System Error Codes NOTE Introduction System error codes are hexa-decimal based numbers generally caused by internal system errors. 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. Continuable and Non-Continuable Error Codes Some of the Error Codes are continuable, which means you can press Enter on the front-panel and continue working with the Printer. Non-Continuable Error Codes do not allow you to continue working with the Printer, in this case power the Printer OFF and ON again and see if the System Error disappears. If the Error Code reappears, then the Printer requires an on-site visit in order to resolve the problem. Even though the customer can continue working with a Continuable Error Code, an on-site visit should still be planned to troubleshoot the problem. System Error Codes - Explanation System Error Codes consist of 4 digits which explain which component/system is failing and what action should be taken to resolve the problem. The following table explains the first 2 digits of the System Error Code: Code 01 02 03 04 05 06 07 08 11 Component/System Main PCA/Electronics Module Carriage/Carriage PCA Power Supply Unit Network Card Formatter Hard Disk Drive Interconnect PCA Front Panel Trailing Cable 2-2 HP DesignJets 500 and 800 Series Printers Service Manual
