• Code: 52.02.01:12 ... 52.02.04:12
• Description: Drop-detector electronics X, 12 V power issue. Run subsystem diagnostic. Call your support representative if the diagnostic fails, or print quality is affected.
• Causes: a. Cabling connector problem b. Drop-detector PCA problem c. PSU problem (check whether this error happens to all drop-detector sensors)
• Remedy: 1. Run the drop-detector diagnostics. 2. Check the drop-detector PCA LEDs for troubleshooting. See Board name: Drop-detector PCA. 3. Replace the faulty part.

• Code: 52.03.00:01
• Description: Drop-detector encoder synchronization issue. Please run substsyem diagnostics. If problem persists, call your support representative. When performing drop detection, the printer performs synchronization with the linear encoder and the tail encoder located in the service-station motor in order to establish its position with respect to the dropdetector windows before performing the actual drop-detection action. This error indicates that this synchronization cannot be achieved as the readings from the two encoders do not match according to the movements performed.
• Causes: a. Intermittent failure due to used printheads that are not in good condition b. Drop-detector linear-encoder sensor dirty, disconnected, or failed c. The drop detection tray cannot move smoothly due to excessive friction or a mechanical problem d. Incorrect calibration of drop-detector system e. Failure in the service station motor, motor drive PCA, DD MUX PCAs, or connecting cables
• Remedy: 1. Check the nozzle health of the printheads. 2. Check the linear encoder strip in the service station. Make sure that the encoder strip is clean, correctly installed in the sensor, and correctly placed in its holders at each end. 3. Check the linear encoder sensor connection. Perform the drop-detector diagnostic test to check the linear encoder. If the test fails, replace the encoder system. 4. Grease the worm with a recommended grease, and make sure bushings are not damaged. 5. Check the functionality of the drop detector: œ Print the nozzle check. œ Cancel the drying time to save 10.15 minutes. œ If no failure is detected, there is no need to go further, the drop detector is working correctly, and the intermittent system error is due to the high usage of the printheads. 6. Perform a drop-detector calibration. 7. If there is no power (LEDs off), replace the e-box interconnect board. See E-box interconnect PCA. 8. Check the cable connections of the service-station system.

• Code: 52.04.00:02
• Description: Drop-detector movement test fault. Run subsystem diagnostic. Call your support representative if the diagnostic fails, or print quality is affected.
• Causes: a. Shuttle blocked b. Friction too high
• Remedy: 1. Use a screwdriver to ensure that the shuttle is not jammed against the structure. 2. Clean and oil the worm and rod sliders if necessary. 3. Run the backlash/elasticity diagnostic. 4. If the problem persists, replace the part.

• Code: 52.04.00:08
• Description: Drop-detector station jam. Reboot and run subsystem diagnostic. Call your support representative if the diagnostic fails, or print quality is affected.
• Causes: a. Shuttle blocked b. Friction too high
• Remedy: 1. Ensure with a screwdriver that the shuttle is not jammed against the structure. 2. Clean and oil the worm and rod sliders if necessary. 3. Run the backlash/elasticity diagnostic. 4. If the problem persists, replace the part.

• Code: 52.05.12:04
• Description: Motor driver PCA comm failure. Run subsystem diagnostic. If the problem persists, call your support representative.
• Causes: a. Service-station interconnect: main interconnect board cable disconnected, pin connection fault b. Power not reaching the service station PCA (5 V pin 19 and 12 V pin 2, GND 20&1) c. Service-station Interconnect fault d. Main interconnect board failed e. Engine PCI bBoard f. Firmware error/corruption
• Remedy: 1. Check the cable connections from the service-station interconnect board to the main interconnect board. Check for cable or pin damage. 2. Check that power is reaching the service-station interconnect (12 V and 5 V) (Power LEDs on). 3. If there is power (LEDs on) and no other failure is found, replace the service-station interconnect board and cable. 4. If there is no power (LEDs off), replace the main interconnect board. 5. Replace the main interconnect board. 6. Replace the service-station interconnect. 7. Replace the engine PCI board. 8. Reinstall the firmware and perform drop-detector calibrations. 9. Replace the hard disk drive.

• Description: Line sensor communication with EEPROM failure. Automatic substrate load and alignment disabled. Only manual options available. Contact your support representative.
• Causes: a. Line sensor disconnected b. Line sensor failed c. Sensor interconnect failed d. Carriage interconnect failed
• Remedy: 1. Check line sensor connections in the sensor interconnect. 2. Perform the line sensor check. See Table 5-12 Carriage sensors. 3. Replace the line sensor. See Line sensor. 4. Replace the carriage sensor box. 5. Replace the carriage interconnect board.
