That is waste ink inside and all inkjet printers have it. You are probably using refills. They leak quite alot. If you can get at it or get the covers off easily, just use water and paper towels. Make sure you wear rubber gloves. It is a messy job.

How do oil get on the out side of the spark plugs?

I am assuming this is when the spark plugs are still in place and the oil isn't from a spill when someone has missed the hole filling the oil.
If it is a leak the most obvious place the oil is leaking from will be the rocker cover gasket. Make sure you clean the plug and it's mounting hole before removing it to reduce any oil getting into the cylinder.
Take a good look at the top of the engine, there is a bolt on, full length cover right on top of the engine. A lot of engines have the oil filler cap mounted into it. There should a be a seal between this and the top of the cylinder head.
Changing this gasket is fairly easy and won't affect anything important like mechanical timing. If you can, clean the engine as best you can with a degreaser as this will help hunt the leak if it isn't the gasket.
*Note* When you remove the old gasket make sure both the surfaces that squeeze together are completely clean before refitting the new one. Also make sure the gasket is lined up correctly to avoid leaks. A TINY amount of gasket sealant can be used to hold the gasket in place when fitting the cover.
The cover bolts are NOT in too tight. You should wind them until you hit resistance then turn it a small amount more, Then Stop.

How do I drain the oil out of my 2002 beetle

Pull oil dipstick. Remove the drain plug from the oil pan. Once that is empty replace plug. Then remove oil filter. Replace filter by filling new one half full with oil and smearing clean oil around the rubber seal on the filter. Reinstall and fill with engine with appropriate amount of oil. Confirm oil level on dipstick. Start engine and monitor oil pre and check for leaks. Recycle used oil and dispose of filter properly.

Ink is leaking out of ink tanks and filling up maintenance cartridge. Had a extra print head (used) and it did the same thing

1- Remove ALL the ink cartridges from the printer

2- Check that there is no residual tape on the cartridges.

3- Then clean the contacts on the cartridges as well as inside the printer itself

NOTE: Clean the contacts with a small amount of warm water on a cotton swab until no ink comes off on the swab.

4- If any of the other cartridges are low, empty, leaking or bulging, replace them with genuine and original ones.

5- Then turn off the machine and unplug it for 60 seconds

6- Insert the cartridges and check to see if the issue persists

Lost operating and maintenance instructions. Need to know how much oil to put into the self lubricating chain reservoir and where it feeds the chain to make sure there isn't a blockage anywhere.

You are free to charge to the top if you think right to use a chainsaw. It is essential that the oil is clean. If you accidentally charge too much (full hopper) it is good the rest of oil put back in the oil bottle or to extend on the chain. It is important that it is not oil-free and should be cleaned around the chain for good lubrication.

Oil pressure on my audi a4 is low after been service what will cause this

First check the Dip Stick and see where your oil levels are, if its low, then add more Oil as mechanic may not have replaced the correct amount after service. second, if you can reach your Oil filter in the engine just give it a tighten with your hand as it should only be hand tight. and thirdly look for any signs of an oil leak, either Oil spill inside the engine or under the car. Generally Oil levels should be full after any car service. Good Luck.

Leak from the ice maker

I would first try to determine if the tray is level. There are usually screws that allow some side to side adjustment.

If the tray itself is actually leaking, you probably will have to replace the icemaker unit.
