System Error Codes

Introduction

The following pages contain a list of system error codes and their respective descriptions and recommended corrective actions. Only try one recommended action at a time and check if the error code has disappeared.

Since the front panel can only display graphics, the error code needs to be determined by counting the bars on the front panel (as shown below).

System Error Codes

Errors and Warnings

Error Codes will normally be displayed directly on the front panel (but can also be seen on the Information Page) and will require some kind of intervention to resolve the problem. Warnings will not be displayed on the front panel, but will instead only appear on the Information Page, therefore allowing the user to continue operating the printer without the need of an intervention.

Corrective Action: Using the System Maintenance Tool, perform Color Calibration for Photo Satin Paper and the selected print quality setting.

System Error:	94:04
Problem	Firmware Error (during color calibration).
Description:

Corrective Action: Try the following:

Unplug the power cable from the printer and wait a few seconds. Plug in the power cable again and check if the Error Code has disappeared.

If the Error Code reappears, check for a new Firmware release.

System Error:	94:08
Problem	Color Calibration Warning - Color Calibration not cancelled but Color
Description:	Calibration values are likely to be incorrect.

Corrective Action: Try the Color Calibration again, but this time using a different type of media (preferably HP media).

System Error:	94:10
Problem	Color Calibration Failure - Color Calibration cancelled.
Description:

Corrective Action: Try the following:

Unplug the power cable from the printer and wait a few seconds. Plug in the power cable again and try the Color Calibration again.

If this error code appears again, check the Color Calibration print:

–If the Color Calibration was printed correctly without any print defects, then check that the media is moving freely (backwards and forwards) while the printer is scanning it.

–If the Color Calibration was printed incorrectly, with some print defects,

Startup track mode

Introduction

The startup track mode is designed to enable you to identify a failing subsystems while the printer is initializing. Startup track mode provides a specific indication of which particular subsystem is failing. This mode is not intended for use by end-users.

Initializing the printer in Startup track mode

To initialize the printer in Startup track mode:

1Hold the ’Continue’ button while connecting the printer to the power supply.

2During the initialization of the printer, the front panel will display a range of code numbers in the form of squares, these code numbers added together represent the various subsystems about to be initialized.

3Once the printer comes to initializing the failing subsystem, the front panel will hang, and all that will be displayed is the failing subsystem.

Interpreting the numbered code system

While the printer is initializing, the front panel will display a sequence of squares in the last two columns. Each position in the last two columns represents a number, all the numbers represented are shown below. To find the failing subsystem, add the numbers together that have a square and refer to the list of numbers with their associated subsystems page 20.

In the example below the printer is initializing and the front panel has stopped and is displaying squares in positions 16, 32, 64 and 4. Add these four values together and you get 116, refer to the list on page 20, and we can see the failing subsystem is the Trailing Cable.

If the display reaches 191, you will need to turn On the printer from the power button. If all the subsystems pass the initialization, the printer will initialize normally and go to the ready status.
