Urgent: How to Bring Back the Canon MP280 to What It Once Was after CISS Conversion to Get Rid of E14 Error?

[James Mike]

The EEPROM save function will probably give you a softcopy of the CURRENT contents of the EEPROM which would be then edited in a hex editor to have your desired changes made before being flashed back using a hardware programmer.

Do you still have the instructions for your CISS conversion ? Most kits and conversion services offered local to me doesnt involve the use of the service tool upon installation and the only time it would be involved is to reset the waste ink levels. Owners would just be instructed to disable ink monitoring whenever the printer gives an out of ink error.

A quick perusal of the service manual for the MP280 seems to suggest that even the EEPROM clear action SHOULD NOT touch the ink region code without a separate flag set prior to using that command. Your Instructions may include steps that allow that to happen within the service mode program (which would not otherwise be allowed as stated by PeterBJ and personal experience with service mode 3.4 and a MG6270 printer)

cartridge with the 810 series (along this number that starts with 8).

Your printer is likely to be configured to use CL-811/PG-810 carts for the asian region printers

The EEPROM save function only saves some of the clear text info from the print EEPROM function, in a text file that can be opened in notepad, no hexdump is saved. I have had both an MP280 and the very similar MP495 and here is the saved text file from the MP495 EEPROM save:

The first service tool in post #8 is v1.074. Versions after v2.000 hasn't got the EEPROM clear function.

The service manual linked to by James Mike is only supplemental. You also need a manual for the base models as there are many very similar models of these printers. The base models service manual is here: https://elektrotanya.com/canon_pixma_mp240_mp245_mp260_mp268_mp480_mp486.pdf/download.html

Your Instructions may include steps that allow that to happen within the service mode program (which would not otherwise be allowed as stated by PeterBJ and personal experience with service mode 3.4 and a MG6270 printer)

I read something on the forum about a factory mode which is different from service mode. I will try looking for this. Maybe cartridge region setting could be changed from factory mode and an EEPROM programmer should then not be needed?

Could the original Canon CL-210 and CL-211XL cartridges be used and probably defective?

I think the problem is caused by mismatched printer and cartridge regions, so I would like to know where you are located, where you bought the printer from, where you bought the CIS conversion kit from and where you bought the original cartridges from. You don't need to give your exact location, the Canon region would be sufficient.

Without this info I think we cannot solve the problem.

I found the posts about factory mode but they don't tell if they can extend the capabilities of the service tools. Link here to the first of three posts. It doesn't seem to be of any use here.

Hi, thanks for the information. I guess there's a region lock, even though the cartridges and printer are physically the same, the 210 and 211 as you've mentioned are for the US version of the MP287 called MP280 (changing the region to US using the 3400 resetter didn't work). I did ask the seller if I could get a refund but he can refund it with less coz' it's been open and used a bit to print (about 8 tests) the test page printout on the resetter.

He most likely won't refund, coz' the window is way past the refund (I only got to check this out thoroughly just now coz' of the projects and then some in the past few months).

I wanted to ask is there's a way to transfer my current PG-810 and CL-811's chips to the 210 and 211XL cartridges with a hardware mod/hardware hack?

Thank you. God bless printer experts.

Sadly no, Unlike the single ink tank cartridges which have the chip on the outside of the cartridge, so it is easily exchangeable, the chip is internal in the combined sponge and printhead cartridges, so it is not accessible.

Hi, not to worry, I've open these types of cartridges before, I'd like to try to mod it (I have experience at hardware modding (carbon fiber, sealant things, Dremel rotary tool, digital calipers), I'm a kind of maker on the side (but nothing in the level of Adam Savage of Mythbusters).

Is the chip inside the plastic infront where the heads are? I could open them up, all four (coz' I don't think I'll be able to refund this anyway, no way to sell them too coz' it's for the US region).

I'd like to try, it's a risk but a calculated risk.

Thanks.

A printhead is a large scale specialized integrated circuit or "Chip". As there are no separate ink tanks in a combined sponge and printhead cartridge I think that cutting open the printhead section will reveal no separate region and ink level chip. I think that function is a part of the control logic of the printhead.

Here is a 250 times magnification of a part of the control logic of a PG-510 cartridge, click to enlarge:

I'd probably siphon the ink from the US carts and transfer them to the correct cart (or even transfer the sponges if one is okay about opening and resealing them) rather than try to swap the chips on that kind of cartridge.

I don't think people knows where the actual region/level chip is within the cart(nor if it exists in the same form as in the ink tank style cartridge) or have a use for that knowledge as it is soldered, likely encapsulated if not embedded deep within the plastic body like the actual printhead. Even in the best case scenario that the chip is exposed and located in an accessible location the soldering work required precludes alot of people from being able to swap that component directly. Instead a new chip is overlaid on the flex cable for ink monitoring. Not sure if it will work for your purpose of changing regions nor if it works more than once(or at all).
