Since Canon in maybe 2008 introduced chips in both single ink tank cartridges and combined sponge and printhead cartridges, it has been possible to print with cartridges that have been declared empty and then refilled. You could disable the ink monitoring by pressing and holding the stop/resume button for five or ten seconds when the warning that a cartridge was empty was shown. You could now continue printing but without ink monitoring for that cartridge, and you were warned that this action was stored in the printer's memory and the warranty was lost.
This disabling of the ink monitoring as mentioned
in the link in my previous post has worked for me with printers using cartridges as new as PGI-550/CLI-551 and PG-510/512 and CL-511/513. The link mentions PG640, PG640XL, CL641 and CL641XL as also compatible with the procedure. I wondered if this was a typo so it should be PG
540(XL) / CL
541(XL)? which are for use in Europe. The PG
640(XL) / CL
641(XL) are identical except being intended for use in Australia and New Zeeland.
I noticed the link is to an Australian site and early cartridges and printers used the regional coding for Europe, region 5. Later Australia and New Zeeland got their own regional code, region 6. But why could the ink monitoring for PGI-x40/CLI-x41 cartridges be disabled in Australia and New Zeeland but not in Europe?
The MG3650 uses a newer cartridge generation than the PGI-550/CLI-551 and PG-510/512 which could be disabled, the PG 540(XL) / CL 541(XL). Maybe you can no longer disable ink monitoring with printers using these cartridges? But then it should be impossible to sell remanufactured PG 540XL / CL 541XL cartridges? But you find many sites selling these remanufactured cartridges. Did the cartridges come with an instruction telling how to use them?
I checked the
Windows user manual for the printer, and found nothing about disabling the ink monitoring. There are only some error messages in case a cartridge is defective or not recognised, and if so the cartridge should be replaced.
HP is using some nag screens when you install a refilled cartridge, but at least when closing these annoying pop-ups you are allowed to print. Can you close the error message that the Canon cartridges are not original and then print?
If you find a solution please post it. Else I suggest to contact the seller of the remanufactured cartridges.
