System Error Codes System Error: System Error 119x: Head Relay Variable Supply Error Problem Description: Output voltages of the Head Relay Board are abnormal. Corrective Action: Try the following: „ Check whether 36V is supplied to the Main PCA. If not, then: – Replace Power Supply Unit ⇒ Page 8-43 . „ Preset the Head Relay Board Voltage from the Diagnostic Menu. Use a circuit tester to check the voltages of the channels that have an error . „ If the voltage is supplied, it means that the voltage check circuit is defective. Replace the Main PCA ⇒ Page 8-35 . „ If the voltage is not supplied, replace the Head Relay Board ⇒ Page 8-40 .
„ There is a possibility of a short circuit off the Head Relay Board output line. Perform a short circuit test on the Main PCA. „ Make sure the Carriage Trailing Cable is connected correctly and is not damaged. – Make sure that the Rear Cover is closed. System Error: System Error 11Ax: NVRAM Error Problem Description: The data in the NVRAM is incorrect. Corrective Action: Try the following: „ Switch the Printer OFF and ON again and check if the error still appears. „ If the error continues, skip the Power-ON Self-Diagnostic by keeping the Cancel Key pressed and powering ON the Printer. Perform NVRAM Initialization ( ⇒ Page 4-47 ) and then perform Restore Calibs ( ⇒ Page 4-48 ).
Switch the Printer OFF and ON again and check if the error still appears. „ If the error continues, restore the Printer to defaults settings. Switch the Printer OFF and ON again and check if the error still appears. „ Check whether the NVRAM is mounted on the Main PCA correctly. If necessary, replace the NVRAM ⇒ Page 8-39 . „ If the error continues, replace the Main PCA ⇒ Page 8-35 . System Error: System Error 11C0: Cap Position Error Problem Description: The Carriage position sensors have detected more than a 2mm gap during the capping operation. Corrective Action: Try the following: „ Make sure that the Encoder Strip is not stained.
„ Make sure that the Encoder Sensor is mounted correctly and that the cable is connected correctly. „ Make sure that the Trailing Cable is connected correctly. „ Replace the Carriage PCA ⇒ Page 8-91 . „ If the error continues, replace the Main PCA ⇒ Page 8-35 . 2-10 HP Designjet 9000s Series Printer Service Manual
