Many nonsense 
characters are printed.
Is your computer or the machine in an 
unstable state?
If little free space remains in the memory or hard drive of 
your computer, or many jobs have been spooled on the 
machine and it has little free memory remaining, printed 
text may turn into nonsense characters. In this situation, 
cancel printing, restart your computer and the machine, 
and try printing again.
To cancel printing
Windows:
Double-click the printer icon that appears at the lower 
right of the task bar and click "Cancel All Documents" 
(or "Purge Print Documents") in the [Printer] menu.
Macintosh:
Double-click the name of the machine in the printer 
list, select the job that you wish to delete, and delete 
it. (In Mac OS 9.0 to 9.2.2, double-click the printer 
icon on the desktop, select the print job that you wish 
to delete, and delete it.)
At the machine:
Press the [JOB STATUS] key on the operation panel, 
touch the [Print Job] tab to change the screen, touch 
the key of the print job that you wish to delete, and 
touch the [Stop/Delete] key. A message appears to 
confirm the cancelation. Touch the [Yes] key.
If nonsense characters are still printed after restarting, 
ask your administrator to lengthen the timeout setting of 
"I/O Timeout" in the system settings (administrator).
➞ System Settings (Administrator) > "Printer Settings" > 
"Interface Settings" > "I/O Timeout"
If nonsense characters are still printed after taking the 
above measures, remove and then reinstall the printer 
driver.
