This error indicates that Drop Detector is not calibrated for all printheads. Possible causes are the Drop Detector or Service Station being previously replaced and the necessary calibrations not being performed. Other causes can include a faulty Drop Detector or in rare circumstances the Electronics module. Follow the steps listed below to determine the actual cause of the failure and to replace the appropriate parts.

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.

Parts required (part numbers are subject to change)

Part Description	Models - C6074A, C6075A	Models - C6074B, C6075B
Drop Detector (Required)	C6072-60400	C6072-60400
Electronics Module (Required)	C6072-69146	C6074-60283
Electronics Module Fuse (Required)	C6074-60467	C6074-60467
Trailing Cable (Optional) see note below	C6074-60418	C6074-60418
Maintenance Kit (Optional)	C6072-60395	C6072-60395

NOTE: If the printer is an "A" model,(i.e. - not a plus model) a Trailing cable must be sent with the rest of the parts listed.

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.

NOTE: If the system error code 0C0032 appeared after recent removal and replacement of an Electronics module (for `A' models) or Main PCA (for `B' models), then most likely, the calibrations backup has not been performed. If this is the case, proceed to Calibrations Backup and Pen Alignment sections listed below. If the system error persists, the service station calibration must be performed.

Inspect and Clean the Drop Detect Sensor

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.

1. Turn the printer off.
2. Open the top window and the right hand door.
3. On the right side of the printer, slowly slide the printhead cleaner tray out towards the front until it stops, to unlock the carriage assembly.
4. Slide the carriage to the left, to gain access to the Drop Detect Sensor.
5. Locate the Drop Detect Sensor spittoon, by looking for a black box just to the right of the white main drive roller gear. The Drop Detect Sensor spittoon is a rectangular opening (approximately ¼ inch x 1 inch) on top of the black box.
6. Inspect the rectangular opening for any obstructions such as torn pieces of paper or paper fibers.
7. Carefully clean around the top and top inner portion of the opening with a lint free cloth or coffee filter moistened with warm water.
8. After cleaning the Drop Detect Sensor opening, leave the carriage and printhead cleaner tray at its present position, close the top cover, close the right hand door, and turn the printer power back on and continue with the service station calibration below.

Service Station Calibration

1. Turn the printer on (if not already on).
2. Using the Arrow keys scroll to the Printer Setup Menu (Icon of printer in lower right side of the front panel display) and press Enter.
3. Scroll to Utilities and press Enter.
4. Press the Up Arrow key and the Enter key simultaneously (entering the service tools submenu).
5. Scroll to Service Calibrations and press Enter.
6. Scroll to 3. Service Station and press Enter.
7. Scroll to Accept and press Enter.
8. Follow all instructions on the printers front panel display.
9. When the Calibration has finished, print a Service Config Print to verify the calibration is within the stated limits (Printer Setup Menu, Utilities, Test Prints, Service Config).
10. If the Calibration passes, press the Top button several times, back to Ready and then turn power off to save the new calibration settings. Turn power back on after about 10 seconds and attempt to verify functionality.
11. If the error continues following the Calibration, replace Drop Detect Sensor (refer to pg. 8-10 of the service manual) and repeat the calibration.

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

12. If the error persists, replace the Electronics Module (refer to pg. 8-25 of the service manual for "A" models). (Refer to Supplement for Main PCA Replacement on "B" Models).

NOTE: If printer is an "A" model, replace the Trailing cable during the Electronics Module replacement. Refer to pg. 8-39 of the 1000 Series Service Manual for removal and replacement instructions.

13. Following replacement, turn the printer On and perform a Calibrations Backup and a Pen Alignment Calibration as listed below.

Calibrations backup

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 Utilities and press Enter. Scroll to Menu Mode =. Select Full (if needed), press Enter, and then press the back key to return to the main menu.

1. With the printer turned on, scroll to the Printer Setup Menu (Icon of printer in lower right side of the front panel display) and press Enter.
2. Scroll to the Utilities menu, and press Enter.
3. Simultaneously press the Up Arrow key and the Enter key.
4. Use the Arrow keys to scroll to Service Calibrations and press Enter.
5. Scroll to 7 Calibrations Backup and press Enter.
6. The printer will ask what has been replaced, select Electronics Module Repl, and press Enter.

NOTE: This procedure transfers the backup EEROM contents from the ink tube system to the EEROM on the newly installed electronics module (`A' models) or main PCA (`B' models).

7. Select Accept to continue the Calibrations Backup.
8. Press Enter when the Calibrations Backup is complete.
9. Continue with the Pen Alignment calibration listed below.

Pen alignment

1. In the Service Tools submenu scroll to the 8. Pen Alignment and press Enter.
2. Scroll to Accept and press Enter.
3. If paper is not loaded the printer will prompt for installation of paper, load as needed.

NOTE: Do NOT use Clear Film, Vellum or Natural Tracing paper when performing a Pen Alignment Calibration.

4. The printer will begin the Pen Alignment and display the time remaining to complete the calibration.
5. When the calibration is complete press Enter to continue.
6. Following the calibration, turn the printer off (saving the new calibration settings).
7. Wait at least 10 seconds and turn the printer on and verify functionality.

Multi-Roll feeder disassembly

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.

Removing the Multi-Roll feeder 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. Open the left door of the Multi-Roll feeder.
2. Loosen the two screws that secure the left door to the Multi-Roll feeder (see Figure 1).

Figure 1: Two screws that secure the left door to the Multi-Roll feeder.

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 (see Figure 2).
