Using the Control Panel 195
EPSON AcuLaser C3800 User's Guide
Form Feed
The printer is ejecting paper due to a user request. This message appears when pressing 
the N Start/Stop button once to make the printer offline, then holding down the 
N Start/Stop button for more than 2 seconds in order not to receive form feed command.
Format Error ROM A
An unformatted ROM module has been inserted. 
To clear this error, either press the N Start/Stop button or turn off the printer and remove 
the ROM module, then reinstall the ROM module. If that fails to clear the error, contact your 
dealer.
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 165 for instructions.
Turn the Image Optimum setting off on the control panel’s Printing Menu if you do not want 
the printer to automatically lower the print quality to continue printing.
You may need to increase the amount of printer memory to be able to print at the desired 
print quality for your document. For more information on adding memory, see "Memory 
Module" on page 220.
Install Cassette 1
The paper tray of the standard paper cassette is not installed, or not installed properly. 
Install the paper cassette correctly to clear this error.
Install Fuser
There is no fuser unit installed or the fuser unit is not installed properly. Turn off the printer, 
then install the fuser unit if it is not installed. 
If a fuser unit is already installed, turn the printer off and reinstall the unit after it has cooled 
off (30 minutes). Then open the front cover. Remove the fuser unit, then reinstall it 
properly. Close the front cover. The error clears automatically if the fuser unit is properly 
installed. 
If the error is not cleared, the fuser unit is out of order. Replace it with a new fuser unit.
