Xerox Phaser 840 Document

Clean the printer’s internal paper path surfaces if your prints have stray ink marks 
on the front or the back.  

Always use clean sheets of paper to clean the paper path.  Do not reuse cleaning 
sheets.  High-grade, heavier papers, such as 120 g/m

2 

(32 lb.) bond, work best.

Load high-grade paper into the printer and make sure that the tray’s media 
selector switch is set to 

.  If your printer is configured with just the 

upper media tray, load that tray and set the media selection switch to 

.  

If you have installed one or two High-Capacity Paper Tray Assemblies, 
load either the upper tray or the lower tray.  The lower tray is the default; if 
you use the upper or middle paper tray, make sure that the printer’s 
default has been set.  Refer to “The Cleaning Page” on page 60 for details.
