If your HP B210a has a clogged printhead, this guide can be used to try and clear the clog.
'''IMPORTANT: While there are no guarantees this will fix the problem, this will fix most printers. This fix also depends on the printhead being recoverable, so this will not work to recover a printhead with electrical problems. This fix will not work 100% of the time. If this fix does not work, it's generally better to replace the printer and not the printhead.'''
== Guide Notes == * '''WARNING: THIS PROCEDURE MAY DAMAGE PRINTHEADS WITH PREDISPOSED DAMAGE. If the printhead has failed, it was likely caused by predisposed damage.''' * This guide is primarily made for the HP Photosmart Plus B210a, but is universal among all printers that use the 564 ink cartridge. '''IMPORTANT: Models with nonremovable printheads require special attention to preserve the calibration. These models may not work again if this is lost and SETUP cartridges are expected.''' * If I have not tested the printer you are having problems against my calibration preservatio procedure, I do not guarantee that you will be able to preserve itn. It generally doesn't hurt to tryon models with removableprintheads , but Ican't guarantee it will workunless I have tested it personally . === PrintheadBypass model list == '''Validated models (known to work)'''=
