Complaining about paper jam after lubrication

Hi!

So I have a Canon Pixma TS 8350, I have had it for about five years. It was making some annoying noise. Nothing new really, but I finally decided to try and quite it down. I opened the right side panel and sprayed the sucker with a synthetic lubricant a few times. But instead of stopping the noise, it started making new kind of noises and it sounded louder and faster. Actually I think it did help dampen the original noise to some degree. Soon after this, as I was using the roller cleaning function to trigger the noise, it started to complain about a paper jam and gave me support code 1300 (I think it was). Even without any paper in the cassettte. The cassette was taken out, and there was nothing in the rear paper feeder. How is this possible? How does it determine it's a paper jam without any actual paper in the printer?

I turned it off, unplugged it, turned it back on and I tried to print something from Word but Word said I have a paper jam, and the same code came up on the printer again. After a few rounds of this error and power cycling, it now gives me code 6A80 every time it powers on and prints out a blank. This latest code just tells me to cancel the print job and turn it off and on again, and if the issue remains to contact a service center.

So basically, I broke it by lubricating it. How do you repair something that's technically not broken? If I try to disassemble it, what would I do in there? Clean up the lubricant and put it back together? I don't know much about printers, and I have never taken one apart. But I can probably do this. Any tips on what to think about when doing this? Like, how do I avoid gettting ink stains? How do I remember what goes where so I can put it back together again?

Thannks for any advice.

I sprayed it in three or four locations behind this black plastic where the big gears and levers are located.

Basically, wherever there were signs of white or yellow grease, I sprayed it a little in hope of getting some needed lubricant in there to put out the noise, without having to take the whole thing apart to inspect it and apply some grease in all the right places and with precision. I did use a long nozzle to try to get it in the right spot.

The lubricant I used is a synthetic, adhesive/sticky lubricant that doesn't run. It contains PTFE and it turns thick as it dries. So it's like grease in a spray can. I was mindful of what I use, and this should be safe for plastics and seals.

I'm thinking I may have inadvertently sprayed a sensor. What do you think?
