My MAXIFY 5350 is on refill ink

[steven.va]

Hi Palombian,

It seems like. (no visible locking problems to see however)
Opened the side of the printer.
Disconnected the connectors on the top one by one.
Printer would boot, with different error codes depending on what whas diconnected.

Found 3 cables to the scanner / enconder had slight moisture damage.
(do you remeber I found this printer dumped 3 years ago - I bet it got rained on/sat in the rain)
Cleaned the connector with isopropyl alcohol. Look okay for now.

Let it all dry.

I am now greeted by a 6700 error on bootup.
The closed I can find, that this is a battery error?
And that there is a reset tool for this?
(It does have a battery inside I have seen)

Greetings.

Just a note to myself.

I probably disconnected the flat cable that connected the RTC board to the main board.
I'll try the recovery tool, to correct my error.

Do not unplug the connector labeled BIND on M/B in Maxify w/o pluggin unit in.

Steven.

That could be the problem, because if the printer was not plugged into the power socket at the time.. But doesn’t need to be powered on...

Hi

,@The Hat
Thx for your reply. Indeed, that's exactly what was happening.
A bit of searching through the forums got me the answer.
(I wonder, one should not use a power strip to turn the Maxify off at night
in order to conserve battery life - since it's such a pain for an end user - bricks the machine)

Update;
Fixed my mistake.

Enter service mode like this video shows (Korean video, it but shows it clearly)

I used tool ST-4905
Click Other -> Operation -> set time
Done.

Printer not fixed, just back to first symptoms/fault (good)
Having that fixed ...

Troubleshooting session #2
I know now it's not the scanner!
The CPU is crashing 15 seonds after startup, and 5 s after chrashing the WDT kicks in and resets the machine.

The poor little scanner moter keeps turning becaus the software has crashed, and it cannot count the pulses
anymore from the encoder wheel (can be seen with a flashlight on the right under the glass plate)

More updates to come later (I hope)

Steven.

This proves again setting the timer with the appropriate service tool solves the battery error.
Good luck with the scanner !

Concerning my Maxify, refilling OEM carts with the Canon bottled ink for the ecotank version works very well.

The only issue still is contamination of the color with the lowest level if not used regularly.
We have no clue how the pressure is set in new carts.

I solve this by printing plain pages in high quality of the affected color until good again.
This way the ink does not fill the waste pads as with cleaning instructions.
As long as the contamination is limited to the ink reservoir in the printhead this is the best solution I found (but it can make its way into the cart too).

Dear printer friends,

Since a few months I was struggling with stripes in the magenta, cleaning didn't help.
I thought I ruined the printer by neglecting the ink low message and decided to mount a new printhead.
(FYI you need to remove 2 screws before you can lift the handle)
But by inspecting the printhead I saw a lot of smudge on it. I wiped it of and tried to remount the old head.
As by wonder the nozzle checks were almost flawless again (apart from some contamination in the yellow, IMO the largest problem when refilled carts have a different ink level).

The Maxify is a very sturdy printer.

I use the Canon GI-56 bottles for the GX Maxify's to refill my MB5150.

I use the same inks on mine but get a better colour output than your, ? click to enlarge

I think @palombian 's magenta and yellow are still contaminated. Hopefully the contamination will go away after a couple of nozzle cleanings or after some use.

Indeed, once you get cross contamination it is difficult to eradicate due to the buffer in the printhead.
I'll try to print lots of pages full of magenta and yellow (better than filling the purge pads by cleaning cycles), but maybe I should change the carts.

PS: I refill only when the autoreset chip indicates an empty condition using the "official" cartridge removal.
I hate the power plug pulling trick, and you don't know the correct ink level anymore.
But I agree it causes cross contamination in particular when you don't print a lot immediately after cartridge changes.
Maybe this is a greater disadvantage than the incorrect ink level.

I threw in the towel after getting bored with cleaning and troubleshooting and bought a laser. Maybe I'm just too old now to spend time fixing print problems but the volume of printing I do these days is so small that a laser makes sense. If I don't print for two weeks and then print something it just works. Not good for any photo printing of course but the Maxify is not great for photos either. It served me well for 7 years so no complaints, I think it is still the best value AIO inkjet printer out there. £139.99 for 7 years service is OK
