Fujitsu DL7400 User Manual

•  Use high-quality paper. Do not use paper that is wrinkled or 

curled at the edges. 

•  Do not use paper with staples or metal parts. 
•  Do not use paper with unpredictable variations in thickness, 

such as paper with partial multilayers, paper with embossed 
printing, and labels with the backing sheet exposed. 

•  Store paper in a clean, dry environment. 

•  Avoid using carbon-interleaved single sheets if possible. 

Printing tends to become misaligned on the bottom sheet. 

•  To ensure smoother feeding of paper-stapled, multipart forms, 

raise the rear stacker to support the forms. 

When printing envelopes, use the paper table or the manual feed slot of 
the cut sheet feeder. Note the following: 

•  When loading envelopes, make sure that the envelope flaps face 

forward. Otherwise, the envelopes may jam in the printer. 

•  Be careful to check operating conditions when using labels. 

Labels are sensitive to temperature and humidity. 

•  Only use labels mounted on continuous forms backing sheets. 

Do not print labels mounted on single sheet backing. Labels 
mounted on single sheet backing tend to slip and printing 
becomes crooked. 

•  Do not feed labels backwards using the LOAD button from the 

control panel. Jamming may occur. 

•  Do not use the printer tear-off feature when printing labels. If 

the labels are retracted, the backing may peel off and the labels 
may jam in the printer. 

•  Test-print labels before running a job. If jams occur, go into 

setup mode and 

- 

set the paper thickness control to manual mode and 

- 

set the paper thickness indicator to a wider position 
manually. 

If jamming problems continue, try a different type of label.
