The FINE Cartridge holder moves to the right.

See "Aligning Print Head - Auto head align" on page 53.
To maintain optimal print quality, we recommend that you use Canon brand
FINE Cartridge. Replenishing ink only is also not recommended.
Replace the FINE Cartridge promptly. Do not leave the FINE Cartridge
removed.
When a FINE Cartridge runs out of ink, replace the FINE Cartridge with a new
one immediately. If you replace it with the FINE Cartridge that has been
removed once, the printer may not print properly due to clogged print head
nozzles. And, the low ink warning message which relays the exchange time
of a FINE Cartridge will be off.
To maintain optimal print quality, the FINE Cartridge should be installed until
the "recommended date of replacement". And, use up all ink in the FINE
Cartridge within six months from its first use (We recommend that you take
note of the date when the FINE Cartridge is installed to the printer).
