Check to see if the tape placed at the opening of the toner
cartridge has been removed or not.
Check to see if the lens surface of the LED head is stained with
toner or paper chips.
Check to see if the LED head is properly installed in the LED
head holder. Also check to see if the right and left tension
springs are properly installed.
Check to see if the medium loaded in the printer is not
something particularly thick.
Ensure visually that the high-voltage terminal of the ID unit is
duly in contact with the contact ASSY (see Figure 7-3).
Draw out and insert the ID unit by hand repeatedly, and check to
see if it is normally lowered to its lowest position free from any
abnormal load. Not acceptable (NG) if the leading edge of a
sheet of paper inserted in between the drum and the belt can
readily be passed through.

cartridge with a new
one.
Close the lever of the
toner cartridge, and
peel off the tape from
the opening.
Clean the lens with the
LED head lens cleaner.
Correct the installation
properly.
Use the prescribed
paper.
Replace the ID unit or
modify the high-voltage
terminal. To use a new
ID unit on a trial basis,
use FUSE KEEP
MODE of the System
Maintenance Menu.
Check the U-grooves of
the side plates for any
trouble. If the trouble is
irreparable, replace the
printer.
