Jam 0523, 0524, 0533 & 0534

[tmaged]

Just curious if anyone has a solution to these jam codes on any of the Alphard II series machines. I have a 4551ci & a 4501i with quite a few of these codes.
Also a 6500i with the updated Alphard II paper feed units exhibiting the same. All have updated firmware.
The 6500i has had everything replaced regarding the desk unit. Both P/F units, drive unit, new vertical transport unit.
The 4501i has just over 20k on it.
Thanks for any insight.

I don't have any new information on that but will be interested in the responses. But you already know that. =^..^=

Have you investigated the paper empty actuator and sensor{s|. Had one on an older model 6330, a couple of weeks ago were it would run 10 to 15 pages and then indicate a jam, open the paper drawer, no jam and everything looked normal. Thinking the rollers were worn I started disassembling to replace the rollers and noticed the empty sensor actuator hanging up. The machine thought that that the paper was at the top so it never activated the lift motor to raise the paper table to provide more paper so eventually the feed rollers did not have enough pressure to feed the next sheet. Can't remember if we also had multiple sheet feed errors. On both models it is only the weight of the plastic actuator that lowers it, no springs or other weights, so any binding could cause the problem. We have not had this problem on the models you referred but it might be worth a look anyways.

It's worth a look. The odd thing to me is that I get the jams on both trays 3 & 4. On the one machine I've replaced everything to try & figure it out including the drive pack on back. I could see if there might be a problem with a sensor or something, but that should only affect one of the trays.

Hi Tony,
I agree that it should only affect one tray. Have you ever found paper behind the drawers? We had one customer that notoriously over filled the LCT and wound up with paper behind the drawers causing numerous headaches. I mention this because we found several times bits of paper in the connector in the back preventing the machine from recognizing the condition of the drawer. If they have opened and closed the drawer numerous times with a sheet of paper behind the drawer it may not be obvious that a shard of paper is blocking the connection. It is also weird that you have the same condition on several different machines. At the moment I cannot think of a common denominator that would cause identical jam codes on the different units.

I went to the 4501i today & installed the old style P/F units from an off-lease machine we have. I set up KFS to notify me of any jams, and I haven't got one today & was there first thing this morning. It had 7 0533 jams yesterday. This was a new machine just placed in July & it only has 23k on it. I'll keep this thread updated when I learn more. I'd be curious to see if others have the same jam codes on their Alphard II's.

Those jams were usually worn out pulleys, rusty clutches, or really bad paper quality. In your case i believe something is wrong with that PF in general.

Update to this thread. The 4501i that was having the 533 & 534 jams, hasn't had a single one in the 3 weeks since I put the Alphard I feed units in it. Unfortunately this one is 75 minutes away, so I can't really troubleshoot it as I'd like to.
The 6500i with the Alphard II feed unit's in it hasn't had a problem since I replaced both torque limiters.
I wondered when I ordered the new ones, why the torque limiters were 1/2 the price of the whole feed unit. I pulled one of the torque limiters apart to check it out. There is no spring & hub, but a magnet that does the resistance.
These are the same torque limiters that the Alphard I feed units use as I checked that out also. I'm guessing at some point Kyocera had separation issues with some of these, thus added the pressure adjustment on the Alphard II feed units.

Thanks for the update Tony.

My ASM just sent bulletin G198. It addresses the clutch stopper in the frame being to wide. The clutch spins & smacks the frame breaking the copper wires inside. It says it can cause either no feed or multiple feed jam codes.
The torque limiter fixed my issues.
As a side note, if you read the bulletin on the feed units with the spring adjustment, less spring pressure equals more separation strength. I noticed on the new boxes, they went back to a wrap spring torque limiter. I guess the magnetic ones weren't as good as they thought.
