AF3030 wrinkling or creasing

[Smee]

Im having an ongoing battle with a machine crinkling or wrinkling the paper. Its kinda like worm trails from the leading edge to the trailing edge.

The paper is getting creased before the fuser and its getting ironed out when it goes thru the fuser. I thought this was bad rollers in the fuser but we've put in 2 new fusers so this isnt the problem.

Whats really annoying is it only seems to happen very rarely - its never happend while i have been at the machine but i have seen the samples and the client says its happening ALL THE TIME!

Is it some sort of registration problem? Like its getting too much buckle or something? Or bad paper?

Thanks for the help!

are u very sure that the paper is creasing before the fuser? i have come a cross this problem a couple of times before on panasonic, minolta, and ricoh.
solution 1: check if the paper is not screw when leaving the tray (disable tray by tray to see if the problem goes away)
solutoin 2: relay roller pressure not the same on both ends or something in the paper path. clean the rollers and check to see if a spring is not missing from the relay rollers.
solution 3: the one that i found on ricoh, the pressure on the press roller in the fusser is not equal on both sides. or the latch on one side is broken.

I also found that this problem is extremely intermittent

Thanks Allan - yeah I'm sure its before the fuser as the creases are ironed out flat from the fuser rollers. I'm also sure its not the fuser as I have put in 2 different refurbed fusers with new hot rollers and pressure rollers in the last 2 months - so it's been creasing now with 3 diferrent fusers total.

Ive also put new feed rollers and friction pads in both trays, also changed the feed clutches due to a seperate jamming issue.

And ive checked the paper tray guides to be tight against the paper and educated the user about this to stop skew......but the fault keeps coming back!

Drum Guard ?

Does the machine have a drum guard, i have found that if the half moon gear jumped a step
it does not lift out of the way properly. >> Remove the drum Guard ?

Did you check the worn grove in the lower fuser bushing. Some get a grove worn rite in em.

I have had this issue when there is moisture in the paper. I know you say it happens before it hits the fuser, just a thought. Let us know what you find.

I believe you can try adjusting fuser with a spacer behind one or the other of the 2 fuser mounting screws.

clean the paper guide plate at fusing unit coz some tonerharden stick to the plate

I agree, clean the entrance guide in the fuser unit, I have had this fault on a few of these machines

3 different fusers seems unlikely it is fuser. Though that is often the case that it is. I lookup and see AF3030 is same as Savin 8030 so I ask you, have you replaced the FOAM ROLLER?
Also as mentioned by Allan I often see Reg Roller with something on it, adhesive, corrosion. Also failing Broken plastic holders or springs for the Reg Roller or Relay Roller also cause this. Also maybe plastic bur develop on the plastic paper gates near registration/transport sensor.

Yeah Im also pretty sure its nothing to do with the fuser. My last visit I educated the client on the paper dampness - its stored in their IT room which is cooled at 17 degrees C - and asked them to change the paper as soon as the fault occurs.

I also asked them when they load paper into the trays to move the bottom stuff to the top so the old paper dosnt sit in the bottom of the tray for too long....

I was driving past and called in today and it still creases so im going back on Monday to have another decent look and try out a few of your guys suggestions. In particular the reg roller springs and I noticed the mylar near the reg roller? has a nick in it so I will replace that also along with the foam roller.

So at this stage its definately not the fuser or the paper - ill update as soon as possible, and thanks heaps for the ideas!

Also, make sure the guides in the paper drawers are set correctly, skewed paper will wrinkle in the registration rollers.

It's a long shot, but have you checked that the exhaust fan is working and has sufficient air flow? Also, I came across one of these machines in the filed that had been refurbished and the mylar sheet, under the catch tray that directs the air to the exhaust fan, was missing. This was causing condensation in the optics cavity, but could also possilby cause creasing.

Just a thought, use it, don't use it....Cheers
