Error Messages The following error messages require operator intervention; they are listed numerically. 02 TONER LOW Meaning: The toner in the printer cartridge is low. Action:   Check the next several pages of printed output.   If the print quality is
acceptable, press the Continue/Enter key to clear the message.   Ensure that a
new toner cartridge is available.   When the print quality becomes unacceptable,
install the new toner cartridge (see “Changing the Toner Cartridge” on page  92). Note:   If the print quality is unacceptable and you do not have a new toner
cartridge, remove the old cartridge from the printer and gently rock it back and
forth.   This may temporarily improve the print quality of the old cartridge. 04 TONER CART MISSING Meaning:   The toner cartridge is either missing or is not in place. Action: Open the printer and make sure the toner cartridge is seated correctly.   If
you have not installed a toner cartridge, do so now. 06 COVER OPEN Meaning: A cover is open. Action: Close the cover that is open. 11 LOAD paper_size IN tray Meaning:   The tray is out of paper or it contains the wrong size paper.   The
message identifies the size of paper (paper_size) and the tray (tray) that needs
paper. Action:   If the tray is empty, refill it.   The printer resumes printing on its own. If the printer contains the wrong size paper, you have two choices: to use the
current paper size, press the Continue/Enter key; otherwise, load the correct
paper size into the bin. Note:   If the problem persists, check the end guide adjustment in the paper tray.
See “Loading Paper into the 250-Sheet Paper Tray (Tray 1)” on page  23. 12 LOAD paper_size IN MANUAL Meaning: The auxiliary tray requires paper. The message indicates the required
size (paper_size). Action: Place another sheet of paper or other media in the auxiliary tray and press
