This document is for the HP Officejet Pro 251dw, 276dw, and 8600 series printers.
note:This video shows an HP Officejet 8600 printer, but the steps are the same for your printer.
note:Do not remove the cartridges from the printhead. You can safely remove the printhead with all of the cartridges inserted.
caution:Handle the printhead carefully to avoid ink stains. Do not touch the underside of the printhead.
caution:Do not touch the electrical contacts or the nozzles on the printhead, which might cause electrical failures or print quality problems.
note:Make sure that the colored dot on the cartridge label matches the colored dot on the slot.
caution:Do not lift the latch handle on the carriage to insert cartridges. This might cause the printhead or cartridges to be incorrectlyseated, which could damage the print mechanism and cause printing problems.
note:Not all customers are requested to return the old parts. If the replacement printhead assembly came without a post-paid return mailing label, ignore the rest of this section.
