Before you start

A printhead that has been starved of ink for a long time may have burned out by firing air instead of ink. New seals will not bring it back.
Even after a short starvation, the ink bladder inside the printhead can collapse too far to refill, leaving the printhead permanently starved.
A poor electrical connection between printhead and carriage can look like a failed printhead. Clean the printhead contacts and the carriage contacts until neither feels tacky.
If the drop detector is covered in ink overspray, the printer will not finish print system setup even with perfect printheads. Clean the sensor.

Returns

Before You Start: Key Considerations

Some printheads can be fully recovered; others may have sustained permanent damage. Here's what to evaluate before beginning:

Long-term ink starvation: A printhead that has been running dry for an extended period may have burned out from printing with air and will not respond to seal replacement.
Collapsed ink diaphragm: If the internal diaphragm has deflated too far, ink may not re-inflate it, leaving the printhead permanently starved.
Poor electrical contacts: Dirty or tacky contacts between the printhead and carriage can mimic printhead failure. Clean both surfaces thoroughly before concluding.
Drop detector sensor: Ink overspray on the drop detector can prevent the printer from completing print system setup, even when printheads are functioning correctly. Inspect and clean this component as part of your process.

UPDATED Printhead Recovery Kit for HP 91, 731, 744, 774, 746, 771 Printheads

FINALLY A Reliable Lifeline!

I called LPS after finding their number online for a large-format HP printer. The person I spoke to was incredibly knowledgeable, and led me directly to the correct product. They even had a step-by-step tutorial, and he said I can call for help anytime. They've earned a customer for life!

One of the best companies to work with!

It is always a pleasure doing business with this company. Tim and Bob are always eager to help when needed.

Print Head Kit

Haven't had the opportunity to utilise the kit yet, awaiting some replacement print heads. However, the product supplied looks to be good quality. Not sure if the replacement seals will eventually find their way into the towers or not; nor if they are changeable to any subsequent replacement print head as the issue is not really with the heads but the seal within the towers.

Eagerly awaiting the opportunity to get the Z6200 up and running

Look no further!

I had a printer that had been sitting outside in the sun, and I’d been searching for a solution like this for a while. I finally found this product and decided to give it a try.

I own an HP Latex 560, which uses the 831 printheads, not listed, but identical to those on the Latex 360. Everything worked flawlessly! It brought two printheads back to life that I was sure were done for, and even revived both optimizer printheads. I’m honestly speechless ,100% worth every penny.

Before ordering, I reached out to confirm compatibility, and their response was fast and helpful. Processing and shipping were also impressively quick.

Overall, I couldn’t be happier with this purchase.
