If you remove the 2 screws from the rail (1 on each side) that prevent the tray from rolling out all the way you can easily get to the rear screw for the feed unit.

Thanks that would make things easier. Did not even occur to me.

Just an FYI, KM has a new ribbed pickup roller for these models. It is for the trays and the bypass tray. The new 654's are coming with it installed. The part# is A5C1562200. There is a tech bulletin for it.

I don't know if they're officially compatible(yet), but they should work. I've used the newer orange rollers and the black ow bushing(clutch) in the older 250s/500s that have the blue style with white owb (clutch), and it's worked fine even though it's not "official"

I would say yes! The pick-up roller have been the same with feed roller for donkeys years. The usual wear out in my case( obviously depending from customer to customer and paper type and manufacturer and usage) they would last in the range of 100-180k. Just for the sake of minimising call backs, i've changed all 3 (pickup, feed, sep and clutches) as a set. Now with this pickup i do just feed and sep as a set and all magic! Id imagine the pickup would last 2.5 a 3 sets of feed/ separation.

552 tray 3, 1301 jams. Copier with 1.6 million copies.

I know this is a 3 year old thread, but I saw something today that may help others. I was working on a Konica Minolta 552 (1.6 million copies), getting occasional 1301 jams, where the paper hardly moved out of the drawer. I removed the stop screws on the Tray 3 slides, and pulled it out to the end of the slides. Removed all paper, and rotated the lift shaft. Noticed that T3 lift plate was not lifting squarely. The right rear black lift cable was slightly longer, looks like the ball welded on the end of the cable was pulled off slightly. I bent a c clip above the ball, under the plate, and it leveled out the lift plate considerably. I noticed that the stacked paper magnifies a crooked lift plate, and after paper has been run several times, it gets fluffy/wavy, then it will jam regardless. To test this fill the Tray completely and run it all with a paper passage test. This machine would jam when the paper got to a certain amount remaining, probably maximizing the misalignment of the plate. Also cleaned lift sensor and paper feed sensors. This also explains why the front black guide plate (rests on paper next to feed roller) had excessive wear/grooves in it. Hope this helps someone!

KM also has a update for this issue, the TAD # is TAUS0902737EN03.

Subject:
Jam code 13-01 (1301), 17-09 (1709) or 17-30 when feeding paper from Tray 3 (1500-sheet). Jamming may be intermittent (more frequent if feeding thin paper).

Description:
Jam code 13-01 (1301), 17-09 (1709) or 17-30 when feeding paper from Tray 3.
Solution:
PROBABLE CAUSES:
1. The conveyance roller located in the Tray 3 feed unit has worn down due to low quality paper which changes the diameter of the conveyance rollers. This causes the paper, when fed, to contact the white plastic pressure rollers below the conveyance rollers. This happens after approximately one million feeds from Tray 3.
Replace the conveyance roller (p/n A00J 6011 11).

2. Paper is stopping at the paper feed roller because the Timing Belt/96L (p/n A00J 6198 00) has run off the Pulley/14T (p/n A00J 6196 00) onto the Washer (p/n A00J 6029 00).
Replace the original pulley with the modified Pulley/14T (p/n A00J 6196 11) and the original washer with the modified Washer (p/n A0P0 6640 00).
Note: Please refer to the attached Technical Notice and Parts Modification Notices for more detail.

3. The 3rd and subsequent sheets of paper jam in the Tray 3 Horizontal Transport section. The activation timing of Tray 3 paper feed sensor (PS21) is later than the designed basis time because thin paper may sag at the detection point of the actuator for PS21. The stop timing of the paper is delayed, and the distance between the paper and the previously fed sheet becomes narrower. Consequently, Horizontal Transport sensor (PS29) cannot detect the lead edge of the paper and a jam occurs.
Install modified parts:

Adding two ribs on Paper feed base frame/1 (p/n A00J 6001 04).
Shape change to Actuator (p/n A00J 6040 02).

Please replace the Paper feed base frame/1 and Actuator with the modified parts at the same time.
The Paper feed units are also modified (p/n A00J R757 11 for bizhub C451/C550/C650 and p/n A0P0 R722 11 for bizhub C452/C552/C652). Please refer to the attached technical and parts notices for more detail.
Notes:
a. The modified parts have been installed in production of the bizhub C552DS/C652DS.
b. If the actuator is still not resolving the issue, install plastic material 2-3mm thick to the edge of the actuator to PS21. This will cause the paper to strike the actuator sooner.

Please see attached photos.
c. This has been escalated to KMBT.

4. The main body firmware was upgraded, but the FS-526 finisher firmware was not upgraded at the same time.
