The squeaking only occurs during the cleaning cycle and the operation of the printer is not affected. Is there somewhere I can lubricate to stop the squeak?

Canon were, BUT 3D are better.

Just ignore it, that’s what I do… ;)

I'm an engineer. A squeak when there should be no squeak means that something is wrong, be it trivial.

I'll try cleaning all the bits that move.

Too true, but all the moving bits inside these printers are plastic, so engineering cleaning may do more harm than good, and given time the squeak will stop anyway.. :oops:

Point taken! I HATE squeaks. I'm a regular cyclist and I spend hours tracking down recalcitrant squeaks, mutters and groans on my bike (it's probably me that groans). You are quite right - plastic is funny old stuff but I do have a solution (ha!) for it in me toolbox. I'll let you know how I get on. On the other hand, it might, as you say, go away when it rains (I live in Spain). That happens to my bike, too!

Bikes can squeak when you get road oil on your brakes pads and it does indeed go away when it gets washed off from the rain..
Happy and safe cycling… :thumbsup

There are lubricants that are safe for plastics and that are suitable for printers. Canon uses a grease Floil KG107A and if you cannot find that Molykote EM-30L is a good substitute, also safe for plastics. This thread has links to the lubricants and tells how a squeaky Canon Pro 9500 finally was cured.

There are no service manuals available for the MG5350, but as it is somewhat similar to the MG5250 maybe a service manual for that printer could also be useful for disassembly of the MG5350. This thread has an instruction for taking apart the MG5350 and links to sets of photos showing the disassembly of the MG5350.

If the lubrication is a success then please post your results, if possible with photos.

Thanks for this, PeterBJ. I can obtain the Molycote EM30L from Amazon, and I have downloaded the MG5250 service manual from your link. You're a mine of information, sir! The grease is £20 but I can use it for other things - the one on Amazon is in fact advertised for sewing machines. The manual will be a real boon - thanks for that. I need to buy a spudger; I usually manage to get the plastic panels off but am always in fear of a crack or a broken tag!

I've also found a You Tube video that tells me how to reset the counter should I need to. Now, all I need is replacement ink pads!

Printer Knowledge, your knowledge and my engineering expertise (!) should keep my MG5350 on the road for a bit longer.

Oh, and I fixed the squeak on me bike…

A bit more…

I use a dry spray for my bike chain from Lidl and made by Baufix. On their website, although I cannot find the components, under their technical details it does say that it is suitable for metal and PVC. PVC is a particularly soft plastic, so I'm thinking it's probably OK to use on the other plastics in the printer - probably nylon for the cogs and rollers and ABS or similar for the casing.

Any thoughts on this? T'would save me paying £20 for grease, and it's easier to apply.

Silicone oil and silicone grease should never be used in electronic products. It can migrate and ruin contact surfaces and cause all kind of problems. So make sure the bike chain spray is free from silicone and solvents that could damage plastics.

The procedure for resetting the absorber counter from service mode is the same as for the MG5250 and other printers of the PGI-x25/CLI-x26 cartridge generation, so see this thread.

I think new absorbers are nowhere to be found, but the old absorbers can be washed with lots of warm, not hot water. A good quality rubber or PVC gloves is recommended.

YouTube videos might be right or wrong. Some are uploaded by helpful people who know their stuff, some are uploaded by some not so knowledgeable people with wrong ideas, and even worse, some videos are deliberately wrong intended to cause damage. I suggest to ask on the forum before following advice from a YouTube video. Here is a thread about a video that tricked me into believing that a new procedure for resetting some Canon printers was to be introduced. And here is one more thread about that video.
