Service Codes Introduction

System error codes consist of four digits that explain which component or system is failing and what action should be taken to correct the problem. The information below provides an explanation of the error and the recommended action to be taken.

Continuable and non-continuable error codes

Some error codes are continuable, which means that it is possible to press the Enter key on the front panel and to continue working with the printer. Non-continuable error codes do not allow work with the printer to continue.
