Your printer/computer may display ink alert messages, such as “remaining ink cannot be correctly detected”. Press “OK”, “Yes” or “Close” to dismiss alert prompts, or press “OK” on the printer. If you refilled your ink cartridge at one of our retail refill labs then the Canon cartridge chips should have been reset via the Canon C2 Resetter (special photo lab equipment) and ink level monitoring will be available – you may disregard the information below unless you observe flashing lights or low ink error messages. If you need to manually bypass the alerts then perform the following steps.

 

NOTE 1: “Low Ink” and other ink cartridge nuisance messages are COMPLETELY NORMAL for all Canon 250, 250XL, 251, 251XL, 550, 551, 550XL & 551XL  ink cartridges (tanks) which have been refilled and installed into the printer!  While at first this may be considered an unusual workflow, it does allow print operations to proceed. ‘Grayed-out’ ink tanks will be displayed on the LCD screen or Windows pop-up screens when ink levels are checked – this is NORMAL.

 

ACTIVATING REFILLED INK CARTRIDGES:

To activate refilled Canon ink cartridges (and resume printing), simply press the “Stop/Resume” button (down arrow/triangle-circle) on your printer, for 5-8 seconds, until the low ink indicator goes out, the power light stops blinking and the printer resumes printing.   ‘Red X‘ cartridge empty indications should then disappear from Windows prompts/messages.  Repeat procedure when each refilled cartridge is installed into printer. Refer to video below.

For printers that feature a LCD/Touchscreen (i.e. Canon MG6320 printer, etc.), then select ‘Touchscreen Printer Reset Procedure’ button below to enable the refilled ink cartridges:

Touchscreen Printer Reset Procedure

 

Additionally, your printer or computer may display ink alert messages, such as “remaining ink cannot be correctly detected” or “printing under the current condition may damage the printer”. Press “OK”, “Yes” or “Close” to dismiss alert prompts, or press “OK” on the printer, so that the printer resumes its normal operation. These types of annoyance messages will randomly appear and should be expected when using refilled ink cartridges. Refer to video below for more information.

NOTE 2: If the printer is allowing copies to be made, it should mean that the tanks are not at the “ink out” level that requires the clearing of the ink level indicator by holding down the Stop/Resume button.

NOTE 3: Received faxes which are stored to memory will not be printed – though you can manually print out any fax contained within memory. You can change this setting to forcibly print all incoming faxes.

 

Canon 251BK/251XL BK/551BK/551XL BK (Photo Black) Refilling Tip: 

You will need to ensure the Canon 251BK / 251XL BK / 551BK / 551XL BK (photo black) ink cartridge is really empty before bringing in for refilling, otherwise the cartridge may be ‘rejected’ by your refiller. Photo Black is only used when printing photos so this color will typically last much longer than the other colors.  If the cartridge is not completely empty, an accidental overflow of the photo black ink cartridge may occur during refilling. Under the printer’s Maintenance menu, activate the internal self-test print (i.e. Nozzle Check) to verify which color, or colors, are missing.

You may activate the Nozzle Check from either the printer’s LCD maintenance menu or from the Windows printer driver menu (iP printer models):

 

NOTE 4: Canon does not allow an automatic reset of the electronic chip on the cartridge after a refill, so the ink level indicator is sending a false message that the ink level is low. Your cartridge is not low on ink, and nothing is wrong with your printer or cartridges. The ink level indicator usually cannot be manually re-set, so the ink level indicator is often not usable. However, losing this feature is not necessarily significant, because the ink level indicator usually has substantial usable ink remaining when it shows “low on ink”. Ink level monitoring is primarily for planning purposes only – it is not required to support printing.

 

 

The Canon PRINTHEAD will eventually fail over time with usage and age (may or may not be replaceable – refer to User Manual)*

HOW TO REFILL

*Typically the Canon PRINTHEAD (which is customer replaceable in many higher-end Canon models) should not reach it’s end-of-life until after a minimum of 10 or more complete sets of cartridge changes. While some printheads may last 15,000+ pages others may only last 3000 pages, actual results will vary. The printhead will eventually fail in time from an internal micro-electronics failure due to the following leading factors: general customer print usage and printer care, printer duty cycle (i.e. # pages printed per month), printing frequency (i.e. time between each print job), print mode (i.e. draft vs. normal) and content printed (i.e. photos vs plain pages) and color mode (black and white only vs. color/greyscale printing). Paper types used (i.e. plain paper, photo papers & matte/heavy bond papers) and paper edge curl (due to age in printer or low relative humidity) can also quickly lead to premature printhead failures due to physical ‘head strikes’ of the paper edges making repeated contact with the printhead nozzle plate.
