Hello,
We are getting SC553 when printing envelopes with two different fusers(rebuilt with sleeve & thermistors) only happens when media type is cardstock or envelope is selected for printing thru bypass. Machine will copy envelopes on thick modes with no errors.
I do have another fuser that works fine in the machine? Rechecked all connections etc. on the rebuilt units. Machine does not try to feed the envelope just starts running then pops the code? Any help would be appreciated.
Best regards
