Dirt inside the machine may affect printing results. Perform care and cleaning to the machine first. Maintenance and Inspections
Are you using appropriate paper?
Check the supported paper types and replace with an appropriate type. Also, set the paper size and type correctly.
Do you print data without margins?
This symptom occurs if a margin is set to none in the printer driver. A margin of 5 mm or less around the edge of paper or 10 mm or less around the edge of envelopes is not printable with the machine. Make sure to have margins around the document to print.
