How to make your printer run cheaply


This hint is not strictly Macintosh, but it’s so good I have to write it up. Did you know you can get what they call a Continuous inking system (CIS) for most big name inkjet printers? It continually feeds the ink into the printer so you don’t have to change the cartridges! You can see the big containers of ink in the photo above – they sit next to the printer.

Here is a picture of the inkjet cartridges which replace the old inkjet cartridges. These new ones have little tubes running from the ink tans into them to deliver the ink.

I purchased mine from RIHAC in Melbourne, Australia. They have a good unit, with good instructions as well as good phone support, the sell the CIS system for about $150 and it comes with I think it was 100ml of ink per color. Installing the CIS system is about the same complexity as changing a pushbike tyre, or sewing a button on a shirt. If you can follow instructions, you should be able to install it OK. Mine’s been going about 2 years now with no problems at all.

How to imod a 4th Gen iPod photo


I talked about the audio quality of the various iPods, and mentioned a mod for 4th and 5th Generation iPods that gives them excellent audio quality rivalling that of a $1500 CD player. Well, here is how to do the mod on a 4th gen color iPod photo – Apple model number A1099.
The 4th Gen iPods have a Wolfson WM8975 audio chip in them.
The pinout is something like this (this is a pinout of the WM8971).
ROUT1 and LOUT1 go to the headphone connector, via some capacitors etc, while ROUT2 and LOUT2 go to the dock connector (line out). There are resistors, capacitors and inductors of low quality on the signal path, but the Wolfson IC itself is a top of the range audio chip. The mod involves running a wire directly from LOUT2 and ROUT2, via some Black Gate capacitors, to the headphone jack, which will now become a high quality  line out. You could run it out the dock connector instead but I decided to go out the headphone jack – it loooked easier!
You’ll need a 4th gen ipod photo and a pair of Black Gate NX Hi-Q 6.3V 22uF or 47uF capacitors – they are rare and expensive. You can find them occasionally on ebay. They are no longer made but suppliers sell them off in pairs from time to time. My pair of 47uF caps cost me $16 pounds and I had to import them from the UK! Here’s a list of alternative capsyou could try.
This is the ipod photo 4th Gen, it’s the color version of the 4th Gen ipod. :
Here’s my ipod open and Black Gates ready to go…
Step 1. Solder and heat shrink some small leads onto the black gate capacitors…
Step 1. Solder leads onto the black gate capacitors. I used wire wrap wire - strong but thin.
These are the resistors we will remove - they are tiny - about 1/4 the size of a grain of sugar. (This picture is magnified)


Step 2. Remove the output resistors from the wolfson DAC
Step 3 - Solder one wire from each capacitor to the output of the DAC chip. (Click on image to enlarge)
Step 4. The other wire from the capacitor needs to be soldered to the headphone jack. The inductors closest to the headphone jack are removed.
Step 5 - shove it all back in and try not to break the wires! I had to remove the plastic sleeve around the dock connector to fit the capacitors in. The capacitors sit each side of the dock connector (bottom left).
Some tips:
I used a headphone lead to hold the socket while I soldered.
I used a 500W floodlight to help me see - the soldering is fine.
Actual size of resistors! I wouldn't attempt this mod unless you have had Surface Mount experience before...

How to speed up your mac with a Solid State SSD Drive


I just upgraded  the boot drive on my Mac Mini to an SSD drive and it’s by far the biggest speed enhancement I’ve experienced on any computer! The speed increase is incredible – almost hard to believe – boot time went from 60 seconds to under 30 seconds, and applications launch instantly – no bouncing dock icon.
This is not for the beginner, it’s quite technical, but here’s how to do it.
Now you could upgrade your entire hard drive but with a 480G SSD drive costing $1579.99, it’s not a cheap option!  But you can upgrade just to a smaller boot drive (a 64G drive costs $119) to run OSX and your applications. This means your system files and applications are on the new SSD drive, but your user data (iphoto, itunes etc) stay on your old Hard Disk.
SSD Boot Drive using a different drive for my user folder - less than half the 64G SSD is used!
An SDD drive looks the same shape as a traditional drive, making it easier to install, but it uses memory instead of a hard disk so it is much, much faster. If your computer is a bit old and slow this may be a better solution than upgrading your whole computer because often it’s not the processor speed that slows things down but the hard drive.
Here’s how to set up an SSD drive to run your OSX and applications off, and keep using your existing hard drive for your user files.
1. Work out how big a boot drive you need.
Everything except your user data will go on the boot drive. To work out how much space you need, do this:
(a) Find your total disk usage. Click on your hard drive and press Apple-I, check how much space is used. For me it’s 587 Gig:
(b) Find your user folder usage. Select your user folder (the onew with a house as an icon – this is where all your documents, music, movies, photos etc are stores) and press Apple-I, it may take a while to calculate it.) If you have more than one user, you’ll need to do it for each folder and add them up. I only have one user and for me it was 550GB:
Subtract (b) from (a) to give you the amount needed for your boot drive.
587GB – 550GB = 37GB.  I need 37GB for all my apps and system software. A 40GB drive would just to it, so I went for a 64GB drive.  I ordered a 64GB M4 SSD from Crucial in the USA  for US$119.
2. Connect the Hard Drive to your mac.
For a mac pro it simply connects into the spare optical bay slot – no adapters needed, a 30 second operation.
Difficulty: easy – 30 seconds.
For a new aluminium mac mini it can replace one of the internal drives.
Difficulty: moderate – 1/2 hr.
When I replaced the internal SSD drive in my mac mini I needed to pull out the fan and motherboard to get the new SSD drive in! You can get the old hard disk out without pulling out the motherboard but the SSD drives are actually ever so slightly thicker and more uniform in shape so the motherboard needs to come out to manoeuvre the SSD drive in place.
For a macbook or macbook pro you’ll need replace the internal optical drive with your old Hard Drive (OWC who also sell SSD drives provide a kit to do this here) then to put the SSD drive where your old Hard Drive was. The other more expensive option is to order a large SSD drive and replace your old hard drive with it.
Difficulty: hard – 1-2 hours.
iMac: Forget it! Your simplest option is to put the SDD drive in an enclosure and leave it plugged in all the time.
3. Format the SSD Drive using disk utility.
After your SDD drive is plugged in you’ll need to power on your computer and use Disk Utility to format it – Mac OS Extended (Journaled):
4. Copy everything except your user directory onto the new boot drive.
Now you need to copy your system folder and applications onto your SSD drive. You can’t do this by hand – there are hidden files that need to be copied, so use Carbon Copy Cloner. Using Carbon Copy Cloner, select your boot drive as the target Disk and then select Incremental backup:
Now select your main hard drive as the source disk, but then deselect your main user directory so that you don’t copy across all your user data (it won’t fit!)
Click Clone and your boot disk will be created on the SSD disk.
5. Reboot from the new SSD boot drive.
Under System Preferences click Startup Drive select the SSD Drive, then restart! (wow – notice how fast it is!)
Since it is now looking for your user data on the new drive, it won’t find anything and so your desktop and dock will be the default ones and all your files will be missing. Don’t panic – in the next step we will get your old files back.
6. Select your old User folder.
Go to System Preferences, then Accounts, (in Lion this is now called ‘Users and Groups’) then ‘Click the lock to make changes’ and control-click the main user account and click Advanced Options.
In the advanced options tab choose your old user directory, which is back on your original hard drive.
Your computer will tell you that you need to restart, and when you restart you will be running off your new boot drive,with your user directory on your old hard disk.
So how fast is it? Here’s a demo of how quickly applications launch from my new SSD drive…

What to do about “The optical photoconductor needs to be replaced” printer error


There appears to be a compatibility issue with Mac OSX lion and lots of printers.   (Talked about here on the apple support pages)  The printer may or may not work properly, but you will get an error that says “The optical photoconductor needs to be replaced.”
When I try to print on my new Fuji Xerox document C4350 last week I got an error saying “The optical photoconductor needs to be replaced.” and the printer would not even print.  If you play around with a different print setting (e.g. USB, Jetdirect, LPD, IPP) you may be able to get the printer working (still with the error!) till Apple repairs the problem. Here’s how I got my Xerox printer working.
How to get a Fuji Xerox Printer working with OSX Lion
I just purchased a Fuji Xerox Docuprint C4350, and there have been a couple of issues getting it running.
1. Installing the Drivers
The 1st issue is that the Fuji Xerox drivers from the website do not run under Lion, they are PPC code which means you need to have a PowerPC computer or Rosetta to run the installer. The actual PPD files are fine however, so the workaround is to install the drivers onto an older computer (I used my old G4 Powerbook) and then copy them via thumb drive or e-mail onto your new computer.
In my case the file was called “FX DocuPrint C4350 PS.”  The Installer puts it into the Library/Printers folder and you need to move it anywhere on your Lion machine then when you are selecting the driver  choose ‘Other’ and find the file.
2. “The optical photoconductor needs to be replaced.” ERROR
After setting up the IP address on the printer and then selecting the computer to print using IPP printing, whenever I tried to print I would get the error “The optical photoconductor needs to be replaced.” Not only this –  it would pause the printer queue and not print the page! A little Google search shows that this is a common error under Lion.
In my case I found 2 other ways to get the printer working.
The 1st was simply to plug it in by USB instead of Ethernet printing. This gave me no errors at all and the printing works fine, it’s just a bit slower.
The 2nd way was to still use IP printing but select HP Jetdirect – Socket instead of IPP printing. Xerox calls it port 9100 instead of JetDirect so make sure on your Xerox printer you enable port 9100. This still gives the error, but the printer at least prints the page normally.

How to match the colours on your monitor to your printer.


If you have ever designed a colour document on your computer and then printed it out on your inkjet or laser printer you may have noticed that the colours come out slightly different.  This is partly to do with the fact that  printing with ink on a piece of paper is a different process to creating colour on a computer monitor,  but it is possible to calibrate your monitor so that the colours match up as closely as they can.  This article gives you some tips on basic monitor colour calibration.
The colour on your Printer
Every printer uses slightly different inks and so the same ink combinations print out slightly different hues  on different printers.  Built into every Apple Computer is a technology called ColorSync which tries to address this problem.  ColorSync tries to match the colour on the screen with the colour that is printed on your printer so that if you choose a particular shade of green on your computer monitor, that same shade of green will be printed on the printer. It’s not failsafe, but it helps.
Apple computers come loaded with printer drivers for most printers, and these printer drivers contain the information that the computer needs to know how the printer will print certain colours.   Most printers will have a different colour profile for each type of paper you are printing on, so as long as you select the right type of paper (e.g. Gloss Photo, plain etc)  your Macintosh will know the colour that is being printed by the printer, and will try to match it to the screen.
The colour on your Monitor.
Different monitors display the same colours slightly differently. In most cases your OS X computer  will automatically detect the monitor  that is connected to it and use the correct colour profile for that monitor to try to match what you see to the colour that will print.  You can adjust the profile of monitor yourself and this article explains how.  What you see on your monitor is affected by your contrast and brightness settings, the age of your screen, the light in the room you’re working in, so it’s worth calibrating your monitor manually anyway.
Here’s  how to calibrate  your monitor using the built-in Apple calibration tool.
1.  Go to the Apple menu and open the System Preferences,  and click on “Displays”
2. Click on the ‘Color’  tab  and you will see a list of ‘profiles’  with one of them highlighted in grey. In my case ‘Cinema Display’ is  highlighted because I have an Apple Cinema Display.
Click on the color tab of the displays preference pane.

3. To manually calibrate your monitor, select ‘Calibrate’.  Don’t worry about losing your existing settings because at the end of the process you will be asked for a new name to save the new settings under. A calibration assistant will appear, choose ‘Expert Mode’ and then Continue.

There are 5 or 6 steps to the process, it will take you through them one by one, asking you to compare colours and move sliders. Sometimes it can help to squint.
Step 4 in the setup is called “Target Gamma”. Just go with the recommended 2.2.
Step 5 is Select Target White point. You will notice it dramatically changes what you see on the screen! It is trying to emulate the difference between looking at  a piece of paper under different lighting conditions. A piece of ‘white’ paper will be yellow or blue depending on the surrounding light conditions. White Point is setting the colour of your ‘white’. I suggest holding a white piece of paper up next to your monitor and matching the monitor white point to that. This way your monitor white point will be the natural whit point of your room. It may be that your room has an un-natural blue light and you’d prefer a more natural white point, it’s personal preference, but it will change the way you perceive colours on your monitor. I like to make a few different profiles with different white points and then I can easily switch between them. The standard white-point setting is 6500.
Step 7 is give it a name and then you are set.
I have my general monitor calibration setting. It’s set up for mainly internet work.
I also have one I use for professional printing jobs that I’ve tried to match to the printer I use.
Sending something off to get printed.
There are some colours that you can create on a monitor  that are impossible to print on a normal inkjet printer! For example certain oranges, fluorescent colours etc. The way the get these printed, for example on a logo, is that you specify the colour you want from a sample sheet of colours the printer gives to you. The printer then uses that coloured ink, rather than the normal CYMK ink. This is called spot colour. If you are doing a one colour logo or a T-Shirt you may want to choose a spot colour.
If you want to be certain of a particular CYMK colour you are printing you can get a pantone colour sheet from your printing company, it looks something like this:

Each colour entry tells you the CYMK values for that colour.
For example, here’s a sample orange colour from the printing company.
This means that if on your macintosh computer, you go to the colour picker in any program, and choose the CYMK sliders, you can set C to 0, M to 68, Y to 100 and K (black) to 0, and choose this exact colour.
Now that you have put in the exact colour by numbers, it doesn’t matter what it looks like on your screen or home inkjet printer. When you send it away and it gets printer by the printing company that sent you the chart, it will be EXACTLY that colour that you saw in their sample chart.
If you have a pantone colour chart from a printer (they are free -you just need to ask for one) you can put some of the colours into a color-filled box in a program like Pages and see how close your monitor (or home printer) is to the actual printed colours. This will give you an idea as to how well your monitor (or printer) is calibrated.
In the end, when doing Desktop Publishing, the main thing to remember is never trust your monitor, especially when choosing colours or editing photos, always check the colour of the printed out version.
