Anyone else dealing with returning J66-23 codes/calls on the DF-621 ADF we have cleaned the reflective photo sensor on the lower portion, and it's associated black felt.

Thank You !!

Did battle yesterday on DF-621 constant 66-23s again....

Turns out the DEEP hole for the upper reflective, had just enough paper dust present to cause constant 66-23 jamming each attempt.

Thanks for the help all !!!
