Canon Maxify MB5450 error 7100 victim – paper jam

Hello everyone,
I would like to share my issue with my Canon Maxify MB5450 printer, which is displaying error 7100 – paper jam… but with no paper inside.
I’ve had this printer for a few years and I hardly use it, as my ink tends to dry in the print head.
So after running the print head cleaning cycles suggested by the printer, I wasn’t getting satisfactory results on some colors.
I decided to perform a "deep clean" of the print heads using cleaning products (like a syringe and rubber tubing that we attach to the cartridge slots).
After this cleaning, I ended up with an error message from the printer "7100" which corresponds to a paper jam. Of course, there is no paper stuck inside, especially since it worked just before the cleaning. And since then, I haven’t found any procedure to try and fix the problem.
After contacting Canon, they offered me a repair fee of €151 (ouch!) or a 20% discount voucher towards a new printer.
On the principle, I find it unfortunate that Canon prioritizes pure business rather than helping its customers try to keep their products alive, especially since I believe this is all due to a paper jam sensor that must have gotten clogged during my cleaning.
And after disassembling a good part of the printer, I can’t figure out where this sensor is to clean or even replace it (again, I haven’t found any websites allowing me to purchase it (and I was secretly hoping for an assembly manual to identify it in the printer)).
I don’t know if anyone has already resolved this issue, but if so, I’m all ears just in case ????
Thank you and have a nice day
Laurent

PROBLEM SOLVED!
First of all, thank you jeannets for your response that helped me refocus on the subject! I refocused on the cables you mentioned, but it turns out that there are a number of tubes related to vacuum systems. So, there’s no impact of having ink on them (it’s just dirty).
So, in a cleaning effort and since I was at it, I took the opportunity to clean the clear plastic blade guiding the print head. This strip, which according to all recommendations should never be touched, seems gray because it actually has tiny vertical lines that help the print head position itself during its movements.
In short, I applied a bit of cleaner on this blade. (I tore off a small piece of paper towel on which I put some cleaner, then I tried with a dry piece of paper towel afterwards) and, oh miracle, the issue disappeared upon restarting!!
This would mean that when the markers on the blade are dirty, the print head does its back and forth for adjustment/calibration, and if there is any doubt, it ends up in an error code (which is understandable) but the printer seems to return the "paper jam" error code which is not the right message for the average user.
I am a bit surprised that this could be the only issue and that Canon has no information on the subject.
Well, let’s see if this can help other people in any case

Hello,
I can't find the exploded diagram of this printer either... But your reasoning about this sensor seems good to me...
-- Logically, it is located on the paper path... By following the wires, you should reach something electrical...
-- These sensors can be a micro-switch, activated by a lever... Or a "fork" with an optical cell, with a lever cutting the infrared beam... And an ink projection can put it in the dark..!! and the ink will dry, and that can last for a while..
-- In your handling, you may have also broken/cut a wire, or messed up a sensor, misaligned a lever...
-- Sometimes... turning the printer upside down, tapping it a bit, then putting it back the right way can reset some movements...? It doesn't hurt to try, but it does require a bit of space..
Here are a few hints that can work wonders... Or not..?
Good luck and patience.
Indeed, this graduated band is used for the incremented or decremented counting of the print head position... It is initialized when the printer starts up.
This dirty or crumpled ribbon causes positioning errors and thus affects the printing...
Let's say that the error code (paper jam) can be quite surprising..!!!
You were more insightful ... Well done.
Best of luck.
