Printhead Replacement Incomplete on Designjet T and Z Printers
Posted by Tim Wert on
This problem occurs in the following Designjet models: T610, T620, T770, T790, T1100, T1120, T1200, T1300, T2300, Z2100, Z3100, Z3200, Z5200, Z5400.
Your printer is in the middle of "preparing print system," and after 20 minutes of waiting, it displays the message "printhead replacement incomplete." You power the machine down, and back on, and it still tells you "printhead replacement incomplete." Very often, this is caused by insufficient ink supply. If you are using non-HP brand ink cartridges, install new HP cartridges. If any of the ink cartridges is below 40% full, replace that cartridge.
If there are any pockets of air in the ink tube system, the machine may display a "replace ink cartridge" message. Air in the lines is another possible cause for the "printhead replacement incomplete" message. When the ink supply station compresses the air in the ink cartridges, if the DC motor driving the pressization piston doesn't detect enough resistance, the machine interprets that signal as either an empty ink cartridge, or a faulty ink cartridge. In either case, the printer will not complete preparation of the print system, resulting in the "printhead replacement incomplete" message.
For this reason, it is recommended you purge each of the ink delivery lines, using the universal priming tool.
**IF THE INK TUBE SYSTEM IS COMPROMISED, YOU WILL NEED TO EITHER REPLACE THE TUBE SYSTEM, OR DO THE EASIER AND CHEAPER FIX OF INSTALLING THE SEAL UPGRADE KIT.**

HP T1300. All 6 cartridges are over 50 percent. It keeps cycling through the Preparing Print System, back to 7 minutes, down to zero, back to 7 minutes.
Thanks, very informative !
I have a T610 where it keeps asking me to replace Magenta ink cartridge.
I started off after there is a ink leaking on Magenta along the printing path. It shows ink cartridge faulty after that. Leaked ink has cleaned up. But after replace new ink cartridge, it printed about half a page, end up Faulty M ink cartridge again. So far 4 ink cartridge have replaced.
Technical checked that there is no ink leakage that could short the ink cartridge chip set.
Can someone please advise?
