HP Designjet 1000 Series Printers - TWI: System Error 06030A

Document number: BPP90069

Last updated: 17-Mar-2003

Minimum skill level: 2

The line sensor on the Carriage cannot find the mark encoder located on the left side of the drive roller. The main causes for this issue are a dirty mark encoder or malfunctioning line sensor on the Carriage. Follow the instructions listed below to accurately troubleshoot the issue, replace the appropriate parts, and perform the necessary calibrations.

Part description	Models - C6074A, C6075A, C6074B, C6075B
Carriage Assembly (Required)	C6074-60388
Rear Bushing (Required)	C4704-40084
Spring (Required)	C1633-80014
Trailing Cable (Required)	C6074-60418
Electronics Module Fuse (Required)	C6074-60467
Encoder Strip (Required)	C6072-60197
Lubricant (Required)	C6071-60177

NOTE: If the printer is installed on a Multi-Roll feeder accessory, some Multi-Roll disassembly is required to gain access to the printer. Instructions for Multi-Roll disassembly are listed at the bottom of this document for reference.

NOTE: The fuse being sent should be used if a poor Trailing cable connection or a shorted Trailing cable blows the fuse on the Electronics module. Make sure to properly connect the Trailing cable or replace a shorted Trailing cable before installing the new fuse.

If any of the troubleshooting steps listed below solve the problem, attempt to verify printer functionality by printing several internal prints. If functionality is verified, no additional parts should be replaced.

NOTE: If the error code appears during initialization press the Enter key to allow printer to complete the rest of the initializing process.

1. Turn the printer off.

2. Clean the line sensor on the Carriage as described below:

   1. Turn the printer off.

   2. Open the Printhead cleaner door and pull the Printhead cleaner tray towards the front of the printer until it stops.

   3. Remove all of the Printhead cleaners. When all cleaners are removed, the tray should be pushed back into the printer far enough to access the underside of the Carriage (the carriage may then be moved to gain better access beneath the line sensor).

   4. Clean the Line sensor on the Carriage using a lint-free cloth dampened with water.

3. Turn the printer on.

4. If no error appears, attempt to verify functionality.

5. If the error persists, continue with the remaining steps.

6. Clean the Mark encoder as instructed below:

   1. Open the Top cover.

   2. If the Mark encoder is visible (left-hand side of Drive roller) clean using a lint-free cloth dampened with water. Following Mark encoder cleaning continue with step 7.

   3. If the Mark encoder is not visible for cleaning, activate the top cover sensor with a folded piece of paper or a pen, then access the Printer Setup Options (Icon of printer on front panel display).

   4. Using the Arrow keys, scroll to Utilities and press Enter.

   5. Simultaneously press the Up Arrow key and the Enter key.

   6. Scroll to Service Utilities and press Enter.

   7. Scroll to 5. Overdrive Cleaning and press Enter.

   8. Use the Arrow keys to move the Drive roller, select Stop when the Mark encoder is visible.

   9. Clean the Mark encoder using a lint-free cloth dampened with water.

   10. Continue with the remaining steps.

7. Turn the printer off then on, and attempt to verify functionality. If the problem persists, continue with the remaining steps.

8. Clean the encoder strip with a lint free cloth dampened with water. Replace the encoder strip if visibly damaged (refer to pg. 8-34 of the 1000 Series Service Manual).

   NOTE: If removal and installation instructions are needed for reference during any repairs performed, refer to the 1000 Series Service Manual available on the Computer Care Web site for review or download.

9. Clean and lubricate the Carriage rail.

10. Check for obstructions in the Carriage path:

    1. Remove the left end cover.

    2. Slowly slide the Carriage all the way over to the left end of the printer, checking for obstructions along the way. Make sure the trailing cable is not interfering with Carriage movement. Adjust as needed.

    3. Check the operation of the cutter and tensioner assemblies, and replace as needed.

11. Close the window.

12. Turn the printer on and check for error during initialization.

13. If no error appears during initialization, perform a Line Sensor Calibration (listed below). Following successful calibration, verify printer functionality (if problems persist following the calibration, continue with step 16).

14. If the error re-appears, press Enter to continue with initialization process.

15. Perform a Service Station calibration (listed below). Following a successful Service Station calibration attempt to verify functionality.

16. If the error continues, replace the Carriage and Trailing cable (refer to pg. 8-44, 8-39 of the 1000 Series Service Manual).

17. Following replacement, perform the following calibrations: 2. Line Sensor, 3. Service Station, 4. Roller Mark Position, 6. Color to Color, 8. Pen Alignment, and the Carriage Height Calibration (listed below).

NOTE: Printer menu mode must be set to Full to access the Service Tests submenu. To verify, at the Ready prompt, scroll to the PRINTER SETUP icon, and press Enter. Use the Arrow keys to scroll to the Utilities menu and press Enter. Using the Arrow keys scroll to Menu Mode =. Select Full (if needed) and press the Back key to return to the main menu.

1. At the Ready prompt, scroll to the PRINTER SETUP icon and press Enter.

2. Use the Arrow keys to scroll to the Utilities menu, and press Enter.

3. Once in Utilities menu, press the Up Arrow key and the Enter key together. You will now be in the Service Tools menu.

4. Scroll to Service Calibrations menu and press Enter.

5. Scroll to the needed service calibration and press Enter.

6. Follow instructions displayed on the front-panel to complete the selected calibration.

7. When calibration is finished, stay in Service Mode to perform any additional calibrations (if required).

8. When all required calibrations are complete, return to the main Status display using the Back key.

9. Turn the printer off.

10. Turn the printer on, and attempt to verify functionality.

Only remove the corresponding side cover of the Multi-Roll that requires maintenance. For example, only remove the right side cover of Multi-Roll if only the right end cover of the printer requires removal to complete the necessary service. Follow the steps listed below to gain access to the printer to complete the necessary service.

NOTE: Only ONE CE needs to be dispatched to perform service on a 1000 Series printer attached to a Multi-Roll feeder.

WARNING: Turn both the printer and the Multi-Roll feeder Off and disconnect them from the power source prior to performing any maintenance.

1. Open the left door of the Multi-Roll feeder.

2. Loosen the two screws that secure the left door to the Multi-Roll feeder.

   Figure 1:Left door screws.

   

3. Remove the left door.

   CAUTION: Be careful when removing the door not to break it.

4. Remove the two star screws (Orange) that secure the Front top-cover to the Multi-Roll feeder.

   Figure 2:Front top-cover screws needing removed.

   

5. Remove the Multi-Roll feeder top cover.

6. Remove six T-20 screws that secure the left Side cover to the Multi-Roll feeder from the front.

   Figure 3:Screws securing the front left-side cover.

   

7. Remove the seven T-20 screws that secure the left side cover to the Multi-Roll feeder from the rear.

   Figure 4:Screws securing the rear left-side cover.

   

8. Remove the left side cover.

   Figure 5:Removing the left side cover.

   

WARNING: Turn both the printer and the Multi-Roll feeder off and disconnect them from the power source prior to performing any maintenance.

1. Remove the Right door and Front top cover from the Multi-Roll feeder (follow steps 1 through 5 of the previous section and remove the right door instead of the left).

2. Remove Six T-20 screws that secure the right side cover to the Multi-Roll feeder from the front.

   Figure 6:Screws securing front right-side panel.

   

3. Remove nine T-20 screws that secure the right side cover to the Multi-Roll feeder from the rear.

   Figure 7:Screws securing rear right-side cover.

   

4. Open the Rear Top cover.
