Can Compatible Ink cause Print Heads to Block

Reply to Question on Printerknowledge Forum

Some years ago there were real problems caused by ‘cogation’, the deposit of dried ink on a thermistor in a print head. As a supplier of compatible cartridges we had to replace a number of print heads, mainly for the Canon BJ300 and 800 printers. We believe Canon had this problem too.

Bad ink can still cause problems. Most ink is good – but I have heard many horror stories, mostly from China. I always recommend that users go to a reputable supplier. They know which are the good Chinese manufacturers and these use good ink.



My company was once Europe’s largest master distributor of compatible inkjet cartridges, bringing in 160,000 units every week. Now, Incartek sells a full range of cartridges for Epson and Hewlett Packard, manufactured by Ninestar (G&G Brand). Ninestar is probably China’s best resourced company in the supplies industry.
