Introduction
If your HP B210a has a clogged printhead, this guide can be used to try and clear the clog.
* ***IMPORTANT: ''This does not fix every printer. These steps will not work on failed hardware!''***
* ***Note: ''If the problem persists, it IS due to a hardware problem.'' Replace the entire machine, the cost to swap the printhead is more than a new one.***
=== Guide Notes ===
* ***WARNING: ''THIS PROCEDURE MAY DAMAGE PRINTHEADS WITH EXISTING DEFECTS! Use caution if you suspect an HW issue that could be made worse and finish off the machine, or write it off before trying!''***
* This guide is primarily made for the HP Photosmart Plus B210a, ***and other REMOVABLE PRINTHEAD configurations with HP 564 ink cartridges.***
* ***''Non-removable printhead models (Ex: Photosmart 6520) require special attention to preserve the calibration. These may not survive a lost calibration if SETUP cartridges are required.''***
** ***''If I have not tested your printer, I cannot guarantee the calibration preservation procedure will work.''***
** ***WARNING: IF YOU TAKE AN INTEGRATED HEAD PRINTER APART, YOU MUST KNOW HOW TO GO INTO THE FACTORY MODE AND BYPASS THE SETUP INK REQUIREMENT OR BE PREPARED TO THROW IT OUT! NOT ALL UNITS HAVE THIS!***
=== Tested models for head setup bypass ===
* Photosmart C6380
* Photosmart Premium C309g
* Photosmart Plus B209a
* Photosmart Plus B210a
* ***Note: This procedure should work on MOST of these, but getting it wrong nukes the stored alignment (and youryou will need new ink cartridges). Pay close attention unless you can buy a set of ink if you miss it.***
