1.0 Introduction
The Service Call Procedures section is used to identify a suspected problem. This section contains Call Flow, Initial Actions, Corrective Actions, and Final Actions. Call Flow illustrates the normal activities and flow of a service call. Initial Actions are used to gather information regarding the performance of the machine and prepare the product for servicing. Corrective Actions are used to verify the normal operation of the machine. In the Y/N (Yes/No) steps of the corrective actions, a Yes response will lead you to the next step. A No response will indicate the next step to perform or will direct you to a Repair Analysis Procedure (RAP). RAPs will provide the instructions to isolate the faulty part or provide a list of suspect parts, when isolation is not appropriate. Wire harnesses are not included in the repair actions and problems with loose connections or damaged harnesses should be isolated using visual inspection and the wiring data in section 7. Final Actions are used to evaluate the total operation of the system and to identify the actions required to complete the service call.

1.1 Machine Orientation
For servicing the DocuPrint N2025/N2825, all references to machine orientation are as illustrated in Figure 1.

1.3 Initial Actions
Initial Actions are used to gather information from the operator concerning problems at the local machine. Make note of symptoms, error messages, error codes or other information concerning the problem that the operator may provide. This information may help identify an intermittent or unusual problem. Procedure 1. 2. 3. 4. 5. 6. 7. 8. 9. Ensure that the power cord is connected to the wall outlet and to the machine. Check for paper or other objects in the paper path. Remove all paper from the output tray(s). The Rear Cover and Top Cover are closed. The paper is loaded correctly in the Paper Tray(s). Ask the operator to describe, or if possible, demonstrate the problem. If the problem is the result of incorrect operator action, refer the operator to the User documentation or to another customer support function. Refer to Section 2 if an error message is displayed. If possible, print the "Configuration Sheet". To print the Configuration Sheet, press and release [1] or [5] until "Print Menu" is displayed. Then press and release [2] or [6] until "Config Sheet" is displayed. Press Enter [4] to print the sheet. If the sheet is blank, go to IQ RAP 2.

Introduction
The Repair Analysis Procedures section is used to isolate and identify problems to a faulty component or subassembly. It contains the Introduction, display message table, error code table and the Repair Analysis Procedures (RAPs). Use the Display Messages and Error Codes tables when messages are displayed or error codes are printed in a report. The Repair Analysis Procedures (RAPs) are accessed from Section 1, system checks or additional checks. There are two types of RAPs: Status Indicator (SI) RAPs, contained in this section, and Image Quality (IQ) RAPs, located in Section 3. RAPs will normally isolate a problem to a specific component or subassembly, excluding the wire harnesses. In the Y/N (Yes/No) steps of the RAPs, a Yes/No response will either lead you to the next step or will indicate a corrective action. When the indicated corrective action has been completed, go to Section 1 and restart the System Check to verify that the problem has been corrected.

Measurements
Power and signal grounds are connected to frame ground, therefore all circuit troubleshooting can be performed using the metal frame (chassis) as the grounding point. If more information is needed to locate connectors or test points, refer to section 7. Unless otherwise specified, the following voltage tolerances are used within this section: Table 1 Table 1 Voltage Measurements Stated +3.3 VDC +5.0 VDC +24.0 VDC 0.0 VDC Measured +3.0 to 3.6 VDC +4.8 to +5.2 VDC +21.6 to +26.4 VDC Less than +0.5 VDC
