Canon MP287 Alarm Lights Steady But No Power

I have 2 units of Canon MP287  3 in 1 printer. The old one continually flashing error E05 as both ink cartridges are not recognize because of a damage on the flat cable ribbon connecting the ink cart and logic board.

The new one I bought few months ago reached its printing limit meaning "Ink Absorber is Full" flashing an error code P08. So I need to reset the printer.

Unfortunately, I can't reset the printer though I properly followed the correct procedure of resetting the unit. Then after so many attempt, another error appears which is P07 which refers to ink cartridges not properly place. But no matter how hard I tried to re-seat the cartridges the problem still there. And when I tried to reset the unit again the alarm light steadily appear and there's no light on POWER button.

I suspect that there is a serious problem inside the printer and search for additional information regarding the error. I've been dealing with this matter over a week now but afraid of removing the logic board since I'm not sure about it. I was able to find a concrete idea behind this error through some forums and a video uploaded on YouTube. Some said the problem lies with what they called "logic board". 

So I thought of replacing the logic board with the one from the old unit of the same model thinking of this as the main problem. After a few hours, I did replace the logic board and did able to bring it back to a normal operation by resetting the unit first. Well, there's no harm in trying unless we're not sure how to do it.

Bad Side About Canon Cartridge

When I got my 1st Canon printer it was MP145. Then, after several years the scanner gave up. I tried to look for replacement but it's was so sad to know that it was faced-out in the market and it's hard to find some replacement. So, I turned to MP287 which is slightly different from MP145.

I really liked Canon model when it comes to speed printing. The 3 in 1 features is amazing too. Although the performance is great, there seems something bad about it - it's the cartridge.

The cartridge doesn't seem to last for years and it sounds so expensive to buy a new one when out of ink or defective. Maybe that's how they made it. For this reason, many user opt to convert the printer into continuous ink system to eliminate that thing (replacing the cartridge often) or save money and time in buying a new one. 

The Print Head is basically attached to the cartridge which make it more easy to replace or remove when the head is damage which is an advantage compared to other brand of printers. 

However, when misalignment happened during the printing process, you need to perform minor head cleans which solved the problem but the fact is - doing too much (when no prints appears) can totally damage the head which means we need to buy a new one (in case of using original inks) or some fresh empty cartridges (in the case of using continuous inks system).

Using original inks cost a lot if damages occurs to often. And this is a great disadvantages of using canon printers. The same thing feels when using a continuous ink system (CIS), even though fresh empty cartridges is way much cheaper.

Putting Waste Ink Tank In Canon MP287

If you're planning to make your Canon MP287 ink pad dry and clean, you better put a waste ink tank. It will help better dispose such waste inks without any mess. By so doing, you can also save and use waste inks with your refillable Pilot pentel pen. Yes, I use waste inks with Pilot pen.

Here is the simple way in placing waste ink tank removing only the back cover. Be careful when pulling the cover, there's an additional lock on the flip side of it which may easily broken.as shown in 3rd image. So slightly pull it off using a long flat screw driver.
