This tutorial describes how to make a cd tray for little or no money. It is pictured below. Or you could buy one on ebay for about $20.
The initial idea was found on StevesForums. Most of the credit is theirs. The reason I have this tutorial is to give what I have learned in a straight-forward how-to. The original StevesForums post is now 77+ pages, so weeding through it to find what works and what doesn't work could possibly take 4-5 years... or more.
Although all of my testing is done on my Canon Pixma IP5000 this tutorial applies to several Canon printers with CD/DVD printing abilities. Where applicable I will tell you where the models differ.
What you'll need:
A Canon Pixma Printer that has the ability to print on disks. You can tell because there is a fold down plate on the front of the printer (image 0B).
A flat head screw driver
About 5 minutes of time (10 minutes if you read all my dumb comments).
Step 1: Enable the Printer- Remove the cover.
The steps involved are as follows:
1. Removing the front flate covering the CD-tray opening (pictured).
2. Set the printer's BIOS to non-US (next step).
