HP Designjet T/Z Printer Series - Printer Prompts for Setup Printheads After EEROM Reset
After EEROM reset, the printer prompts the end-user to install setup printheads.
NOTE: This document is not valid for all T and Z series printers. It is valid only for the T610/T620/T1100/T1120 and Z2100/Z3100/Z3200/Z5200. The other T series printers will not ask for setup printheads after performing EEROM reset.
Cause : When EEROM reset is done, the printer firmware resets the flag that indicates that the Ink Tubes Purging has been completed. This causes the printer to assume purging has not been done and to start the purging process.
NOTE: Follow the steps below only if it is confirmed/known that the Ink tubes have been purged successfully.
After the EEROM reset has been performed, the printer will have powered it's self off.
NOTE: This document can be followed only if all cartridges installed are new (100%) or if the ink volume remaining in every Ink cartridge is below 88% (cartridges between 99% and 89% may not work). On the other hand, the minimum ink volume remaining in EVERY CARTRIDGE must be 35 milliliters. Under the front panel/Ink menu/cartridge information, the percentage cannot be checked, ONLY the ink available in every cartridge. As a reference, the following information can be checked (40ml-cartridges WILL NOT work):
88% is equivalent (not exact) to 60.7ml
50.7% is equivalent to (not exact) to 35ml
88% is equivalent (not exact) to 114.4ml
26.9% is equivalent (not exact) to 35ml
NOTE: Even when this document has been created to trick the printer, this will not be possible if the cartridges are not valid (do not have the proper amount of ink even when in fact the ink will not be used for a real purge). If there is not enough ink, the printer will get stuck saying PRINTHEAD REPLACEMENT INCOMPLETE after the printheads have been inserted.
