Performing the initial troubleshooting check

Before you start the troubleshooting procedures, perform the following checks:

• With the power cord unplugged from the wall outlet, check that the cord is free from breakage, short-circuits, disconnected wires, or incorrect connections.
• Make sure the printer is properly grounded. Check the power cord ground terminal.
• Make sure the power supply line voltage is within 10% of the rated line voltage.
• Make sure the machine is securely installed on a level surface in a well-ventilated area.
• Make sure the room temperature is between 16 and 32¢XC (60 and 90¢XF) and that the relative humidity is between 20 and 80%.
• Avoid sites generating ammonia gas, high temperature, high humidity (near water faucets, kettles, humidifiers), cold spaces, near open flames, and dusty areas.
• Avoid sites exposed to direct sunlight.
• Make sure the paper is the recommended paper for this printer.
• Make a trial print with paper from a newly opened package, and check the result.

Power-on Reset (POR) sequence

When you turn the printer on, it performs a POR sequence.
Check for correct POR functioning of the base printer by observing the following:

1. The control panel indicator light turns on.
2. The control panel display turns on.
3. A splash screen appears on the display.
4. The cooling fan turns on.
5. The fuser heater turns on.
   Note: The fuser takes longer to warm up from a cold start than a warm start.
6. The main drive motor turns on.
7. The EP drive assembly drives the developer shaft located in the imaging unit.
8. The exit rollers turn.
9. The control panel indicator light blinks.
10. Ready appears on the display.

Using Safe Mode

Safe Mode lets the printer continue to operate in a special limited mode in which it attempts to continue offering as much functionality as possible despite known issues.

Warning—Potential Damage: Safe Mode is intended as a short-term workaround and should be used only in the case of a non-critical error when a print job must be completed before service can be arranged to repair the printer. The printer must be returned to standard operating mode before diagnostics can be run or full-function printing can continue.

You can enter Safe Mode in one of the following ways:

• Enable Safe Mode from the Configuration menu, and then POR the printer.
• Press the Stop and Back keys, and then POR the printer.

Return the printer to standard operating mode to service the printer and return to full-function printing.
