IR3300 tray lift mech

[BrickPilot]

Hi all.
So far in my job I've mostly stuck to fixing printers. The other day I agreed to "see what I could do" for a charitable organisation, in need of help. This was after learning that the local ASA takes weeks to front for non contract jobs and is seriously overpriced.

Anyway, I need help on my learning curve please..

Fault is, when the motor runs for paper feed, bin 2 base plate repeatly lifts, rather than just the once that would be required to pick paper. This causes a repeat banging noise which is also present when feeding from bin 1, which otherwise works normally. Noise is not present on power-up.

Presumably there is a clutch/solenoid arrangement failed to do it's job, but without a service manual I can only guess.

Any help to save time on this one is very appreciated.

lift problem ir3300

hi,i guess you check first your pick-up rollers,feed rollers and separation rollers assy..that could be the source of noise..maybe its time to replaced these parts...hope my suggestions helps

It's a broken lifting sector gear.
If you have a look at it you'll find a couple of broken teeth on the gear.
As the gear starts to lift the paper,it hits the missing teeth and the lifting plate drops....lift/drop/lift drop....that's the noise you can hear.
Seen it a million-gazillion times on 2200's and GP's.
It's also a royal pain in the backside to strip the paper feed assembly down to almost bare bones to replace it if you haven't done it before.
Having the parts manual helps a little....but not a lot.
Good luck buddy.
PS:
Are you in Sydney?
If so I can make a couple of calls and try to get you a paper feed from a wrecked 2200 from the Canon HQ at Nth Ryde?

Thanks for your reply. As Bin 1 was ok, I swapped pick and sep rollers prior while verifying this section "looked normal".

If it even remotly smells like a "love job", then all hope is lost for a quick fix. Isn't that the rule? Thanks for your reply.
You obviously know this fault. What ball park x$100 would you expect for such an assembly (upper guestimates?) PM if you like.

Thanks again

It may be the Sector Gear, but the symptoms you described can also be caused by the Pick-Up Locking Lever for tray 2 being wrongly positioned. When this happens, the tray 2 lifter is kept active at all times, resulting in a loud clunking noise as it repeatedly tries to lift.

Firstly, check for broken teeth on the Sector Gear. If it is damaged, then it's actually very easy to replace for tray 2. All you need to do is remove the lifting plate, and the Sector Gear is attached to the end of it. If you had to replace the same part for tray 1, well that would be a different matter...

Checking the Pick-Up Locking Lever is a bit trickier. Basically, you need to remove the PCB from the side of the Pick-Up Assembly, and the plastic cover behind it, then refer to the attached diagram which shows the right and wrong positions of the Locking Lever. Stand the Pick-Up Assembly on its end before removing the aforementioned cover, or you'll have gears and drive belts falling out. The Locking Lever should be resting against the half-moon arm of the Roller Holder.

This seems to match what I'm experiencing.
I can't prove it, but I suspect a paper jam was pulled from the path with less care than required. Could this action inflict damage as such?

Ok, above noted. I'll let you know what I find.
Thankyou

The Locking Lever is displaced when the Pick-Up Roller Holder for tray 2 is pushed upward while the tray 1 lifter is in the up position (which it would be if tray 1 was inserted). When this happens, the half-moon shaped arm of the Roller Holder moves above the Locking Lever. Most likely cause is the user removing tray 2 and nudging the Pick-Up Roller Holder when clearing a jam.

Damage to the Sector Gear is far more common for tray 1, because it's generally caused by wear & tear, not user error. It would be unusual if tray 2 had more usage than tray 1.

This is a frightening job the first time. The feed unit comes out easy enough, but there are probably 25 or 30 little mechanical levers, cams, & springs.

The first time I did it, I did sketches of the layout. Without the diagrams I could never have got it back together. The common wear items are:
(2) FB3-2856-000 Sector Gear Ratchet Lift
(2) FB4-2856-000 Lifter Claw
(2) FB4-5349-000 Lift Leaf Springs

Hi all
This is a bit belated, but this is just a thankyou to all above for solving this one. Your work is much appreciated.
