ed temperature and humidity condi-
tion. See “Copy Paper”, About This 
Machine.

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. 
Paper does not output

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

In Image Repeat mode, 
the original image is not 
copied repeatedly.You selected copy paper 
the same size as the origi-
nals, or you did not select 
the proper reproduction 
ratio.Select copy paper larger than the origi-
nals or select the proper reproduction 
ratio.
Problem Cause Solution
The stamp position is 
wrong.The paper orientation is 
wrong.Check the paper orientation and stamp 
position.
Problem Cause Solution
You cannot make a book 
from Booklet or Maga-
zine mode by folding 
copies.You selected a setting 
(“Open to left”or “Open 
to right”) that does not 
match the orientation of 
originals.Change the setting. See “Orientation: 
Booklet, Magazine”, General Settings 
Guide.
When using Combine, 
parts of the image are not 
copied.You specified a reproduc-
tion ratio that does not 
match the sizes of your 
originals and copy paper.When you specify a reproduction ratio 
using Manual Paper Select mode, make 
sure that the ratio matches your origi-
nals and the copy paper. Select the cor-
rect reproduction ratio before using 
Combine mode.
Copies are not in correct 
order.You placed the originals 
in the incorrect order.When placing a stack of originals in the 
ADF, the last page should be on the bot-
tom.

When Memory is Full
This section explains likely causes of and possible solutions for problems related
to full memory.
❖Connect Copy
Note
❒If you set [Memory Full Auto Scan Restart] in User Tools to [On], even if the mem-
ory becomes full, the memory overflow message will not be displayed. The
machine will make copies of the scanned originals first, then automatically
proceed scanning and copying the remaining originals. In this case, the result-
ing sorted pages will not be sequential. See “Input / Output”, General Set-
tings Guide.
Message Cause Solution
Memory is full.
nn originals have 
been scanned.
Press [Print] to 
copy scanned 
originals. Do not 
remove remaining 
originals.
“n” in the message repre-
sents a changeable 
number.The scanned originals ex-
ceeds the number of pag-
es that can be stored in 
memory.Press [Print] to copy scanned originals 
and cancel the scanning data. Press 
[Stop] to cancel the scanning data and 
not copy.
Press [Continue] 
to scan and copy 
remaining origi-
nals.The machine checked if 
the remaining originals 
should be copied, after 
the scanned originals was 
printed.To continue copying, remove all copies, 
and then press [Resume Printing]. To 
stop copying, press [Stop].
Message Cause Solution
Sub-machine mem-
ory is full. Sub-
machine will be 
disconnected.The quantity of data ex-
ceeds the capacity of the 
sub-machine.Continue printing on the main machine.
