Cannot print

17

Print processing on the compu-
ter has finished, but printing 
does not start.

Is there sufficient available com-
puter memory?

Perform a test printing to check 
whether printing is possible.
If test printing is successful, this 
indicates there are no problems 
on this machine or with the print-
er driver. In this case, remove the 
cause of memory shortage.
If test printing fails, resolve any 
problems that may be occurring 
in the machine or with the printer 
driver.
For the test printing procedure, 
refer to page 17-8.

If network connection is in place, 
is the printer controller connect-
ed to the network?

Check with the network adminis-
trator.

Is the machine in enhanced se-
curity mode?

Configure authentication set-
tings in enhanced security mode.
For details on authentication set-
tings in enhanced security mode, 
refer to the User’s Guide DVD.

Printing order is disturbed - a 
job sent later is printed before 
the preceding jobs.

Has an error occurred in this ma-
chine, for example, the paper has 
run out?

When [Job Priority Operation 
Settings] is enabled in the [Ad-
ministrator Settings] of the print-
er, only the jobs that are not 
experiencing problems are proc-
essed and those with any prob-
lem are held in queue.

Secure printing cannot be proc-
essed.

Is [Password Rules] set to [Ena-
ble] on this machine?

If [Password Rules] is set to [En-
able], set a password that satis-
fies the password rules.

Does the encryption passphrase 
match between the printer driver 
and the machine?

Specify the same encryption 
passphrase for this machine and 
the printer driver.
For the encryption passphrase 
setting procedure for the printer 
driver, refer to page 17-10

A file has disappeared after be-
ing saved in a User Box from a 
computer.

Is the setting for deleting files in a 
User Box configured on the ma-
chine?

Check the User Box settings for 
the machine. For information on 
configuring the setting to delete 
files in a User Box, refer to 
page 6-8.

Printing in user authentication or 
account track mode is not avail-
able.

Are the user name or account 
name, and password correct?

Enter the correct user name, ac-
count name and password.

Is the user authentication or ac-
count track enabled in the printer 
driver?

Enable user authentication or ac-
count track on the printer driver.
For the procedure for enabling 
user authentication and account 
track in the printer driver, refer to 
page 17-11.

Does the encryption passphrase 
match between the printer driver 
and the machine?

Specify the same encryption 
passphrase for this machine and 
the printer driver.
For the encryption passphrase 
setting procedure for the printer 
driver, refer to page 17-10

Is the entered user name or ac-
count name authorized?

Check that printing of the current 
user name/account name is per-
mitted?
For information on how to check 
the permitted functions, refer to 
page 8-3.
