Inktec Refilling Instructions for
Canon CLI-521BK
Black Ink Cartridge
(BKI-9021D)
designed to work with genuine Canon cartridge only
GENERAL INFORMATION FOR SUCCESSFUL REFILLING
1. Appropriate timing and method for refilling
- Please try to refill as soon as the ink is exhausted.
If you keep on printing, even though the ink is already exhausted or neglect the cartridge for a long time, the nozzle will
be dried up and the cartridge will not be suitable for refilling.
- When printouts are getting unclear because of the ink exhaustion after normal usage, refill the
recommended volume of ink.
If you insert too much ink or fail to close the ink injection hole completely with the rubber plug after refill, too much air
may penetrate the sponge inside the cartridge and ink may leak through the nozzle, causing abnormal printing.
For stable recycling/refilling of the cartridge, it is recommended that you refill ink according to the user manual before
the ink in sponge is completely exhausted (dried up).
EMERGENCY MEASURES WHEN PROBLEMS OCCUR AFTER REFILLING
- When ink does not come out through the nozzle, or printouts have white lines:
Reason:
Because you have kept on printing with no ink inside the cartridge or ink is not sufficiently supplied into the sponge.
Solution:
- Repeat steps 1 to 3 in the user manual and wait over 2 minutes until ink is fully absorbed into the sponge. (More time
may be necessary as the sponge's ink absorption gets slower with repeated refills).
- Clean the excessive ink around nozzles with some sheets of soft tissue. Then install the cartridge in the printer and
run the "head cleaning process" before use.
- When ink leaks through the nozzle, and colours are not printed normally:
Reason:
Because you have injected more than the recommended volume of ink or the ink injection inlet is not closed
completely with the rubber plug.
Solution:
- Make sure that the ink injection inlet is closed completely with the rubber plug on the top of the cartridge.
- Keep the cartridge on some sheets of dried soft tissue for about 10 minutes. If the leaking stops completely, install it
in the printer and run the "head cleaning" process before use.
