Re: Canon scam: is there a useful hack to scan WITHOUT ink ? (Pixma MG 2550s)
so are there any printers without that flaw?

Re: Canon scam: is there a useful hack to scan WITHOUT ink ? (Pixma MG 2550s)
for reminder my initial intent is not to be able use the scanner while the ink cartridges are dry or empty, but to be able to use it [I]without cartridges [/I]
but I didnt know Canon cartridges dry out
what printer brands make cartridges that dont dry out? or is that a design flaw common to all printers?Re: Canon scam: is there a useful hack to scan WITHOUT ink ? (Pixma MG 2550s)

just a question if I flash a bad firmware - say, one where I modified some bytes at random (there's only 1024 of them anyway so the ink-detection function must be in there somewhere) - will the printer be bricked for good or is it possible to restore it by reflashing with the original firmware?Leave a comment:

but in this case aint it just a matter of altering a couple of bytes in this file? if so it's frustrating cause I can see the entire file on notepad cause it's so tiny yet I dont know what to edit :/
(btw I didnt expect the firmware to be contained in only 1024 bytes that dont seem much room to program something like a printer)...Last edited by Urizen; 12-29-2022, 11:28 AM.Leave a comment:

to actually work on firmware I'd have to learn assembly language right? I've done "high level" languages in the past like C but assembly is supposed to be a lot harder to learn
anyway I found this thread [url]https://www.badcaps.net/forum/showthread.php?t=92191[/url]
not sure what everything means but I downloaded service tool + the eeprom dump (that's the same as bios/firmware dump right?)
so this [B][I]suggests [/I][/B]it's possible to flash a bios...Leave a comment:

but if it's possible to flash a firmware to a device without opening it then isnt it automatically possible to also extract that firmware from a device without opening it? figures it goes both ways
at any rate I'll try find the firmware for my printerLeave a comment:

but even if I could get the firmware file somewhere I'd still have to open the device to flash it right?Leave a comment:

thanx I got it but if I understand correctly I need to open & physically manipulate the printer just to extract or flash the firmware ? +_- that's the first time I hear of this cause for other devices like mainboards GPUs & routers we dont need to do that...Leave a comment:

tried that though it's not clear what he did
hold "stop"
hold "power"
release "stop"
press "stop" 2x
release "power"
(w/o explaining what that's supposed to do)
but then he presses "power" again & the printer is supposed to try print? my printer just goes off
I also tried doing the first step but by pressing "stop" either 4x or 5x

lesson learnt but for this 1st round it's too late :/
anyway I reckon it must be just one line of code in the firmware which essentially says [I]"if printer not ready then scanner cant run" [/I]
so in theory someone firmware-savvy should be able to find & delete this sh right?
for starters how to I "extract" the firmware? (assuming it's possible for these printers which is a standard usb printer btw)Re: Canon scam: is there a useful hackLeave a comment:

so is there a workaround? a part of the firmware that could be changed or something
when the old cartridges went bad I threw them away and I dont want to buy new ones just to scan (and the closest commerce that sells this sh aint even close)Leave a comment:

the button with the red circle & triangle? tried that it doesnt work the orange blinking light still keeps blinking
nb. it's not just that the printer's without ink but it's also without ink cartridges (the 2 slots are empty) I reckon your method maybe works when there's already cartridges in the printer...Last edited by Urizen; 12-26-2022, 07:30 PM.Leave a comment:

Canon scam: is there a useful hack to scan WITHOUT ink ? (Pixma MG 2550s)
title says it all
I've a Pixma mg2550s printer/scanner All In One
when I try to scan but there's no ink cartridge it gives an "error code 2,140,21"
scanning requires no ink so it's obvious this is a scam basically an artificial block they put in place for $ reasons
so how do I bypass this? is there a hack? maybe a fixed firmware
nb. got this new Pixma at a bargain price but I defo wont be buying another Canon product if there's no fix for this "feature" -

Looks like a big forum.
so anyway I'm a tech newbie. aint much else to add really.Last edited by piernov; 01-02-2023, 09:39 AM.Leave a comment:
