SOURCE: N5DS - How do i use it?

1. If you don't already have a micro sd card or reader, then get one.
2. Go to homepage of N5DS ( set language to english on site, go to download, and then download update v 1.19 kernel(English) to desktop.
3. If you don't have winrar to extract rar files go get the english version at and install it.
4. Extract the kernel for n5ds by right clicking it and click extract. Extract it to the desktop. open the folder until you see the folder with a bunch of files like .dat moonshell and stuff. then connect your micro sd reader to your computer and then put it in micro sd card. Once your computer installs it drag all those files into the micro sd card. Then when you turn it on it should work. What games were you talking about? like nintendogs and stuff? those are commercial roms and I cannot provide ayou a link to. Or was it homebrew games?

Your best bet for finding such information is on - it's an owner/enthusiast site that has a ton of technical know-how that is specific to the Civic. They have tech sections with step-by-step, photo-referenced procedures for a lot of work and I would not be surprised if they have information such as this. Also, pick up a Hayne's manual for your car (around $20 at a parts store) - their information is good and they have a lot of photos, plus all the torque specs you'll need. Just be sure to follow the instructions to the letter, especially when it comes to torquing down the cylinder head bolts - there's a specific pattern that you must follow.

It's definitely not a job for the faint of heart, but it can be done. You'll need a decent tool set (Sears has mechanic sets for around $100-150 that are more than enough, although you may find you need a specific specialty tool here or there that won't be included). You'll need a torque wrench as well - I got mine at Advance Auto Parts for $44 and it goes to 150 ft-lbs (more than enough for any bolt I've come across on a car). You also may find that a pair of steel ramps, to get the car's front end off the ground, are worth the $25 or so - it can save your back by bringing the engine up to you.

Remember though that when you remove the head, you have to remove the timing belt as well, and anytime you take a timing belt off, I'd highly recommend putting on a new belt and timing tensioner. If it's been awhile since the timing belt has been changed, or if you're approaching a 90k mile interval (90, 180, 270k, etc) you're due anyhow, so you should put in a new water pump, thermostat, and accessory belt(s) as well. There is a reason that the shops charge a lot - it's a lot of work, and if you are proactive with preventative maintenance (like doing the timing belt at the same time), it can cost even more.

It sound like you've installed an application which promises to 'speed up your PC' some something of the like.

I would suggest purchasing Antivirus, or Antimalware software as soon as possible.

If you would rather not purchase this software, there are free alternatives available but they tend not to be as effective.

ESET Nod32 Antivirus

AVG Free Antivirus

After installing either of these, they should pick up your problem and fix it for you.

Printer head error

Try updating, or reloading, the printers firmware using the "Fargo Workbench application. it can be found (along with the firmware file) in the "Downloads and Drivers" section, in the Support tab on

Print head errors come in a few ways. Some common issues i see are:

"Print head voltage error"
1. The wire harness, from head to pcb, is loose or damaged.
2. Print head is Damaged and needs replacement. Usually you will see dull lines going straight across your final prints, consistently.

"Head life error"
This error is primarily a mechanical failure. the belts that drive the head life motor have worn, and need replacement.

Mitsubishi p93 thermal printer streeking

Thermal heads show faults in two ways.
if a single line through print and you can see some colour in the print is is dust on head. Clean with isoprop alcohol and a lint free swab.

if it is a white line with no colour then its most prob a thiristor blown on the head, the white line will soon expand as other thiristors next the the faild one will soon also fail. A head replacement would be required. Is the head set at the correct voltage, replacement heads come with a test sheet and a value to adjust the head voltage too.

Risograph lines

lines could be caused by a bad mirror or scanner led light. or the thermal head that draws on your master. try to open your scanner table and make a master while it is open. check the lights if they are all complete. then check the mirror if there are chip offs on its mirror coating. if the led light and mirrors are in pristine condition then check the thermal head. try to clean it with a dump cotton cloth.. let it dry for a few minutes then try to make a master again.. hope to be of help.

White stripes on copies

Looks like some dots of the thermal head are defective. So the master at these dots cannot be punched.

I have a thin white line down one side of the print. i have cleaned each rolling feeder and also the thermal head. but still the white line is there.

I have noticed this with many printers, and usually the problem is the Drum Unit. Once the drum has become worn out, you will start to see lines through your documents. However this generally dont happen to the drums unless the machine has had alot of use.
I hope this helps you,

Thermal Paste


From the word itself it is a thermal paste that can hold the CPU and iot helps out to prevent the heat coming from the processor, when the cpu fan operate/spin it also that helps that processor to cool down.

You may try a toothpaste as a substitute for it you will need a "white base toothpaste" just put only a small amount into it.

Let me know for any clarification

Prints have a thin white line across all the images printed. Everything else works and prints are ok outside of the thin white line running horizontal across the 5x7 prints.

  • Thermal head — generates heat; prints on paper
  • Platen — a rubber roller that feeds paper
  • Spring — applies pressure to the thermal head, causing it to contact the thermo-sensitive paper
  • Controller boards — for controlling the mechanism
I think that you may need to replace your thermal head, A line means there is a place that the head can not head or it cannot recieve data

lol.. there's no thermal head on a
Ok..Print a big black square and run the machine maybe 300 prints until it starts pushing ink through, set the machine on darkest setting.. The ink in the screens is just old and sticky.. If you go through a case of paper (5000 sheets) and it still isn't getting better then take off the master and use some varsol and a lint free cloth (LINT FREE!) to dab and clean the whole screen to loosen up the clogged ink.. If that's not working then you really have to take the screen off and clean it first with varsol,, then some soap and water.. You have to be really clean about this because lint or any thing will cause white dots on your print. (hey this happened to me) If you've cleaned it really well you should take a clean scraper and prime the screen area with some fresh ink.. this is messy.. but it will get you going for good..

If you have a solid white line running the entire length of the card (think landscape style) you probably have a bad print head. I always tell people if you could place a ruler along the line and it is perfectly straight along the ruler, then that is a classic example of a bad print head. Check the MFG warranty for replacement or purchase.
