  • $ 4898

If your printer is plagued with the message "printhead replacement incomplete. Restart it." then this is the kit for you. 

Includes:

-Upgraded purge tool with depth-limiter

-12 custom printhead seals compatible with all HP 70, HP 72 and HP 73 printheads

-Seal installation tool


If you own a T or Z printer, you've almost certainly seen this message: Printhead replacement incomplete. Restart it. And you can't print anything, because the printer isn't happy. This kit will save you hundreds of dollars on replacement printheads and ink cartridges. 

 

*Ink starvation of the printhead caused by poor seal at printhead port*

This is the main reason you see the "printhead replacement incomplete" message. Here's what happens: The printhead is starved for ink, fails to put ink through the drop detector -> results in failure   to complete print system setup, and the printer returns the "printhead replacement incomplete" message. You've probably endured the long, annoying process of getting the printer to accept printheads. Printheads which may be perfectly good, but due to worn seals on the ink tube system, the printer cannot accept the printheads. The seals in this kit solve that problem, permanently. 

To address this problem, first step:
Simply remove the production print heads, insert the tool and draw out ink and air bubbles. The tool can be used an infinite number of times and is a very handy tool for technicians and end users.

Next step:

Use the purple tweezer tool to install the printhead upgrade seals onto the printhead needles. Re-install printheads into the printer, and allow the printer to complete "preparing print system." 

Once the printer has run printhead alignment calibration, the printer will be ready to go to work!

A few considerations:

-If a printhead has been starved of ink for a long time, it may have burned itself out by printing with air instead of ink. If this is the case, that printhead will not recover with the installation of new seals.

-Even if a printhead has been starved for only a short period, if the internal ink diaphragm has deflated too much, it will sometimes not allow ink to re-inflate it, and the printhead will remain permanently starved.

-Sometimes the electrical connection between the printhead and the carriage is poor. Make sure to clean off the printhead contacts as well as the contacts on the carriage. If either of those surfaces feels tacky, you've still got cleaning to do.

-If the drop detector sensor is obscured by ink overspray, it will not properly detect the ink droplets, and the printer will not complete print system setup even if the printheads are working with perfect quality. The sensor may require cleaning.

The Purger Kit and Seals saved our bacon

The Iowa State Fair only days away and we’d stocked up on inks and the various rolls of media to run through our Z6800 but when we started sending the art files, the yellow was not flowing. We tried everything and then ran across the videos from LPS showing how to purge air from the ink lines with their tool and how to insert their seals to ensure an air tight connection from ink lines to print head. I ordered the Purge Kit and Seals and they arrived two days early. With the tool we were able to follow the steps in the video to purge air from the lines and fix the problem. Thank You LPS

Auxiliary Printhead Seals and Purger Kit

As an artist, a substantial part of my income comes from selling prints of my artwork produced with a Designjet Z2100 Photo.
The cost of inks for this printer and the low speed of the printer are compensated by the fact that I have developed a way of consistently printing with high quality on a 380 gm offset couché cardboard that is much cheaper than any equivalent inkjet paper.
Recently, however, the printer started loosing ink onto the starweel rail cover, due to deteriorated inkport seals (where the print heads connect). Because I couldn’t ´find a technician able to solve the problem, I was considering replacing the damaged inkports with the four extra (unused) inkports on the carriage train, but I was in a hurry and not sure I would succeed…
Thanks to your brilliant Upgraded Printhead Seals the problem was solved in no time and the Z2100 is back in business, as usual.
Thank you for the great service you provide us.

Didn't work for me

Clever product, but after several attempts, it didn't fix the "printhead replacement not completed" error. Sadly, I'm going to junk the printer.
