Figure 7: Do not touch the electrical contacts
Gather the following cleaning materials:
Several clean, lint-free cloths or papers. Coffee filters and glass-cleaning cloths work well.
Distilled or bottled water. Do not use tap water, because it can contain contaminants that can damage the printhead.
Lightly dampen a clean, lint-free cloth.
Use the damp cloth to wipe the electrical contacts from the bottom to the top. Do not go past the edge between the electrical contacts and the ink nozzles. Repeat this motion until no ink remains on the electrical contacts.

Use a fresh, lightly dampened, lint-free cloth to wipe any accumulated ink and debris from the edge between the ink nozzles and the electrical contacts.

Have done all that but it is the area under the parking area at the right side of the machine that I want access to by removing the hinged lid and cover.
The area under there has a lot of sludge etc and I wish to clean it out
Thanks in advance
Disassembling the printer is relatively simple, and involving only one screw being removed and some cables being unplugged.
To begin removing the printer's hood, open the printer's mouth by simply pulling down on it; there are 2 mouth pieces that need to be pulled down.
Adjust the flap covering the scanner upward. When you are finished, the printer should appear as shown.
Remove the flap for the scanner. The flap is attached by a clip that can be dislodged by pulling lightly away from the printer.
Locate the three screws on top of the printer.
Remove the three screws from the top of the printer with a T-9 screwdriver as shown.
The screws are located in the far-left, far-right, and near-right corners of the printer, with respect to viewing from the front.
To access and remove the final screw attaching the hood of the printer, the face for the power button needs to first be removed as follows:
Reach into the mouth of the printer and press on the small clip behind the power button. This will enable the face of the power button to be removed.
A picture of the power button removed is provided to show the location of the clip that needs to be pressed.
After pressing the clip, pull out the face of the power button: right side to left side.
Remove the exposed screw that was covered by the power button face.
This screw is placed awkwardly. We found holding a T9 bit in a pair of needle nose pliers gave us enough leverage to remove it.
Do not try and torque the screw from an angle. This will ruin the screw's head, and make it even more difficult to remove the screw. Only remove it as already described.
This step is easier with two people. Carefully have one person lift the hood of the printer 2-3 inches above where it was resting.
The second person will now remove the ribbon cables and wires attaching the motherboard (the only green PCB board) to the hood by gently pulling upward on them.
When all three cables are removed, lift the hood away from the printer and set it aside.
After being separated from the printer, the hood is ready to be disassembled.
Remove the only screw on the printer hood's underside, as shown. Use a T-9 screwdriver.
You don't show the same model printer that I have.
I have HP model B210a Product No CN216B
There does not appear to be any drop down tongue
My touch screen is in the centre part of the scanner lid
Can you tell me how it comes off.
I shall try again in the morning as I am on UK time
Did not get your upload
So I still have not been able to get side cover off. I am reluctant to use force as plastic lugs are notorious for breaking.
Have been able to clean out a substantial amount og coagulated ink but access to more would be useful
