Question: Just found out customer has an AR-M205 not the 237. Do you know the procedure for that model?

Answer: # interrupt C interrupt.

Subject: Canon IR 3320 Jams in 3 Trays

Question: Top 3 trays are jamming. Near as I can tell, they are all doing the same thing. Paper moves about half inch out of the tray and stops. The way it’s built, you can’t really see what’s going on, but tray 2, you can watch a bit. Looks like the paper is getting to the feed rollers and stopping. The only difference I can find with the 4th tray is the feed roller is relatively bald and the rest are all new. I replaced all the rollers last call. This time I replaced 2 torque limiters but no change. Looks like the tread is the wrong way so I changed it on tray one, but no luck! Removed the feed assembly, inspected and blasted it, no change. The only thing I can figure is it’s got to be the rollers themselves. Maybe PR sent me the wrong ones or their compatibles are no good. They told me the pickup rollers and feed rollers are the same ones, but I’m beginning to wonder about that. Any help appreciated. Thanks in advance.

Answer: The pickup roller is different. The separator roller and the one above it are the same. Pickup roller: ff5-4552-020. Sep and feed roller: ff5-4634-020

Answer: Take the feed rollers out of tray 4 and put them in one of them that doesn’t feed. That should tell you if it’s the feed rollers.

Question: That thought occurred to me but I didn’t want to run the risk of making the only working tray not work either. You know how that goes. I’ll give your info a try, thanks.

Answer: Just seems strange all the trays stopped working at the same time, especially feed rollers all at once. Have you done a dcon clear? Or tried different paper? Or tried a different size paper or direction? Also you can pull out tray 1 and look in to see tray 2 feed rollers turning. Same with tray 3—take trays 1 and 2 out to see if the rollers are actually turning.

Question: Well, first of all, it is the pickup roller and the feed roller that are the same; the sep roller is the one that is different. Second, I got the first tray to work by swapping out first the feed roller and then the pickup roller from tray 4. It wouldn’t work with just changing one of the rollers, I had to change both. Then I got tray 2 to work by putting in the feed roller I had removed the tire from and flipped it around and again putting a different pickup roller on. Now of course trays 3 and 4 don’t work. I put a whole new set of rollers in it 2 or 3 months ago so they all still look new. I’m just going to order OEM rollers and see what happens, these PR compatibles just won’t work and I think it’s because the rubber is on backwards. I’m not going to spend half a day trying to flip them and tear up the rubber and not get a refund. Damndest thing I ever saw.

Answer: Funny, the OEM ones are made in China also; some Canon rollers are the same as some HP’s.

Question: Replaced with OEM, worked like a charm.

Subject: Konica Minolta bizhub 363 Optic Skew

Question: I’m surprised I didn’t notice this earlier; I have a Bizhub 363 that has a lead edge skew. 11 x 8 1/2 the sides (8 1/2 length) are perfect, showing the paper isn’t skewing. Both drawers and LCT are the same. The book has no adjustment for mirror frame height. Back on the analog machines, it was common to have to adjust mirror frame 2 to eliminate lead edge optical skew. Anyone have a fix? I came back to the office and a 283 is doing the same thing, though not as pronounced. The manual has nothing on this adjustment. Machine only has 60k on it. It came from the factory this way.

Answer: This happened a lot on other series. Take the left front of the scanner and yank up. Someone probably leaned on it or strapped it too tight. Don’t even try to play with the mirrors.

Answer: I’ve had the scanner frame get bent down on the corner but that gave me scans that had background down one side. Last time I had to adjust a scanner for skew was way back on a Di350. I fixed it by loosening the screw that secures the first mirror assembly to the scanner cable and sliding that end out of the scanner one way or the other. Loosen the front one because it’s better if the distances between the mirrors don’t change on the rear side. Good luck! I don’t think there is any actual factory adjustment procedure on the new models.

Question: You were right on! That makes total sense. The machine with 60K we just bought from a wholesaler and has been transported a few times for sure. The one in the office that had a small skew could have happened the same way. Thanks again! I’ll keep that info “filed away.” I’m bound to run into that some day!
