f) Load the recommended print side correctly for the type of print media you are using.
g) Turn the print media over or around and try printing again to see if feeding improves (especially
thickness).
h) Check the print media type loaded in the source, and refill only one type of print media, if print
media types are mixed.
i) Refill a new ream of print media, if some reams are mixed.
j) Remove the top and bottom sheets of a ream before loading the print media.
k) Load a print media source only when it is empty.
4) If envelope misfeeds or multiple feeds occur, check and try the action below.
a) Remove the stack of envelops from the multiple purpose feeder (MPF).
b) Try to load the single envelope to the multiple purpose feeder (MPF).
5) If page breaks in unexpected places, check and try the action below.
a) Check the “Job Timeout” in the Basic Settings menu and increase the setting.
6) If a job prints from the wrong source or on the wrong print media, check and try the action below.
a) Check the “Paper Size” and “Paper Type” in the Tray Settings menu on the printer operator
panel and in the printer driver.
1.5.4 Print Media Guidelines
Print media is paper, transparencies, labels, envelopes, coated paper among others. Your printer
provides high-quality printing on a variety of print media. Selecting the appropriate print media for your
printer helps avoid printing troubles. This section describes how to select print media, how to care for
print media, and how to load the print media in the optional 250-sheet tray module or 550-sheet tray
module.
Paper
For the best print quality in color, use 75 g/m2 (20 lb.) xerographic, grain long paper. For the best print
quality in black and white, use 90 g/m2 (24 lb.) xerographic, grain long paper. Before buying large
quantities of any print media, Dell recommends trying a sample first.
When loading paper, identify the recommended print side on the paper package, and load the paper
accordingly. See "Loading Print Media in Optional Trays" and "Loading the Multipurpose Feeder" for
detailed loading instructions.
Paper Characteristics
The following paper characteristics affect print quality and reliability. Dell recommends that you follow
these guidelines when evaluating new paper stock.
Weight
The tray automatically feeds paper weights from 60 to 216 g/m2 (16 to 57.6 lb. bond) grain long. The
multipurpose feeder automatically feeds paper weights from 60 to 216 g/m2 (16 to 56 lb. bond) grain
long. Paper lighter than 60 g/m2 (16 lb.) might not be stiff enough to feed properly, and could cause
paper jams. For best performance, use 75 g/m2 (20 lb. bond) grain long paper.
Curl
Curl is the tendency of print media to curve at its edges. Excessive curl can cause paper feeding
problems. Curl usually occurs after the paper passes through the printer, where it is exposed to high
temperatures. Storing paper unwrapped in humid conditions, even in the paper tray, can contribute to
paper curling prior to printing and cause feeding problems.
Smoothness
The degree of paper smoothness directly affects print quality. If the paper is too rough, the toner does
not fuse to the paper properly, resulting in poor print quality. If the paper is too smooth, it can cause
paper feeding problems. Smoothness between 150 and 250 Sheffield points produces the best print
quality.
