Ricoh Aficio 1232c - Paper Jam B and Z (Only when Duplexing)

[nan]

Ricoh aficio 1232c. The registration clutch SP 5804-11 is NOT making a clicking sound in output mode. Paper jams at point B and Z when duplexing ONLY. What part number do I need to replace this reg clutch and would cleaning this reg clutch out help?

Is there anything else I can check. The T/B Cleaning clutch is fine and making the clicking sound SP 5804-33.

All help very much appreciated.

duplex jams

I would rather look at the gate solinoid in the duplex rather hen the registration clutch especially when this is working fine in single mode. Check also the jogger it self as sometimes the end pins get broken.

What jam codes are you getting?

duplex jam

u can check the motor in duplex unit

What jam codes are you getting?

I am getting original jam code: 006,005,055,055,

Copy jam history: 023,004,005

Printer copies and prints fine in SINGLE MODE! ONLY in DUPLEX MODE does it jam at B (paper coming from the duplexer to the fuser) and Z(within Duplex Unit)

u can check the motor in duplex unit

Checked all the motor in the duplex unit! working fine!

The paper only gets stuck halfway when a half of the paper exits the duplex unit going towards the fuser to print the 2nd side!

Printer/photocopier works fine in single mode?

believe it or not check/replace the reg. clutch sounds crazy but the single side should vary a couple of mills but will cause jams on duplexed copies.

Replaced the parts :AX20-0240(reg clutch), 2 x AX20-0239(relay clutch), 2 x AX20 0224(feed clutch). Still no joy! Getting jam at point B and Z ONLY when DUPLEXING?

Single mode works fine?

POINT B is when then paper is exiting the duplexer to copy the 2nd side going into the fuser unit! It did duplex once, then 2nd copy get jam at point B as above?

I have cleaned the registration sensors as well?

Any ideas what else I need to check?

Have you tried checking the interchange unit? Check for warping and proper movement of the actuators. Check the guides for warpage, burrs, etc. Have you tried it from all trays and different sizes and orientations?

[TonerMunkeh]

I'd be guessing interchange unit too. Check the solenoid actuator arms for warping, make sure they're being moved by the solenoids correctly. Also check the junction gate on the top of the duplex unit itself, I can't remember off the top of my head if it has that little pin on the back that actuates it like the Russian does, but if that's snapped it causes quite similar jams to the ones you are describing.

How do I check the solenoid actuator arms for warping and the solenoid is moving correctly. How do I check the junction gate on top of the duplex unit and check the little pin on the back of the duplex unit is NOT BROKEN. Any manuals on the duplex unit? Do I need to dismantle the duplex unit?

I would rather look at the gate solinoid in the duplex rather hen the registration clutch especially when this is working fine in single mode. Check also the jogger it self as sometimes the end pins get broken.

How would I look at the gate solinoid, do i need to dismantle the duplex unit. The jogger where would i look for the end pin to see if it is broken?

Open the duplex unit to the right, then you open the black paper guide to the left. On top of that paper guide is a gate with a pin in the back that may be broken. To check the solonoid you have to take the duplex unit apart. It does sound like your problem is somewhere in the duplex unit, and not in the machine.

I would also suggest that you check your invertor section as well as the junction gate to see if that little pin the the solenoid pushes to open if it is not broken other thing that can cause plenty grieve on these machines are the gear boxes that has been modified.Registration clutch usaually lasts for about 500K prints.

Goodluck and check your mod bulletins possible answers to your question on Ricoh web sites.

Checked solenoid actuator arms is working fine. Checked pin in the black gate in the duplexer, it is not broken. The gate solinoid is fully functional within the duplex unit. Inverter and transport motor is working fine as well in the duplex unit.

When a single paper exits the duplex unit, the Exit sensor in the duplex is activated and is working fine! However when this transport roller( in the duplex unit at the bottom) sends this single paper to the main unit registration roller it JAMS then a (Point B)??

FYI Single sided A4 copies work fine from all the TRAYS.

Any ideas?
