I have an OfficeJet G85 that is leaking black ink. It is all over under the printer, and yet the cartridge itself does not look like it is actually leaking. It is very clean, but I know that ink had to come from somewhere. I am not sure what is going on or what to do about it. I did a search and thought there was an old post about this, but the links from the search won't work. Thus the new post. Thanks.

If the leaking is on the right, the service station has overflowed. After disassembly I suggest using a garden hose set to a trickle to wash out the bottom of the printer. Avoid getting water on the carriage, electronics boards, and motors.
You will need T10 and T20 Torx drivers.
Preliminary Turn on the power. Open the printer as if you are going to change a cartridge and then unplug the power.
Removing the rear cover. Looking from the rear, remove the T20 Torx screw on the left. This will allow you to remove the LIU (Line Interface Unit) cover and unplug the LIU. There are two push latches underneath that release the rear panel. It will hinge upward.
Cables Removing the rear panel will reveal some cables connected to the scanner. Disconnect them.
Removing the Scanner Tilt the scanner upward as if you are going to access the cartridges. You will see two large springs. Remove them. The front of the scanner pivots on two large hinges. Pry them apart with a slot style screwdriver. They will resist but will release and allow the scanner to rotate upwards. Rotate the scanner approximately 90 degrees and it will lift off of it's rear hinges. Use caution as you remove it in case you do not have all of the cables previously mentioned disconnected.
Removing the rest of the case There is a flat piece held on by four T10 Torx screws and two side covers that will hinge outward when two T10 Torx screws on each one are removed. When the side covers hinge outward they can be removed.
Removing the Service Station 1. Unplug the connector from the carriage drive motor. 2. Unplug the connector from the main electronics board. 3. Viewed from the front, remove the red screw from right side of the service station. 4. Remove the screw in the vertical frame to the right of the carriage drive motor. 5. Remove the screw in the vertical frame to the left of the belt tensioner. 6. Looking from the top, remove the two screws going through the carriage rod. 7. The vertical frame will now hinge up and come free of mechanism. 8 Looking from the front, there is a large latch on the right side of the service station. The wiring obscures it. Using a slot style screwdriver, release the latch and the service station will rotate CCW and lift out. Unplug the motor connector to free the service station from the mechanism.
Cleaning the Service Station. 1. Remove the service station motor by removing one screw. 2. Scrape as much congealed ink as possible from the service station. 3. Immerse the service station in hot water to dissolve the remaining ink. This will take a while but after a few rinsings nearly all of the ink will be removed.

Dear Bert, These instructions are absolutely great but I'm having a little difficulty taking apart the printer. It would really help if you could include a diagram lising all the parts of the printer. I figured out where the Line Interface Unit was located but when it got down to removing the service station and steps 1 through 8 I am totally lost. What do the initials CCW stand for?
If your still keeping up with fixyourprinter.com maybe, you can help me out. I would really appreciate it.
Thanks so much.

CCW means counter clockwise, i.e. rotate to the left.
I have a 30 page HP disassembly procedure for the Deskjet 900 series. The print mechanism is extactly the same as the Officejet G85. The document size is 5MB and in PDF format. You'll need Adobe (Acrobat) Reader to view it.
Click on my name on this post to email me asking for the document. Make sure you give me your correct return email request. (I've responded several times to incorrect addresses.)

Thanks for responding to my email. This printer is laying on my garage counter spread out all over the place. With your help and a whole lot of praying I'm hoping I can continue to take it apart and put things back where they belong. And just maybe it will work after all our hard work.
I'm am requesting your 30 page HP disassembly procedure for the Deskjet 900 series.
Thanks for being there for me.

I cannot send you the disassembly procedure unless you email me first. Click on the crossed tools to the right of my name. Make absolutely sure that your return email address is correct and not expired. Tell me exactly what you want.

Didn't you see Bert's comprehensive instructions above? I'll save you the trouble of scrolling all the way up there.

Hello, Does anyone have a part number for a COMPLETE service station assembly for a G85? The closest number I was able to find is C6426-40085, but that is just the spittoon base. I want an assembly I can just swap in, then clean the old one at a later time. Thanks,Mark

My girlfriend and I fix Officejet G85s as a hobby. We use HP 900 series Deskjets as parts donors, as well as the occasional G85 which is beyond help. Consequently, I have accumulated a few complete spittoon assemblies which I swap out whenever I service a G85 just like you are planning to do. It makes no sense to have to wait for spittoon parts to dry before putting a G85 back together!
Please contact me at doctuh at yahoo dot com if you are interested.
