Hi, I'm new to this forum, but have been designing/manufacturing continuous ink systems for HP large format and business/office jet printer for the past 8 years. www.inkbags.com is our company website. Here to answer any questions anyone has regarding inks / chips / cartridges etc. What products work and what to stay away from. Anything related to HP bulk ink systems, please don't hesitate to ask. Thanks.
After putting 2 litres of ink through our HP K5400, it's now pensioned off. I've struggled to get a CISS or refillable cartridges to work with the new HP 8100e. Even though the refillables are chipped, the printer knows they're not kosher and plays mean tricks like doing very poor quality printing on the second day. How can I get round this problem?
