Tips on canon models

[blackcat4866]

Thank you mrfixit. It's actually got 530K, mostly out of tray #1. Tray #2 is legal and hardly used.

I did examine the pickup & lift sector gears. Isn't it just like Canon to save $0.10 by not using a lift motor or feed clutch? Do these sector gears hold up to heavy use? =^..^=

be careful of what type of oil u use there

I actually use transmission fluid, not oil, it's lubricity is as good as any oil, and it never gums up like oil can.

know what u mean/ i have had tech's use oil inside bushings that turns into a black hard gummy substance / talk about a troubleshooters nightmare

so one way bearings/gears slip more when dry than lubricated? i only have 6 years in the feild now and have always sanded and alcohol dried the shafts to prevent slip. am i doing this all wrong?

I would not sand a polished shaft that uses a one way bearing / it will effect the friction of the pins in bearing / if u look at the one bearing , u will see it is packed with lube at the factory/ cleaning shaft w/alcohol ok !! / also never sand a shaft that uses a composite type metal bushing/

metal shaft issues = friction>heat build up>+wrong lube= A Large Headache !!!!!!!

As Teckat alluded to, the one ways are pre lubed, but I always add a few drops of oil to them anyway. I have worked with one-ways, (we referred to them as torrington clutchs in the olden golden days at IBM), for a very long time, and they wear out sooner if not lubricated.

[blackcat4866]

Yes, as everyone has said, the shaft must be smooth and full diameter to function properly, and lubricated with a light oil. When they dry out the movable roller bearing do not grab right and it begins to slip, or lag in grabbing the shaft.

This is a common mistake with magnetic clutches too. Some techs try to sand the clutch surfaces to create more friction. Friction is not the way the clutch works. It uses electro-magnetism. And to get the most magnetism you need the maximum contacting surface area. So don't sand the clutch plates. It just reduces the surface area, making it slip more than before. And no oil either.

thanks guys

hi there
u can use WD40 for this kind of bearing it cleans and lub in same time without any future gummy things inside.

You can, and I've done it in the past ,however I recommend not to.
Bearings, torque limiters, are at spec, if you spin a bearing with your finger, it moves smoothly. Add WD40 a it spins loosely and fast, that can cause some slipping.

But I know that, we must do, what we must do,to get us thru the day.

I never use WD40 in a Canon Copier machine on anything that moves. It starts to stink when near heat or friction / it drips all over the place/ and u should never use it on a one way bearing/ I hate it when techs spray it on those Finisher spring clutches/ & one ways/ or plastic bushings. As a senior field troubleshooter -when I see that mess I have the tech come back and clean up their mess before I will troubleshoot an issue/ Had techs call me for oil spots on copies/ they couldn't figure out that it was from the WD40 they used in pick up assembly .

Dear teckcat:
of course using wd40 to spoil the place is forbidden, usually i drop on screw driver tip some of it and use it in clean and decent manner.also i prohibit my tech. to use it in gears and clutches, usually clutches needs cleaning not greasing.For pick up assembly it is very bad solution replacing pickup kit is the preferred to me.

it's a slippery slope \\\\\\\\

WD40,
Great for Bicycles
Bad For copiers.

ANY lube involved with Heat/Static must be a Teflon-silicone base gel or grease

ANY Spray lube will have a dispersant that WILL DRY UP.

EVEN the use of the (turbine oil) [the ones you find at graingers,hardware stores] in the semi clear container with the small tube/cap is going to sieze

The expensive teflon lube that "looks" like oil is GREAT.

The spray Silicone is death.

Get the semi clear High temp grease [That looks like silicone sealer for the bath room]
that stuff works very well.
