ricoh aficio 1075 feed problem

[Guest]

I am having a problem on with the paper feed on this copier , I can sometimes make five copies or 1 copy then it makes this loud noise and goes into jam paper the feeds up to gate b. its only with the tandem tray other trays work fine. already replaced all feed, pickup, sep rollers. checked motor ok thank you

what kind of loud noise? Humming, crunching, or grinding. I've had several of the PFU motors get weak and cause intermittent jams, although it's much more common for a registration motor to do this. Check your jam codes - is it a Jam 03 or a 15?

Developer has probably contaminated the paper feed units. First fix the developer leak, then replace one way bearings in the feed units (the main and probably at least tray 1 feed unit) and thoroughly clean all bushings and shafts.

FIRST check for evidence of dev leaking onto the gears, paper trays and machine frame, from the Brown bushes at the front or rear of the Dev unit. This will murder the paper feed gears and / or the motors! Replace the bushings as a complete set, front and rear, if required.

Swap Feed Stations 1 and 3. Does the fault stay at 1? If yes, may not be the feed station. Remove the Reg unit and check the black mylar vertical transport guides, replace if worn. Also change the 1 way bearings on the Reg unit.

I had one (Last Week!) with a faulty paper feed control PCB causing jams, only from the tandem tray. However, the jam ws only 2" out of the tray, not at "B".

If the fault moves to Tray 3, Change the gears, I would also change the feed motor as these are not expensive and can get very tight.

Im with TCS04 on this one. One other thing, whip out the duplex unit and if there's a mound of dev at the back right hand area you hav a lovely dev spill and you'll have to clean ALL gears in the pf section , good luck

Torque limiter

Didn't notice if you said so before but you should also look at the torque limiter as I have had those go bad and lock and actually throw the belt off the drive on high volume machines.

Would normally give the "2mm foldback" by the sep roller before complete failure, but worth changing all the same. swapping the 1st and 3rd staions would also confirm this.

Dang! forgot about the 1way bearings in the gears - these used to be a PM item for me, I changed them with every second set of feed rollers until Ricoh finally updated them, and still have the occasional problem. Developer dribble will be fairly obvious - the teeth will be almost completely eaten off the gears, but the torque limiter would likely cause folds if it locked or multifeeds if it stripped.
I stand corrected. The "Loud Noise" is still a bit odd, but tsc04 is right - the best way to tell is to swap the #1 and #3 PFU

thanks a bunch I will check these again. thanks

I have also ran into the leaking development unit problem. I rebuilt the feed unit, but it never did work good again. I had to replace the feed unit to keep it from misfeeding.

I've never seen these DVD Units leak unless the bearing that holds the shafts and the gears gets worn. We have to replace those rarely. Gears seem to be a common replacement item though.

try to check this B065 6323 Paper Feed Motor if its hard drive usally this one makes the noise due to hard drive.... as mention the past reply if the machine gets dev leakage replace the drive gears AB01 1490 Gear - 38Z, AB01 1491 Gear - 21Z... good luck

I'm just about to order 3 MORE sets of these (seems to be my fault for this year!) I would STRONGLY suggest that you order the dev bushings, both front and rear or you may well be back in a few weeks replacing the same parts again. They only take a short time to fit. Also, pull the reg unit and ALL the feed stations, then vac out the area.

I've started making shields from acetate to stick above the feed station area in the hope it will prevent the muck from affecting the feed. Sticks on the base plate of the machine and sits above the vertical transport door just to the rear of the paper path.
You may also find dev all over the feed motor(s) so I would replace these as required (not expensive), especially if the dev shows any sign of leaking at the front of the unit.
