I'm not familiar with the exact system you have but the simplest cause to this problem woulf be a sticky switch, since power is reaching the system for the stand by light to come on.

It is possible to test switches like this by opening up the stereo and touching an unbent paperclip across the two metal contacts that go into the switch. If it comes on then you know your switch is bad, however be warned that running electrical equipment with the casing off puts you at risk of receiving a shock if you touch the wrong part so I don't officially recommend this.

If the switch is faulty then you can either try cleaning it by spraying a contact cleaner such as IPA into it or just replace the part (though this will require soldering).

Otherwise, some stereo systems have an internal fuse that will blow to protect the circuit if you overload it so have a look for fuses on the circuit board.

How do I change the Waste Ink collector on a Pixma MP170?


Cleaning or changing the pad is a messy project. This ink pad reset will reset the printer ink use conter to new status and your pad full message will be gone. This is a common occurance with Canon printers and the fix causes no harm. I reset my own MP470 about two years ago without incident.

This reset has been sucessful on many MP150 and simular units and should work on your MP170.
The second works on models with different control pads simular to theMP470.

printer powered off but connected on power source , you must:
1. Press & hold stop/reset button, and then press & hold [ON/OFF] button.
2. When Green power lit, leave stop/reset button & press twice stop/reset (see orange indicator).
3. Leave On/Off button. Printer in actually service mode.
4. Press stop/reset 4 times (see orange indicator) if not blink restart above process from top.
5. After press stop/reset 4 times successful press On/Off button 3 times. printer will off.
6. Press On/Off button.

Error code 5100 check printer


This is probably a Canon printer and code. If so, it is the "ink waste pad is full" warning. There are work arounds to keep from having to clean the pad. Here are two methods to eliminate the message. The only other ways are to take it to a repair shop or dismantle the printer and clean the pad yourself. Not advised, This is messy.

This works on many different printers.
