Check the ITU release lever for correct operation. The ITU release lever is the black
lever located on the left upper side frame above the ITU opening and can be seen by
opening and lowering the MPF assembly. When locked, the lever should be at the 6
o'clock position. When unlocked, it should be in a 3 o'clock position. Undue pressure
is not required to operate the lever.
Turn the printer off, insert the ITU, move the lever to the 6 o'clock position, and turn
the printer back on.
If this does not resolve, replace the ITU assembly. See
