With regards to the uneven spot, the ink supply is a little bit lacking, try to increase the ink density, ot there might be some dried inks in the nozzle of the ink distributor inside the drum unit, open the drum and clean the holes of the bar inside the drum. another one is, your impression roller might have deformities, another is your metal screen is punctured and the last the screen might be clogged.

SOURCE: after the riso makes a master it cuts off the top of when printed

Is this machine interfaced with the computer? if it is.. then it's nothing to do with the machine... Either it's the machine settings.. So you have selected letter size on the machine and ledger on the computer.. Something like this. The machine is probably fine..

Riso's are famous for this, i will scrub the rubber timing roll with rubber rejuvenator and clean the steel roll with alcohol.

the riso paper feed clutches are weak compared to what they were in the GR series you may have to replace the clutch.

How to adjust the feed dog tension on Singer CG550? It isn't strong enough to hold the fabric in place - stitches are uneven. My old Kenmore had an adjustable button on top above moving needle pole.

you are referring to the walking foot tension
ask a sewing machine repair shop how to adjust it
could be a lock washer held in place by a set screw where you loosen off the screw and push it closer against the spring and re tension the screw

Washing machine spins uneven

if it is a front loading machine, the drum is held in place by a bunch of mini shock absorbers. If one of them is bad or broken it will spin unevenly. There are usually 8 shocks, 4 on the bottom (2 in front, 2 in back) and 4 on the top. The bottom can be inspected by taking the bottom face plate off (usually held on with clips) the top by taking the top of the machine off (usually held on with screws in the back of the machine).

My dishwasher does not clean all of the equipment within, i have noticed that the top and bottom water rotary spray arms do not spin when machine is on.

Check that the arm outlet jets at the trailing end of the arms are not blocked with food particles and other solid matter. This often happens and the arm is unable to turn because the water jet that is supposed to drive the arm does not have the force to rotate it.

Rough, uneven Cotton Load spin cycle

Make sure the washer sits level on the floor and that the machine can't be rocked around due to uneven foot adjustment. The feet usually have rubber cups that cover the metal bottoms--one of the cups may be damaged or missing entirely. Hope this helps!

After washing my machine smells like stagnant water


First check to make sure that the machine is draining properly and that the pump filter is clear of any debris.

If the machine is a frontloader a common place for mold to build up is the rubber seal around the door. Clean this out as well as you can with ordinary kitchen cleaner then place a heaped cup of baking soda directly into the drum and run an empty hot/boil wash on a full cycle.

Baking soda has a cleaning and neutralising effect and will help remove any build up of mold or gunge within the machine. You may need to run two of these washes before you see a solid result.

Thereafter I recommend you run a monthly 'maintenance wash' with the baking soda to prevent the problem arising again.

Hope this helps. Thanks for using FixYa.

I'm getting lines across all copies I insert via the feed

Yep. remove and clean that small strip of glass on the left side of the machine. open the feeder, there are 2 phillips screws, that glass either has somthing on the top or bottom surface.
It makes it easire to clean when you remove it and place it on a white sheet of paper, that way even if it is a really small spot you can see it easier.
The lamp does not move when you use the doc feeder and a small spot on that glass will make line across the entire page.

Indesit 1600 WE165 washing machine - filling with water after wash

Doesn't sound like a filter problem to be honest. If the water that's coming in is clean, you're probably looking at a leaky inlet valve. With the machine unplugged from the mains, remove the top, then look for the valves (which are the items that the inlet hoses screw into). One at a time, remove the rubber hoses that connect them to the various bits of the insides of the machine to identify which valve is leaking. New valves are available quite cheaply on the net, and are easy to install. If the machine is filling up with dirty water, it's probably being siphoned back in from the drain. The drain hose mustn't be a tight fit in the standpipe it hooks into and mustn't poke in too far. Also, the standpipe needs to be reasonably tall. Have a look at page 7 of - it's a manual for a different model, but the drainage requirements will be the same. A.
