JCM Part No . 960 - 000053R _ Rev . 6 © 2007, JCM - American Corporation 6 - 1 8 Section 6 AD - 02™ Retrievable Bill Validator Programming and Testing Repeat the cleaning process as needed until the Transport path is free of contaminants . C LEANING THE B ULK N OTE F EEDER Figure 6 - 49 indicates the Bulk Note Feeder Sensor and Roller locations requiring periodic cleaning . C LEANING THE V ALIDATOR Figure 6 - 50 indicates the location of the Validator’s Sensors, Rollers, Belts and Pulleys requiring periodic cleaning . Each Validator contact area requires the following different cleaning attention: •   Optical Sensors — Just wipe dust off using a cotton cloth or swab •   Magnetic Sensors — Just wipe dust off using a cotton cloth or swab •   Rubber Rollers — Wipe dust off by using a cotton cloth or swab soaked in approved cleaning solution •   Resin Rollers — Wipe dust off using a cotton cloth or swab •   O - Ring Pulley — Wipe dust off by using a cotton cloth or swab soaked in approved cleaning solution •   Belts — Wipe dust off using a cotton cloth or swab soaked in a mild detergent based water solution . Cleaning Other Bill Path Sensors To clean other sensor areas in the AD - 02, refer to the Figure 6 - 51 Sensor locator diagrams, their associated descriptions listed in Table 6 - 7 and proceed as follows: 1 . Clean the indicated sensors using a source of compressed air . In particular, periodic cleaning is required for the Validation Unit Sensor and Counting Sensors Figure 6 - 49 Bulk Note Feeder Sensors & Rollers Right Rollers Sensor Left Sensor Figure 6 - 50 Validator Sensors, Rollers, Belts & O - ring Pulley Locations O - Ring Pulley Left Sensors Center Optical Sensor Left Rubber Roller Rubber Roller Rollers Resin Right Rollers Resin Magnetic Belts Rubber Roller Rubber Roller Sensors Optical Right Sensors Optical Magnetic Sensor NOTE: If the Validator’s acceptance rate does not improve after cleaning, contact your JCM Technical Support representative .
