Detecting MFP problems

Troubleshooting checklist

●Ensure that all of the sheets in the document that is loaded into the ADF are of the same size and that the document does not exceed the maximum stack height for the ADF.

●Ensure that media that is loaded into the trays is from a freshly opened ream, is free of defects, and is installed correctly. Ensure that the paper guides are adjusted correctly.

●Verify that the MFP is using a dedicated circuit and is directly plugged into the outlet. (Do not use a power strip or extension cord.)
