6. Engineer Training TN 59 Ink Management Solution TJ8300 / TJ8500 Confidential 6 Weigh Controller  Located on the right hand side inside the CCB Box.  Stand alone controller that can measure 8 weights.  Supplied with 12VDC for the controller operation. The board produces 5VDC.  Communicates with the computer’s COM1 via RS422 port (ACB).CCB Board WEIGH CONTROLLER.  Accuracy weighing of ±50 gram.

8. Engineer Training TN 59 Ink Management Solution TJ8300 / TJ8500 Confidential 8 Load Cell (Weigh sensor)  There are 7-load cells in the system, six for each color and one for the waste container.  The waste system will stop automatically when the load cell reads 10L.  The load cell is based on the principle of a bridge resistor.  The changes of the resistance in the bridge resistors is transferred to the weigh controller.

10. Engineer Training TN 59 Ink Management Solution TJ8300 / TJ8500 Confidential 10 How to Calibrate the Weigh System The weigh system comes already calibrated in the integration stage. If there is a need to replace the Load Cell (Weigh sensor) or the Weigh controller at the customer’s site, calibrate the weigh system as described below.

11. Engineer Training TN 59 Ink Management Solution TJ8300 / TJ8500 Confidential 11 Step 1: Calibrate the Zero Weight  All load cells must be connected to the weigh board and the optional connection #8 must be with the short plug.  Verify that there are no ink containers on the load cell, or any other weighs.  Use KVM measuring tool (DC) to calibrate the zero weigh for all the colors, see WEIGH CONTROLLER HARDWARE ADJUSTMENTS shown below. Example:  For the cyan color (Channel 1), put the negative probe at the common test point TP_C, and the positive probe at the TP1 test point.  Use potentiometer R149 to calibrate the zero point.

12. Engineer Training TN 59 Ink Management Solution TJ8300 / TJ8500 Confidential 12 Step 2: Calibrate the Scale  In this calibration we are calibrating the relation between the weigh and the voltage.  Place a weight (5 or 10 liter ink container). The measured voltage (X) that we will need to obtain at the test point is related to the weigh (A) that we put on the load cell 12.5 KG = 2.5V X = A (Weigh) X 2.5 (V) / 12.5 (KG) Example:  The 5L ink containers weigh 5.2KG (Tested), the voltage needed to be calibrate at the potentiometer scale for all the Channels is 1.04V.

15. Engineer Training TN 59 Ink Management Solution TJ8300 / TJ8500 Confidential 15 Step 3: Software Calibration A.Check the Zero weight: 1.Remove all the weights or Ink tanks from their socket 2.In the RTRun software go to Tools > Color Box > Weight Calibration, and mark the Zero weight. 3.Push color-by-color Calibration tab and Save tab when done. 4.Push the Test tab and verify that you get 0.00 for all colors and waist. 5.Repeat above steps again if necessary.

16. Engineer Training TN 59 Ink Management Solution TJ8300 / TJ8500 Confidential 16 B.Check the Full weight: 1.Place all the Full ink containers in their sockets (10 lit.). 2.In the RTRun software Go to RTRun > Tools > Color Box > Weight Calibration a.Select the Full Weight option. b.In the Real Weight (gr) box, enter the actual (measured) weight of the ink container. c.Example: for a full 5-liter container, enter 5200, and for a full 10-iter container, enter 10400 (gr). Step 3: Software Calibration (cont.)

17. Engineer Training TN 59 Ink Management Solution TJ8300 / TJ8500 Confidential 17 B.Check the Full weight: 3.Push color-by-color the Calibration tab and Save tab when done. 4.Push the Test tab and verify that you get the correct weight – the same as you entered in the Real Weight box. 5.Repeat step B if necessary.
