General Troubleshooting
Engine Test Print (SFP)
The Engine (Pattern IOT) test print isolates printer hardware problems to either
the MCU or Image Processor Board by eliminating the need for image data
transfer between the two. The printer requires no Image Processor Board circuitry
to produce the image.
Use this procedure to print an Engine Test print by shorting two contacts on the
MCU Board.
1. Turn the printer Off.
2. Open the Front Cover.
3. Remove the Top Cover (page 8-15).
4. Remove the Right Side Cover (page 8-17).
5. Remove the Left Side Cover (page 8-18).
6. Remove the Rear Tray Cover (page 8-19).
7. Remove the Rear Cover (page 8-20).
8. Disconnect P/J401 and P/J29 from the IP Board.
9. Disconnect P/J10 and P/J11 from the MCU Board.
