[Jamming] C452 Duplex Printing Problems

[Won24]

Every time I try and print double sided with the C452 the paper prints fine on one side, goes into the upper tray then throws a paper jam error in what I assume is the duplexer. It stops about an inch or two so after the flag just as it passes through the rollers on the upper door. No creases or folds, just errors out the printer.

I am a novice at paper printer repairs, but I am skilled at technical assemblies and competent with electronics. My best guess is that either the flag is not registering, or there is an encoder that isn't properly indexing as the paper passes through. Is there a diagnostic mode where I can see the individual sensors to find what's erroring out, or is this more of a pre OBD2 kinda thing where you have to be smarter than the machine to fix it?

A side problem the printer has had since I bought it at a few years back at government auction for $105 is the lower paper trays jam constantly. I assume the transfer rollers are bad, but I've always just used the bypass or upper trays to print and it wasn't a real problem for me. I guess while I fix this I'll buy a new set of transfer rollers for those trays.

Thanks for any pointers!

What is jam code? there are bushings on the registration rollers that will sometimes gum up causing some strange issues .

Error code is 32-01, area 13 I believe is what's causing trouble.

Error code is 32-01, area 13 I believe is what's causing trouble.

Jam code 3001 (30-01), 3201 (32-01) or 7216 (72-16).

Error
Jam code 3001

Root Cause
Jam code 3001 (30-01) is indicated, yet 3201 (32-01) or 7216 (72-16) may also be displayed.

• Paper may be stopped in the 2nd image transfer section. The jamming occurs from all trays and is most frequent when using letter paper in the portrait direction.
• Jamming at the exit with the first sheet of paper half-way out of the fuser and remaining paper jamming internally.
• Abnormal noise is heard that sounds like paper crinkling.
• Copies folding in the fuser unit.
• Jamming when duplexing.

Workaround/Fix
PROBABLE CAUSES:
1. Broken/missing latch (front or rear) on the right side door.
Open the right side door and check the latches which keep the door closed. There are three (3) unique parts; the Lock Levers (Lock Lever/Front - p/n A00J 7065 00 and Lock Lever/Rear - p/n A00J 7066 00) and the Lock Claw/Holder (p/n A00J 7077 00 for bizhub C451/C550/C650 or p/n A0P0 7077 01 for bizhub C452/C552/C652/C552DS/C652DS). Replace any broken or missing latch.
Note: There are two (2) Lock Claws/Holders, one in the front and one at the rear. See attached Parts Manual pages and photo as references.

2. Damaged gears in the Eject Drive Unit (Paper Exit Belt Drive assembly).
Replace the Eject Drive Unit (p/n A00J R726 11 for bizhub C451/C550/C650 or p/n A0P0 R736 11 for bizhub C452/C552/C652/C552DS/C652DS).
Note: Please refer to attached documentation if an abnormal noise is also present.

Paper may be stopped in the 2nd image transfer section. The jamming occurs from all trays and is most frequent when using letter paper in the portrait direction.
PROBABLE CAUSES:
1. A damaged Guide Assembly is either catching the paper or is bent and not pushing the 2nd transfer roller holder into place.
Re-form or replace the Guide Assembly (p/n A00J R724 00 for bizhub C451/C550/C650 or p/n A0P0 R750 00 for bizhub C452/C552/C652/C552DS/C652DS). The Guide Assembly is located in the paper path directly underneath the Transfer Unit.
Two issues can occur which will cause paper misfeeds.

• The Mylar can become deformed and catch the paper.
• Metal part of the guide can get bent which will cause the 2nd transfer roller holder not to fully seat when the right side door is closed.

Either one of these issues will cause paper misfeeds in the 2nd image transfer section of the machine.

2. Failed one-way gear (Gear 16T).
Replace the one-way gear located at the exit unit (p/n A00J 8951 00).

3. A stalled exit roller drive motor (M4).
Replace the exit roller drive motor (p/n A00J M120 00 for bizhub C451/C550/C650 or p/n A0P0 M124 00 for bizhub C452/C552/C652/C552DS/C652DS).

4. Incorrect fuser drive speed.
Increase or decrease the fuser drive speed within the Service Mode ? Machine Adjustments.
5. Transfer belt not turning.
Check to make sure that the M1 drive motor (p/n A00J M113 00 - Brushless motor/12) is operational, drive gears (Gear 44/70T - p/n A00J 2200 01 and Gear 88T - p/n 4004 2540 01 for bizhub C451/C550/C650 or p/n A0P0 2208 00 for bizhub C452/C552/C652/C552DS/C652DS) are not broken or stripped and are meshed/engaged properly.

6. The secondary transfer roller is faulty. The roller is either worn so the circumference is less than when new, or it is beginning to bind.
Replace the secondary transfer roller (p/n A0P0 R719 00 for the bizhub C452/C552/C652/C552DS/C652DS or p/n A00J R715 00 for the bizhub C451/C550/C650).

Jamming at the exit with the first sheet of paper half-way out of the fuser and remaining paper jamming internally.
CAUSE: Broken exit roller drive gear(s).

SOLUTION: Replace gear 16T (p/n A00J 8951 00) and/or gear 16T/26T (p/n A00J 8911 00).

Abnormal noise is heard that sounds like paper crinkling.
PROBABLE CAUSES:
1. A separator claw on the Transfer Unit may be broken by a sheet of paper when 2nd image is being transferred. (bizhub C451/C550/C650 only)
The Mounting Plate/Upper and the Holder in the Transfer Unit has been changed to prevent this. Replace the Transfer Unit with a modified one (p/n A00J R714 44).

Notes:
a. The previous part number for the Transfer Unit was A00J R714 33.
b. This issue affects Transfer Unit Lot Number A00JA500L0182313 and onward.

2. The shaft hole and the tooth surface of the Gear (p/n A00J760301) in the Fusing Unit may wear excessively, and there is a possibility that abnormal noise or drive failure may occur.
Replace the Gear and the Support Shaft (p/n A00J760401) at same time.


Note: Please refer to attached Parts Bulletins #8695 and #8747 for detailed information.

Paper folding in the fuser unit. (bizhub C451/C550/C650 only)
CAUSE: Worn or damaged transfer roller.

SOLUTION: Replace transfer roller (p/n A00J R715 00).

Jamming when duplexing (jam code 7216 or 72-16).
CAUSE: Failed switchback gate control.

Jam code 30-03 (3201) when a copy or print is attempted.

Workaround/Fix
CAUSE: Improperly mounted actuator or failing exit sensor (PS39).

SOLUTION: Verify that the Paper Exit actuator (p/n A00J 8923 00) is properly mounted and moving freely. Check the Exit sensor for proper operation by entering the Service Mode then State Confirmation. The exit sensor can be found on the Sensor Monitor first page. Replace the Exit sensor (p/n 9335 1300 61) if it is not changing state.

Workaround/Fix

I'm thinking it's something like this. There's no paper crinkling or strange noises, it seems to just flag a jam because a sensor isn't registering. How do I perform a sensor check? If it's a roller/gear train driven rotary encoder, how do I know how many pulses it should register per rotation?

Thank you! I really appreciate the support. I need to print out some technical manuals for an ECU I am going to start building a wiring harness for in a month or so and I really hate reading this stuff off a computer and not being able to take notes and highlight . I'm really missing my folder and saddle stapler. It's such a silly thing to own, but it makes such a big difference lol.
