Hi,
I've been working on this one a few weeks, C364e with a finisher, and over 1 million copies on the meter. There was developer leaking in the back. All consumables have been recently replaced, (fuser, drums, developers, etc.). Lead edge is all over the place (same from all trays), random with 10mm of variation. When it gets too far off it will jam 99-01 (incorrect paper size). I replaced the paper feed drive unit (not the main drive), the whole registration section (including registration sensor and actuator), Clutch 4 (registration clutch), Motor M1 (transport motor), Clutch 1, 2, and 3. Flashed firmware to latest. Tried with Finisher disconnected also. Also temporarily replaced Front Side board. Konica Minolta's current Recommendation is replacing the Transport Motor (M1) and Clutch #4 as a set. If that doesn't work, replace the PRCB.
Any other suggestions?
Actions Taken by Tech:
Actions taken while on call:
1) Tech was able to get a registration unit from a known working printer in his office, the issue has with the J-9901 codes had decreased but they are still getting them.
2) Earlier notes indicate a grinding noise in the machine, Tech stated the machine is still running rough and he is unable to isolate where it is coming from.
3) Tech has also replace the wiring harness to the registration unit and the FSB with the same results
Actions Taken by tech:
1. Tried the reg-sensor, tested.
2. Paper feed drive assembly was replaced.

Actions taken while on call:
1. Checked the book on the registration rebuild parts.
Recommendations:
1. A5C1700101 Roller
2. A0ED700200 Roller
3. A161701100 Spring /A
4. A161701703 Actuator /T
5. A161702200 Bushing (X4)
6. A0ED700300 Gear 20T
7. A0ED700700 Gear 14T
8. A108M50100 Photointerrupter
Actions taken by Tech:
1. Image quality is gone.
2. Machine will jam 1 of 10 copies.
3. Machine still making noise even after replacing the Paper Feed drive assy.
4. Tech replaced the fusing unit temporary to see if the noise will stop.
5. The finisher got disconnected and he is still getting the same issue.
Lots of image issues. Replaced t-belt to roller 3 drums and 4 developers. Developers very dry. Developer leak in back of machine. Washed out image and color Registration off. LOTS of 99-01 paper size jams. Mostly tray 1. Lead edge random from all trays.
Upgraded firmware to G20-M1. Tested engine without finisher per Konica Minolta. No improvement. Installed K developer to fix black fill. Replaced CL3 feed tray 1 clutch. Replaced CL2 Vertical Transport clutch. Replaced CL1 feed clutch with 8Z part. Replaced the following in T1/T2 feed unit with 8Z parts.
All 6 tires.
All one-ways.
All torque limiters.
Vertical Transport roller and ball bearings between tray 1 and 2.
Tested with new M1 transport motor, no improvement. Took m1 motor back out.
Black developer had damaged gears. Teeth were sharp and probably skipping.

Machine sounds rough. WUM WUM WUM WUM sound after loop at registration. When feed slowed using thick 1 setting, you could hear skipping.
1. Jam 99-01 incorrect paper size controller jam from all trays and bypass.
2. MFP has 1,000,000 copies on it.
3. will flash up to current FW level and set SS#25 to hex 60, then reboot.
4. Print registration is shifted towards trail edge as paper is arriving early and probably not stopping at registration loop.
5. will detach the FS-534 and follow trap procedures.
6. If the problem persists,will pull the registration roller assy, inspect it, replace parts as needed.
