The HP Officejet Pro 8600 Plus is identifiable by its model number: N911g. Released in 2011, the printer can be identified by its brown finish and touchscreen control panel.

How do I replace or refurbish the ink absorber?

The ink absorber is full and leaks black ink. Questions:

  1. Does anyone know of a source for the replacement part?
  2. How do I remove the ink absorber?
  3. Can the ink absorber be refurbished?

You can remove it but HP is infamous for making them smaller than even Epson and Canon are now (even with chipped pads). Yours isn't terrible - yours uses the service station assembly so you do not have to touch waste ink (yay!!!) but your also costs more to repair because HP has the service cap and motors in it and it adds cost (BOO!!!). The HP P/N is CM751-40001.

However, HP machines are a proper predicament to repair - unlike even the Epsons and Canons of the world with weak pad capacity, the procedures are KNOWN well enough we know the common ways, or we can get a leaked copy of the Canon/Epson service tools to repair the printers. HP doesn't have this and the procedure to reset is unknown. They skirt having to disclose this by replacing the printer and taking advantage of RtR laws that exempt the Amazons of the world from giving us the info by "replacing the product", so you also have a hard time finding the part. Unless it can be reset in the manufacturing mode or you can do home>? ~7 times (? 7 times brings up the support menu to do things like cartridge region swapping) you can't reset it due to the Amazon sized loophole HP has used for years. Yours nay never shut down but it’s a risk you run unless you reset the counter.

It may also be triggered by the following:

Home 3x (reads like a support menu, may not be useful)

Cancel>Resume>Cancel>Resume (support or diagnostic?)

iFixit has some guides for this but there's no info on how to bypass the ink system shutdown as HP has a real counter on these, whereas previous 564/920 machines were just allowed to flood with waste ink and you didn't have to mess with the WIC counter. It's not looking good in terms of finding a service manual.

@oldturkey03 I’m going to see if I can find a SM for this one but I’m laying out what I know right away. I know I throw a good bit of shade at Epson for reducing the pad size after the R200 series but HP is bad in comparison. Not looking good, HP's replace the product loophole makes manuals a PITA to find :-(. Probably a lost cause because old product+RtR loophole as HP replaces the entire printer.

BS like this is why we need to close the Amazon loophole and device lifetime loophones. Why can't I find the SM, parts or reset tool for no reason other then HP being greedy? Yes, Canon and Epson require leaks but I can buy the tool or download it from Megaupload or other sites not obligated to follow the DMCA.
