up menu appears. This is where the Transmissive (Trans) and Reflective (REFL) values recorded from the board will be entered.

7.Press 2 followed by the 3-digit decimal value converted using the scientific calculator.
