Canon Pixma iX6850 Ink Cartridges

Our PGI-550/CLI-551 Multipacks do indeed contain both a PGI-550BK and a CLI-551BK cartridge.

The PGI-550 Black is a larger capacity than all of the other cartridges and is used in general printing and text documents. Especially handy when requiring crisp, sharp text documents. The CLI-551 Black is used mainly in photo printing to improve the richness of the finished print and is sometimes referred to as a Photo Black.

Our Canon compatible cartridges were recently voted No.1 in Which? magazine when judged on quality and value for money so they come with high recommendation! All of our compatible cartridges for Canon printers are extensively tested during manufacturing to match as closely as possible to their Genuine counterparts in both reliability and quality.

Most cartridges have an outer plastic wrapper that needs to be removed first and foremost. Secondly, you should see a plastic tab stuck to the cartridge. This is usually Black and Yellow and has the word 'Pull' or similar marked on it. This tear off strip needs to be removed next. After that has been removed it is then safe to remove the plastic nozzle cover, but it is imperative the instructions are performed in the correct order to avoid spills or leakage.

We also recommend carefully removing the nozzle cover with it facing upwards towards you in order to further prevent the risk of spillage.

Once the cartridge is fully open it is then ready for installation.

In the event of an error after cartridge installation, the first thing to check is which cartridge or cartridges are showing the error. Your iX-6850 printer display should show a graphical representation of any cartridges that are not recognised.

If two or more cartridges are not recognised please check they are all installed into the correct cartridge position in the print head. If only one cartridge is showing an error it is worth removing to check the chip is clean and fully attached in the correct position, before reinstalling to make sure the cartridge is seated correctly.

This is a common issue and usually occurs when the plastic tear off strip has not been fully removed before installation. Until the tear off strip is removed, an airlock within the cartridge will prevent ink from flowing correctly.

Please check the plastic strip is fully removed before installation and that no sticky residue is blocking the air hole. If this does not solve the problem, please contact us for further help.
