Gday sir, Having been working normally, my Canon Pixma

Resolved Question:

G'day sir,

Having been working normally, my Canon Pixma iP4500 has decided not to 'power up' today. Mains power fuse changed; a different cable used; confirmed that mains outlet socket is properly 'live'. In spite of these power supply checks, the printer will not power up when normal on/off switch activated. Any ideas, please? Internal relay?

Many thanks - XXXXX XXXXX

G'day Richard,


 


None at all - no power anywhere.


 


Sorry, but there will be a delay (20 min-ish) before I can get back to you again.

Thanks ok Tony

There are 3 circuit boards in the printer; the control board (HID) - the equivalent of a motherboard (MPCC) and the one resting on the internal PSU. I suspect the PSU has blown.


Are you ok to remove the PSU and check the internal wiring for voltage. If they are all dead = usually a blown fuse and/or over-aged/blown PSU capacitor will be the problem.

Let me know the results please

Many thanks for valuable pointers - I have successfully messed around with the innards of computer cases but am not really tech-savvy enough to do what you suggest, having avoided the insides of printers. In any case, I would then need to source a replacement PSU / capacitor, if that is feasible.


 


I have a note of the 'case' number and will get back to you with the outcome when I have enquired further about supply of parts.


 


Most grateful for your very prompt help,

Your welcome Tony.

you would need to really take it into a canon repair center to have that done, as it has very hard to get the parts for consumers.

I have though marked this question to never close, so any issues just let me know

If you would like any additional information or assistance, please do not hesitate to let me know.

And if you can take a second to rate my service, that would be greatly appreciated.

Thank you
