11. In some cases your NEW FFC cables will not be “PRE-FOLDED” to fit yout machine. If your
cables are “PRE-FOLDED” move on to step 12. If they ARE NOT “PRE-FOLDED” follow the
steps below.
Mark your EXISTING cables on the print head end. (Indicated below 1-J) ,then follow each cable to the
CR BOARD and mark it the with corresponding marks on that end. (Indicated below 1-K)
Then tape the EXISTING cables together (in this example I am using paper clips to hold the cables together)
Remove the cables from the CR BOARD and use them as a template to fold your new cables.

The fold doesn’t have to be an EXACT match, the
main goal is too insure that the cables are plugged in
correctly.
For example: The “1U” (SLOT 1 UPPER CABLE) is
plugged into the corresponding slot on the CR BOARD.
If the cables aren’t facing the right direction or the slot
on the head or CR BOARD are switched, the printer
will error upon start up.
12.Gently unplug your existing cables from the CR BOARD. Plug your new cables into
the CR BOARD. Be sure the teeth of the cables are facing correct way, start with slot 1.
