Canon Pixma printers are all-in-one printer/scanner/fax and copiers that can be used in home or at your office. Some Pixmas offer high speed printing at a pace of 7.5 pages per minute. The flatbed design makes scanning pictures or text documents as easy as placing the item on the platen and pressing the start button. While they are reliable and easy to you use and maintain, should you need to disassemble one you can do that at home as well.
Contact Canon to see if there is any warranty left on the product before you start to take it apart. Once the printer has been opened up by anyone other than an authorized service technician any warranty will become void.
