• Description: Wiper output motor drive PCA communication failure. Run subsystem diagnostics. If the problem persists, call your support representative.
• Causes: a. Input motor drive PCA wiring/cabling problem b. Input motor drive PCA malfunction
• Remedy: 1. Run subsystem diagnostic. 2. Check connections and replace the PCA if necessary.

• Code: 48.00.00:01
• Description: PPS misalignment. Run diagnostics to recover PPS subsystem. If the problem persists, call HP service. The relative movement of one of the PPS modules with respect to the other is incorrect, which means that there is danger of a misalignment of the complete system. With this system error the system is protecting itself to prevent any possible damage. This system error can also happen when the distance between the homing position and the engage position is more than 7 mm.
• Causes: a. A trapped obstruction has damaged the power transmission and has broken the mechanical power chain. b. Moving down a homing sensor has been activated or the PPS switch has failed.
• Remedy: 1. Restart the printer. 2. Try to move the carriage beam to the normal position (from the Internal Print Server or Print Care). If it is still failing, reboot in diagnostic mode and perform the same operation from Print Care. 3. From the diagnostic mode, perform the switch diagnostic, testing the four different homing switches of the PPS. 4. If the carriage beam is misaligned, perform a manual alignment by removing the PPS motor and turning the PPS gear system until they are aligned. 5. Check that all the PPS supports are touching the scan axis. 6. Check whether any object is trapped between the scan axis and PPS support.

• Code: 48.01.01:01 ... 48.01.04:01
• Description: Servo shutdown PPS X not usable, but printing enabled/disabled depending on PPS value. If the problem persists, call your service representative. The meaning of X is: 1 = front right motor 2 = rear right motor 3 = rear left motor (IDS side) 4 = front left motor (IDS side) An error in the closed-loop control (servo control) of the PPS system has occurred. This error indicates that the PPS system is not moving as expected in closed-loop control. The servo-controlled movements consist of applying a specific PWM to a motor (a certain amount of energy) and receiving the feedback of an encoder about the actual movement of the motor after applying that specific PWM. Therefore, if after applying a specific PWM the encoder does not register the expected number of encoder counts (movement), the system will produce this error. Also if the PWM values come out of a certain range of values for the movement (i.e too high PWM to obtain a movement), this error is produced.
• Causes: a. PWM signal not supplied to motor. PWM generator (driver) failure, motor failure, cable failure, or disconnected. b. Encoder signals indicating the movement not registered. Encoder disconnected, encoder broken or failed, cable disconnected, or the electrical system receiving the encoder signal has failed. c. PWM is too high due to a mechanical failure. Mechanical system jammed, mechanical system broken or loose. d. PPS system fuse failure. Contact between mechanical system fuse and the motor module.
• Remedy: 1. Check the connection of PPS motor power cable and encoder cables. 2. Check that power is supplied to the encoder PCA (LED in the main interconnect). 3. With PPS in the high position, unscrew the X-Y bushing, and check that it can move smoothly through the column. The screwdriver needs to be long. 4. With the PPS in the low position, remove the bottom stopper to the PPS screw (may need to remove the left and right curing module). 5. Remove each PPS screw with a flat screwdriver and then grease the parts. Check that there are no obstructions. 6. If you find plastic or metal obstructions, you will have to remove the corresponding PPS motor assembly later to clean it too. 7. If the high friction error continues, swap the PPS screw from one to the other, and check whether the failure is following the PPS screw. 8. Check mechanical blocking status in the system fuse.

• Code: 48.01.01:02 ... 48.01.04:02
• Description: Movement X test fault. Subsystem disabled, but printing may be possible. If not, run diagnostics. If the problem still persists, call HP service. The meaning of X is: 1 = front right PPS movement test fault 2 = rear right PPS movement test fault 3 = rear left PPS movement test fault 4 = front left PPS movement test fault During start-up the printer produces an automatic check by making a small movement forwards and backwards to check the main system functionality (motor moves, encoder signals are received). This error is produced when this test fails. As the movement is very small, this error usually represents a critical error such as cables disconnected, motor failure, or a PCA fault.
• Causes: a. Cable connection failure b. Rotor of the motor blocked c. Motor failure/encoder d. Main interconnect board failure (for the right PPS systems) e. Remote controller failure (for the left PPS systems)
• Remedy: 1. Check correct connection of PPS motor power cable and encoder cables. 2. Check that the motor is not blocked by anything. 3. Perform the PPS motor diagnostic test. 4. Check mechanical blocking status in the mechanical movement limiter. 5. Replace the PPS motor together with the encoder system and cabling. 6. Replace the main interconnect board or the remote controller board, depending on which part has failed.

• Code: 48.02.01:40 ... 48.02.04:40
• Description: Servo X current out of range. Run diagnostics. If the problem still persists, call your service representative. The meaning of X is: 1 = front right PPS 2 = rear right PPS 3 = rear left PPS 4 = front left PPS
• Causes: a. Environmental conditions of PCA driver b. Overworking conditions of driver in the PCA c. Main interconnect board failure (for the right PPS systems). d. Remote controller failure (for the left PPS systems)
• Remedy: 1. Perform carriage beam system recovery. If this is not possible, recover the system manually by removing the motor and aligning the PPS by hand. 2. Perform PPS motor diagnostic test. 3. Check correct connection of PPS motor power cable and encoder cables. 4. Perform move to load position and check the average and maximum points of PWM values for high constant values of friction. If the values are very high, grease the PPS system. If the system error persists, replace the PPS motor mount unit that fails. 5. Replace the main interconnect board or the remote controller board, depending on the failing side. œ E-cabinet PPS control motors: main interconnect œ IDS PPS controlled motors: remote controller board

• Code: 48.05.3X:04
• Description: Driver motor PCA X communication issue. Run diagnostics to recover the PPS subsystem. If the problem persists, call your service representative.
• Causes: a. Cabling/wiring problem b. E-box problem c. Driver motor PCA problem
• Remedy: 1. Check wiring. 2. Run the subsystem diagnostics for PPS and e-box. Replace the faulty part.

• Code: 49.01.01:01, 49.01.02:01
• Description: X = 1 left, X=2 right bar aerosol removal fan fault detected. Run subsystem diagnostic to check them. If any fan doesn't work, call your support representative. The aerosol produced while printing may affect print quality. The aerosol can make other parts of the printer dirty, such as encoders or sensors, and create spontaneous failures. You should repair the problem as soon as possible.
• Causes: a. The carriage has two fan arrays with 5 fans to each array. The fans have a fault signal which is activated when the fan is powered but not rotating. Fans or arrays not connected will not display this error. b. One of the fans burned or failed. c. Carriage interconnect power fault (24 V) d. Carriage interconnect driver fault e. Data cable failure f. Printhead interconnect
• Remedy: 1. Check whether the fans are rotating when they are activated. Perform diagnostics. 2. Replace the aerosol fans. 3. Ensure 24 V are reaching the carriage interconnect: see the 24 V LED. 4. Replace the carriage interconnect. See Carriage interconnect PCA. 5. Swap fan array connections and perform the fan array diagnostic test to check which fan has failed. 6. Swap over data cables to confirm a data cable failure, replace the failed data cable. 7. If there is a signal failure, swap over the printhead interconnects 2 and 3, then recheck and confirm the error, and replace the faulty printhead interconnect.

• Code: 49.02.01:02
• Description: Left or right bar aerosol removal nozzle clog detected. Ensure that aerosol removal air inlet is clean.
• Causes: a. Nozzle/filter clogged b. Pressure sensor clogged/failing or connections damaged
• Remedy: 1. Check and clean the inlet. 2. Check and/or replace the filter. 3. Check the pressure sensor and its connections.
