select the Paper Type that suits the paper in your multi-purpose sheet

Printed pages are smeared.

Rough surfaces or thick media can cause “smeared pages”-OR-“the

 

 

 

toner to smear”. Make sure you select the correct Paper Type that

 

 

 

suits the paper in your multi-purpose sheet feeder. (See Paper Type,

 

 

 

page 61 and Media Type, page 68.)

 

 

 

 

Printouts are too dark or light

Adjust the print conditions by setting the Print Density function. It has been

 

 

 

factory set to the middle position. (See Setting the Print Density, page 23.)

 

 

 

 

Printed pages contain white stripes.

You may fix this by wiping the scanner windows with a clean soft

 

 

 

cloth. (See Regular Maintenance, page 127 and Cleaning the Drum
