copying. See “Generation Copy”, 
Copy/Document Server Reference.
Copies are too light. Image density is too light. Adjust the image density. See “Adjust-
ing Copy Image Density”, Copy/Docu-
ment Server Reference.
Copies are too light. A light copy may result 
when you use damp or 
rough grain paper.Use the recommended paper. also, use 
paper that has been stored in the rec-
ommended temperature and humidity 
condition. See “Copy Paper”, About 
This Machine.

Copies are blank. The original is not set cor-
rectly.When using the exposure glass, face the 
originals down. When using the ADF, 
face them up.
A moiré pattern is pro-
duced on copies.Your original has a dot 
pattern image or many 
lines.Place the original on the exposure glass 
at a slight angle.
Black spots appear on the 
copy of a photographic 
print.Because of high humidi-
ty, the photographic print 
has stuck to the exposure 
glass.Place the print on the exposure glass in 
either of the following ways:
 Place an OHP transparency on the 
exposure glass, and then place the 
print on top of the OHP transparen-
cy.
 Place the print on the exposure 
glass, and then place two or three 
sheets of white paper on top of it.

Misfeeds occur frequently.The number of sheets 
loaded exceeds the capac-
ity of the machine.Load paper only as high as the upper 
limit markings on the side fence of the 
paper tray or bypass tray. See “Copy 
Paper”, About This Machine.
Misfeeds occur frequently.The paper trays side 
fence is set too tightly.Push the side fence lightly, and then re-
set it. Also, we recommend you set at 
least 20 sheets of thick paper.

ment Server Reference.
You cannot combine sev-
eral functions.Selected functions cannot 
be used together.Check the combination of functions 
and make the settings again. See “Func-
tion Compatibility”, Copy/Document 
Server Reference.
When sorting, the pages 
are divided into two 
blocks.The memory became full 
in the middle of sorting 
and the pages were deliv-
ered in two blocks.You can interrupt copying when the 
memory becomes full. See “Memory 
Full Auto Scan Restart”, General Set-
tings Guide.

during printing with sta-
pling.When you stop printing 
while using the staple 
function, paper not sta-
pled during printing may 
be left in the staple unit.Press the {Clear Modes} key and cancel 
copy settings, including stapling.
The copy is grayed out or 
a text pattern appears in 
the background of the 
copy.You have copied a copy-
guarded document pro-
tected from unauthorized 
copying.Check the document. See “Using [Data 
Security for Copying]”, Printer Reference.
Images are skewed. The side fences in the pa-
per feed tray is not 
locked.Make sure the paper guide is locked.
