Can all Canon ink cartridges with print-heads on the cartridge be refilled?
Refilling Canon ink cartridge such as the; PG30/40/50/210 and CL31/41/51/211 is easy and simple. These cartridges don’t require a chip and it takes a few minutes to clean the print-head and refill both the black and color cartridges. While physically you may be able to refill them, you may experience recognition issues due to the following reasons:
1. Main reason is the Fax function. Canon printers combined with fax function seem to reject the cartridge every time and give a message of error requiring replacing cartridge with a new one.
2. Regardless if the printer has a fax function or not, if the printer already registered the cartridge you refilled as empty rather than detect as low in ink; you will be force to replace the cartridge with a new one.
You can refill all PG30/40/50/210 and CL31/41/51/211 but they will not work with canon printers which have fax functions, but will work on all other canon printers compatible with these numbers.
