In the previous article published in the March 2019 issue on these decurler transports, we went as far as replacing the four little white gears on the front end of the assemblies. Now we’ll take the disassembly a bit further and see how to replace the assembly’s upper and lower foam rollers, as well as some of the other smaller parts.
In the parts book, the big orange foam rollers are called “Pene” rollers. There is one up top and one in the lower half of the assembly and they are both the same. The DCP700 parts book didn’t spare these, but the more-recent families (J75/C75 and V80) both list it as part number 059K56451 (also found under: DC700DTFR or V80DTFR).
Let’s continue the procedure where we left off—removing the upper foam decurler roll:
TOOLS REQUIRED
- #1 Phillips-head screwdriver or 5.5mm hex driver
- Small flathead screwdriver

PROCEDURE-Part 2
1.Remove the upper decurler drive roll. At the rear end of the roll, remove one e-clip and the bearing. At the front end, it’s best to leave the black plastic retainer in place, as it can easily break if you try to remove it (photo #11). Pop off the front e-clip and bearing, and the upper decurler drive roll comes right out. Inspect the drive roll’s surfaces for any serious wear; if it has developed a wide groove where the pinch roll makes contact, it could potentially cause wrinkled copies.
2.With the drive roll off, the drive back-up roll and its narrow metal shaft will drop off easily. Inspect and clean the single white back-up roll and its bearings. (photo #12)
Remove the upper chute (four screws, photo #13)
3.Now you have access to remove the front rocker-arm support bracket. (one screw, photo #14)
4.Remove the upper decurler foam roll. Pop off the front and rear e-clips and slide the bearings off. Inspect the rocker arms, which support the foam roll, for damage. You can leave the rear rocker-arm and its bracket in place.
5.You already have the lower decurler drive roll off (refer to steps 4-8 in part 1 of this pair of articles). Now prepare to remove the lower foam roll by removing the lower chute (four screws, photo #15).
6.Inspect the 12 mylar feed-in guides on the lower chute for signs of damage or burrs (photo #16). Repair or replace them if necessary. Also, clean up and inspect the three drive roll back-up rolls—make sure the tiny bearings spin freely and remain seated firmly in the ends of the rolls. Note that these three rolls are identical to the one in the upper half.
7.Remove the lower foam roller. Start by popping off the rear e-clip and bearing (a rectangular hole in the top of the rear frame is helpful for reaching the e-clip with a tiny flat-head screwdriver). Next, go to the front end and remove the inner of the two rocker-arm support brackets (photo #17). Removing the rear bracket makes things more complicated, so leave it in place.
8.Inspect the rear cam follower. This black plastic piece sometimes breaks (photo #18), leading to a lack of pressure on the upper foam roller. If yours is broken, a metal replacement cam follower is available (655N50090). A tiny e-clip at the rear end must be removed to get the cam follower’s shaft off. Photos #19 & 20 show how the new cam follower and its spring should be positioned.
That should do the trick! Your decurlers should now keep your copies flat and beautiful. Happy repairs everyone!
