HP Designjet 400 Series Printers - EEROM Model ID Configuration Procedure

	Configuration procedures
	Accuracy Calibration

Document number: BPP90082

Last updated: 12-May-2003

Minimum skill level: 2

The EEROM Model ID configuration is incorrect. This can happen if a pre-configured board is being reused, the current board is incorrectly configured, or the model ID is not configured. An incorrect model ID can also cause steady Align Media + Cartridges + Data LEDs (Steady EKL system error). Use the steps contained in this document to correctly configure the printer's model ID.

NOTE: Check for Color Upgrade on 430 printers. Upgrade may be an accessory. Refer to reseller for new upgrade or charge STREP.

Configuration procedures

1. Always print a Service Configuration, whenever possible, to view results.
2. Turn the printer off.
3. Remove the firmware/memory SIMM cover from the back of the printer.
4. Remove firmware ROM and any memory SIMM installed in the printer.
5. Remove the right end cover.
6. Disconnect the media motor encoder cable from main PCA (connector ENC X).
7. Turn the printer on while holding down the REPRINT key.
8. Press the MEDIA SOURCE and MEDIA TYPE keys at the same time to enter the deconfiguration mode. The Fast, Normal, and Best LEDs will light up.
9. Using a suitable tool, short-circuit pins 1 and 2 (the first two pins on the right) of the media motor encoder connector (ENC X). The Cartridges, Data, and Media LEDs should light up as you short-circuit the pins.
10. Once you have shorted the two pins, the Fast, Normal, and Best LEDs should light up again.
11. Press the CANCEL and MEDIA SOURCE keys at the same time to exit the deconfiguration mode.
12. Configure the Printer with the correct Model ID as follows:
1. HP Designjet 430 (Monochrome) printer: hold the MEDIA SOURCE key down and press the PRINT QUALITY + SETUP keys at the same time.
2. HP Designjet 450C (Color) printer: hold the MEDIA SOURCE key down and press the PRINT QUALITY + MEDIA TYPE keys at the same time.
3. HP Designjet 455CA printer: hold the MEDIA SOURCE key down and press the PRINT QUALITY + REPRINT keys at the same time.
4. HP Designjet 488CA printer: hold the FORM FEED key down and press the REPRINT + CANCEL keys at the same time.
13. Turn the printer off.
14. Reinstall the firmware ROM and memory SIMM (if applicable).
15. Close the SIMM cover.
16. Reconnect the media motor encoder cable to the main PCA (ENC X connector).
17. Turn the printer on.
18. After initializing, the Ready + Data + Media LEDs (steady DLM) will be On (error in X-axis calibration).
19. Perform an Accuracy calibration (listed below).
20. Press the CANCEL key and print the Service Configuration sheet to check if the printer has been correctly configured as a HP Designjet 430, 450C, 455CA, or 488CA.

NOTE: If the printer is still incorrectly configured, the Align Media + Cartridges + Data LEDs (Steady EKL) error code will be displayed on the front panel. Turn the printer off and perform the configuration procedure again, starting at Step 2.

Accuracy Calibration

1. Place a sheet of polyester film over the top of the printer for approximately 10 minutes to let it stabilize to the environmental conditions. Use a sheet approximately 24 x 36 inches, 61 x 91 cm (D-size). If sheet media is not available, roll media can be used if cut into a 24 X 36 inch sheet. When using polyester film, load it with the matte (dull) side down.

NOTE: If a polyester or matte film is not available, use HP Coated media when performing an Accuracy calibration.

2. Turn the printer off.
3. Press and hold in the MEDIA SOURCE key and turn the printer on (entering Service mode 2).
4. Set the Media Type on the front panel to Coated Paper.
5. Load the film with the matte (dull) side down, in portrait orientation.
6. When the Ready LED lights up press the REPRINT key.

NOTE: The Ready LED will begin to flash. Allow several minutes for the printer to complete the calibration print.

7. The printer will eject the sheet, and the Load Media LED will light up.
8. Unload the sheet from the printer.
9. Wait until the ink on the sheet is dry.
10. Cut the sheet along the dotted line and reload facedown into the printer in the direction indicated by the arrows on the calibration plot.

NOTE: The Ready LED will begin to flash. The printer takes less than 10 minutes to read the calibration sheet, calculate the calibration data, and save the data in the EEROM.

11. Unload the sheet from the printer.
12. The Accuracy calibration is now complete.
13. Turn the printer off then on, and verify printer functionality.
