solution without needing to contact support. Proactive Support offers several benefits for the business such as

increase customer loyalty, decrease support calls, control communication, acquire new customers, retain existing

customers, create advocates and protect against escalation. It also presents the opportunity to meet and exceed

customer expectations, strengthen customer relationships, and boost the value of clients.

Passive Selector Valve For Dual Supply Ids, Hp Inc

Defensive Publications Series

One of the parameters of the IDS very valuable for our customers is having autonomy when

the supply gets empty. On this search of the optimal solution, an intermediate tank is usually

used, due to its cost. Another way of increasing the autonomy of the system when having an

out of ink event is having another IDS (having then two supplies) so you can consume ink from

the other one when having an out of ink event. However, this architecture is much more

expensive.
