Install TransferUnit
There is no transfer unit installed or the transfer unit is not
installed properly. Turn off the printer and install the transfer unit
if it is not installed.
If a transfer unit is already installed, turn off the printer, open
cover A, and remove the transfer unit. Then reinstall the unit
properly and close cover A. The error clears automatically if the
transfer unit is properly installed.
Install xxxx TnrCart
The indicated toner cartridges are not installed in the printer or
the protective tape has not been removed from a toner cartridge.
(The letters C, M, Y, or K appear in place of XXXX and indicate
the colors Cyan, Magenta, Yellow, and Black respectively.)
Install the indicated cartridges. See "Toner Cartridge" on page
181. If the protective tape has not been removed from a toner
cartridge, turn the toner cartridge knobs to the unlocked position
and then return to the locked position. Then remove the protective
tape from the toner cartridge. If that fails to clear the error, turn
the printer off and back on again.

the data left in the printer by pressing the Cancel Job button
after deleting the spool file in the driver.
