Q: - How to avoid clogging pumps in wide format printers?

Understanding the problem: 

Easy solutions for difficult or huge problems can be found often in small adjustments but first you need to understand the problem. You already have accepted (you should)  that water based pigment inks dry faster as any other type of ink. You also understand, most printer designs can create additional bottlenecks to avoid the flow of the ink smoothly.

Many printer operators may starting cleaning cycles because of the reduced performance of a print head ending in frustration where the problem may lay in the design of the printer.  Remember that our  water based pigment ink is designed for piezo technology and if the printer is in a good condition clogging heads should be very rare even if it is not impossible.

No, we do not want to redesign or to modify every printer type to suite the inks but small adjustments can have a great affect and improve the performance especial for those components of printers who may not have being designed for heavy duty purposes.

New printers also can come with components not in 100% good condition and therefore we urge you to run the printer for some time with inks recommend by the manufacturer. Print very often a nozzle check pattern and be very crucial when cleaning cycles are necessary to improve the performance. The printer may have a problem already and you will only ask for more problems by switching to an heavy duty ink such as pigment inks what includes a fabric binder.
