218 Troubleshooting
Color Unmatched
The colors on your computer do not match the colors output by 
the printer. The version of the driver that is installed and the 
model of the printer’s color screen are not compatible. Install the 
latest version of the printer driver and printer firmware. For 
details, contact your dealer or service agent.
Duplex Mem Overflow
There is not enough memory for duplex printing. The printer 
prints only on the front and ejects the paper. To clear this error, 
follow the instructions below.
If Off is selected as the Auto Cont setting on the control panel’s 
Setup Menu, press the N Start/Stop button to print on the back of 
the next sheet, or press the + Cancel Job button to cancel the print 
job.
If On is selected as the Auto Cont setting on the control panel’s 
Setup Menu, printing continues automatically after a certain 
period of time.
Form Feed
The printer is ejecting paper due to a user request. This message 
appears when pressing the N Start/Stop button once to take the 
printer offline, then holding down the N Start/Stop button for 
more than 2 seconds in order not to receive a form feed command.
Image Optimum
There is insufficient memory to print the page at the specified 
print quality. The printer automatically lowers the print quality 
so that it can continue printing. If the quality of the printout is not 
acceptable, try simplifying the page by limiting the number of 
graphics or reducing the number and size of fonts.
To clear this error, select Clear Warning from the control panel’s 
Reset Menu. See “How to access the control panel menus” on page 
247 for instructions.
